Young PIs in action: an interview with Dr Kyle Lauersen

On our latest “Young PIs” interview series, I had the pleasure the interview Kyle Lauersen who recently got appointed as an Assistant Professor. Even though we have many common connections (and we have published a paper together), we never had the chance to discuss, so I listened to his answers on my questions with great interest. I hope you enjoy the post as much as I did!

Kostas Vavitsas: Where did you start your research and how did you land your current position?

Kyle J. Lauersen: I moved to Saudi Arabia a about a month ago. I left Germany a few days before that to spend some time with my family and friends in Canada before making the exciting transition to KAUST.

I did my undergraduate, teaching degree and Master’s at Queen’s University in Kingston, Canada. I then moved to Germany to do my doctorate at Bielefeld University, under the supervision of Prof. Dr. Olaf Kruse in the Center for Biotechnology (CeBiTec) facilitated by the CLIB Graduate Cluster scholarship program (part of Horizon 2020). By the end of my doctorate, I was able to demonstrate that a specific strategy of spreading an enhancing intron throughout codon optimized transgenes to minimize exon lengths and mimic native regulation machinery could mediate their reliable overexpression from the nuclear genome of the alga Chlamydomonas reinhardtii. This technology enabled us over the last 5 years to demonstrate numerous examples of heterologous gene overexpression and the first examples of concerted metabolic engineering with this eukaryotic algal host, work which was largely done during my Post-Doc time also at the CeBiTec with Prof. Dr. Kruse. See our patchoulol paper.

I was very fortunate that I was able to act in a sense as a junior group leader and had the good fortune of working with (now Drs.) Thomas Baier and Julian Wichmann in an intimate team dynamic with complementing skills and expertise. Together with several bachelors and masters students we could focus on algal biotechnology and produce some solid work over the last 5 years.

How did I get my position? I think I came at the right time as KAUST is expanding towards impact focussed and translational research, so our work using algae as green cell factories really tweaked local interest. I was invited to KAUST to give a presentation on collaborative work with Prof. Salim Al Babili and at the end of the talk several senior faculty members approached me to ask if I would be interested in coming to KAUST. At that point I was applying for other faculty positions, so I accepted an interview and was back within a short time to conduct an intense week-long interview. At the end, I was informed that the Division was interested in hiring me as a Faculty member and, after a very short amount of thinking about it, decided it would be an excellent place to grow an algal biotechnology hub.

Kostas: What are the particular challenges of working with photosynthetic microbes?

Kyle: I always wanted to work with photosynthetic organisms. My undergrad research background is in plant biotechnology, I was engineering trees during my undergrad with Prof. Sharon Regan at Queen’s and engineering grass and ice binding proteins with Prof. VIrginia Walker during my Master’s. Also, I am a green guy, I didn’t want to work, say, with animal models. Compared to these systems (or most heterotrophic microbes), algae are easy to handle, smell better, and illuminated cultivation spaces full of green things (or other colours) are generally nice to look at. 

I think we are reaching a point where we need to be resource efficient. We like eating, we like breathing, being mobile, wearing clothes… all theses things are powered, at their origin, by photosynthesis, which makes working with photosynthetic organisms an incredibly logical pursuit.

The biggest challenge of working with algae is the limited investment in research time compared to heterotrophs. So generally, although we build on our predecessors, we are often doing work which has long been figured out in other hosts. Algae research used to be a small part of bigger plant-oriented labs, and only recently we see more dedicated algae research groups.

Now some needed technology is emerging, mainly overcoming technical challenges of how to grow algae in industrial settings or overcome the space-time yield limitations of phototrophic cultivation. Reactor designs like the Subitec system and those coming from CellDeg with CO2 permeabilization membranes are generating truly impressive yields of biomass from CO2. Aggressive and systematic handling of phototrophic microbes is also improving our ability to engineer novel traits. We can get Chlamydomonas transformants in a very short time (4-5 days) and combined with the MoClo or our (pOptimized) modular vector systems, I think we’re at a golden age of possibilities for engineering improvements in these hosts. Also the amenability to microbial handling with robotic systems will improve our turnover rates, which is a great advantage.

Kostas: Sustainability as a common theme among the researchers we interview. Will it bear fruit?

Kyle: I’m very optimistic that what we’re doing will have a real impact in the future. Photosynthetic biotechnology is one part of the greater spectrum of sustainable technologies that are rapidly needed, advancing and coming to market. One good applied example of this is on-site carbon capture, algae can sequester CO2 in the same facility where it is emitted. And keep in mind that there is no faster way to produce photosynthetic biomass than by algae (in the right cultivation set-ups).

The sustainability argument is of course not limited to photosynthetic organisms. And any applications need to be combined with other technologies to become more efficient. What we’re doing will not ‘save the world’ on its own, but it is one incredibly important piece of the puzzle. So we need to boost translational research within the field and increase communication between stakeholders at all levels. This is something that we are seeing now in many EU consortia, like the Horizon 2020 project Photofuel (among many others), which I had the pleasure to take part in 

Kostas: How can we better do translational research with algae? 

Kyle: There was a lot of hype in the field through the last 20 years that has made investors more skeptical on the commercial value of algal applications. But this means that we need to make our argument stronger and provide real practical examples of where algal systems really shine. For example, Algenuity is working on interesting applications of reduced pigment content Chlorella, a great protein source. I think important goals now are to produce a lot more clean biomass of high quality, and demonstrate engineered algae in high-density cultivation concepts that compete with yeast or prokaryotic counterparts. And we need to engage more with material scientists, process designers, and chemists to tailor our lab-scale practices to be amenable to outdoor, or large scale cultivation.

Kostas: When is the right time to apply for a PI position?

Kyle: I don’t have any real wisdom to offer on the topic. I was lucky, I applied only to 10 other positions, which in itself was an emotional rollercoaster over the course of a year..

The process is a bit of a soul-searching exercise. I am Canadian, and I had obtained permanent residency in Germany, had culturally adapted, and had a very good working environment at the CeBiTec. Whenever I was applying to a position I had to imagine myself living there. And when you move to a new place it is a mental hurdle to readapt. Mobility for scientists is both a blessing and a curse: you get to travel but you have a nomadic lifestyle.

Coming back to the question, when to apply… it depends where you are and the support you have. In my case, although I had a great network around the world and Bielefeld was a fantastic incubator, I couldn’t materialize my connections into a permanent position as my network consisted largely of algae people and their institutes weren’t looking for more. What I should have likely done is go to more generalist conferences or meetings and advertise myself to a broader audience.

Kostas: When did you decide you wanted to become a PI? Have you contemplated other roles?

Kyle: I can tell you exactly when. It was during my research internship the summer before my fourth year BSc honours thesis. I walked into Sharon Regan’s lab, and I saw miniature poplar trees growing in sterile magenta boxes in MS agar medium. This was the first time I had seen anything like this and I was instantly hooked, I knew I wanted to stay in such an environment and become a PI. I tried some business and entrepreneurial projects, but academic research always pulled me back.

Kostas: What is the advice you would give to early career researchers in synthetic biology?

Kyle: You have to be self aware and surround yourself with people that can teach your things and work with you to a shared goal. In your younger years you should explore as many things as possible, later during your PhD you should focus, build a team around you and get alot of output.

Put your emotions aside and work really really hard, be consistent, get up everyday, go to work, and be very vocal. Communicate your expectations and work.

Keep networking. Career progression in science is to a large extent merit based, but it will only take you so far. For example, I don’t have any Science or Nature papers (yet?), but the team in Bielefeld and I have produced some pretty solid research. And don’t forget to develop your soft skills!

Young PIs in action: an interview with Julie Zedler

A few months ago, I was delighted to hear that my former colleague Julie Zedler secured a tenure-track position in Jena, Germany. I couldn’t miss the chance to interview her for our “Young PI” series; you can see the result of our chat below.

Kostas Vavitsas: The sustainability theme is pretty common among the fresh PIs we interview. Do you think synthetic biology research with photosynthetic organisms can really make a difference in the climate change front?

Julie Zedler: The answer is 100% yes – even though this will almost certainly take longer than we would like. Personally, I believe that photosynthetic organisms are an often neglected player in climate change discussions that we need to raise awareness for. I think the fact that there is a large number of young PIs working with sustainability in mind is very encouraging. However, in order to address big socioeconomic challenges like climate change, we need a critical mass of people and funding bodies to be onboard with the idea. Young scientists interested in making a difference is the first step to finding sustainable solutions but the support infrastructure also needs to be in place to maintain our forward momentum.

Kostas: What is the biggest advantage and the biggest disadvantage of working with photosynthetic microbes?

Julie: I would say the biggest disadvantage is at the same time one of the biggest opportunities: the field of photosynthetic microbes, especially when it comes to applications, is still very young. This makes it sometimes difficult to convince industrial partners and funding agencies to put their weight behind photosynthetic systems. At the same time, photosynthetic microbes have a huge, largely untapped potential. This is super exciting and probably also one of their biggest advantages. Another big advantage is that they are extremely visual and their benefits are intuitive – when talking to a non-scientific audience they almost speak for themselves.

Kostas: When is the right time to apply for a PI position?

Julie: I don’t believe that there is a “right time” to apply per se – often these things come down to the timing of available positions or funding application deadlines and you always need that little bit of luck (combined with hard work of course). I would recommend keeping your eyes out for funding calls and open positions and remember it is almost never too early to apply but it could easily be too late…

Kostas:  How do you feel about your new role? Where do you see yourself in the next few years?

Julie:I am very excited about my new role and I am very curious about what the future holds. Being a young PI, I find it quite important to be an appropriate role model for my students. I am currently building my group and kicking-off work on a number of ideas and research interests that I would not be able to cover on my own. I still do enjoy the occasional bench work though and I promised myself I would stay connected to the practical aspects of research for as long as possible. Looking forward, I think we need to make an increasing effort to communicate what synthetic biology is and how it can impact our everyday lives – it’s crucial to get the public to tag along with scientific progress and explain how and why we think this is the way forward.

Kostas: A comment on equity in science, do you think women have a longer or more challenging road to professorship?

Julie: Personally, as a female scientist, I have never felt disadvantaged. However, numbers speak for themselves and women are still clearly not equally represented (especially when we get to the PI stage), therefore, I am an active supporter of women in science. In all three countries I have worked in, UK, Denmark and Germany, there are efforts to ensure equal opportunities at universities. However, in this respect, Scandinavian countries might be a little bit ahead of the rest of Europe. Overall, I think the biggest problem, both for women and men, lies in the incompatibility between academic workloads and a healthy private life. We need more support and flexible, tailor-made solutions for individual career choices. I believe that nowadays equality challenges are largely of societal nature – when gender stereotypes are finally overcome this will also be reflected in the workplace.

Kostas:  What is the single most important piece of advice you would give to an Early Career Researcher in synthetic biology?

Julie: My students would probably say that I always tell them to do their controls – which I do say over and over again. Specifically concerning SynBio, I think we have to remember that this is a quite young, emerging field. There are high expectations but it is up to all of us to put the work in to make the field thrive. So grab your opportunities and make the most of them!

Young PIs in action: interview with Ciarán Kelly

In our next interview of our “Young PI” series, I had the pleasure to talk to Ciarán Kelly from Northumbria. As you will reed below, Ciarán gives a detailed account of his endeavor, and he is now ready to tackle sustainability issues with his research.

Kostas Vavitsas: Probably the most important question of the day: how do I pronounce your name?

Ciarán Kelly: It’s pronounced keer-awn, an Irish Gaelic name. It translates to little dark one, which I interpreted as meaning mischievous one, which I think kinda describes me.

Kostas: You just started your new position in Northumbria University. What is this position and how did you end up there?

Ciarán: Yes, it is at Northumbria University in Newcastle, UK, and I am a Vice-Chancellor’s Fellow. This is a three-year internally-funded university fellowship to start my own research group.

I am from Ireland, and I moved to the UK in 2002 to study genetics at the University of Glasgow. It was there that I was introduced to genetic circuits, while working on the circadian clockss of plants. At the same time, in 2007,Glasgow Uni participated in iGEM, and it was the first time I had heard the term synthetic biology. This really piqued my interest and I wanted to know more about this thing.

After finishing my honours degree and doing some travelling, I decided I wanted to do a PhD. I came back from sunny Australia to live in  Dundee, in the north east of Scotland, where I worked on putting synthetic biohydrogen-producing pathways into microorganisms. The enzymes that produce hydrogen, hydrogenases, are generally ruined by oxygen and require complicated metal cofactors, so there was a lot to try to get right! After a few years of work I managed to produce tiny amounts of hydrogen from my synthetic pathway, a common problem for many metabolic engineers! This made me want to get a better understanding of the field, and in particular an interest in synthetic biology tools.

I then moved to Oxford for a one-year postdoc, which was not meant to last for only a year…

Kostas: What happened?

Ciarán: Well, the PI had recently moved to Oxford from Imperial, and after 6 months he announced he was leaving to go to the US.

After the initial shock the situation worked well for me. I was able to start some independent projects, I negotiated a research budget with the department and started some really fruitful collaborations, including one with Prof. Antonis Papachristodoulou in Engineering Science

As I was living in London and commuting daily, at the end of this year I moved to London and the Centre for Synthetic Biology and Innovation at Imperial College. I joined the group of Dr. John Heap, a new PI who was interested in metabolic engineering of non-traditional microbes. He also wanted to focus on achieving high product yields. I worked on various projects in different organisms, including cyanobacteria (your organism of choice, right?). I dipped into the cyanobacterial world, and I found there was a lack of good tools. So I decided to work in that space and came up with a few useful tools to control gene expression in cyanobacteria, such as inducible promoters,  terminators etc.. 

At this stage, I was encouraged to start applying for independent funding. I didn’t have a “superstar” paper, but I’m starting to get some solid first-author publications out. I took a short-term contract in Oxford to finish up some experiments for a paper with the engineering group. This involved engineering small RNAs for use in synthetic negative feedback circuits and working closely with modellers, which was a fun experience. I think when I started my PhD I was initially sceptical on how “engineerable” biology could be, but now I’m now a full convert! I then applied for a LOT of fellowships, which although they were rejected, got good reviews, encouraging me to keep going.

And then eventually this opportunity came up and now here I am!

Kostas: There you are. What is the theme of your current research?

Ciarán: That’s a good question, I ask it to myself all the time. My interests are quite varied, but in general my interests are in metabolic engineering of complicated pathways for sustainable biomanufacturing. I am interested in optimising metabolic routes that are, say, 15 catalytic steps long. Producing and maintaining all of those enzymes at the right levels in a non-native host is a big challenge, and I want to use new and existing synthetic biology tools to make it reliable.

Kostas: When is the right time to apply for a PI position?

Ciarán: I can’t say that there is an answer that fits everyone. In my case, I was a bit slow initially in getting publications. So even though I felt ready intellectually and experience-wise some time ago, I had to be realistic and take into account that you need good papers and an interesting research story. So it’s a trade-off between getting those papers and spending a substantial amount of time on putting together a  strong application.

I learned a lot from applying for a postdoctoral fellowship. It makes you start to come up with a good proposal. We hear all the ways synthetic biology can and will change the world, but you need to think about what part you can play in this mission. The more proposals you write, the better they become, as you get feedback which you incorporate in later applications to tweak the ideas etc.

Kostas: But there are also differences between PI and fellowship applications, right?

Ciarán: There are similarities, but also notable differences. As PI positions usually have the title of lecturer, they give emphasis on teaching qualifications – something that some of us who have been in research-only roles tend to ignore. I would try to take up teaching duties whenever you can, for example, asking about doing some tutorials, lectures etc.

Kostas: Do you feel that your training as a PhD and postdoc prepare you adequately for independent positions?

Ciarán: I was very lucky with the mentors I had. They were great at sharing insights into how science is done and how a lab runs! I recommend to seek mentorship as much as possible. Your supervisor, other experienced postdocs, fellows and other friendly PIs.…scientists are never shy to give advice if you ask! Of course you will need to filter it and keep the bits that work for you. This will help get you there and prepare you for independence.

But there is another thing to keep in mind. I don’t expect to be suddenly transformed into the world’s best PI. And I think that’s okay! It’s just another stage in my career development, which will happen in any new role. I’m seeking feedback from  colleagues and listening, I’ll try out a few things, I’ll make mistakes, and hopefully along the way I’ll become a better PI.


Kostas: A comment on mobility? You moved to quite a lot of places.

Ciarán: Not as far as you!

Kostas: That’s true, but I’m asking you…

Ciarán: Lots of it was due to circumstances, but I was always looking for good opportunities to go to new places, and I have benefitted from that. I have seen a few different work cultures. That said, I’m happy that I could stay for three good solid years at Imperial and get some things done.

Sometimes you have to move, like to do a particular piece of work or collaborate with a certain group, or live with your partner! It’s common and easier to do early in your career, as at some point  you might want to set down some roots .

Kostas: Last question. How do you feel about your new role?

Ciarán: I’m really excited! I was offered this position in April and I feel great about it. Now it’s time to get some grants, recruit students and test out my own research ideas. I really want to be a good mentor for trainees, to offer them the support my mentors gave me.

I’m very passionate about tackling big challenges surrounding sustainability. It’s very inspiring to see so many like-minded young researchers, for example in your “Young PIs” series, who want to work on climate change and sustainability with their research. Let’s do it!


Ciarán was born in Dublin, Ireland. He graduated from the University of Glasgow in Scotland in 2007 with a BSc. (Hons) in Genetics. After a year of working at the Beatson Institute for Cancer Research in Glasgow, he went travelling for a year and a half before returning to start a PhD in the lab of Prof. Frank Sargent at the University of Dundee, Scotland. Following his PhD, he had postdoctoral positions at Oxford University, Imperial College London and Newcastle University. He recently started at Northumbria University in Newcastle as a Vice-Chancellor’s Fellow in Cellular and Molecular Biosciences. He’s a prolific tweeter and you can follow him and say hi @kellier13 on Twitter.

3 Questions for Dr. Yolanda Schaerli


In our latest post in our “3 Questions for” series, we have the joy to Interview Dr. Yolanda Schaerli. Yolanda is an assistant professor of synthetic biology at the University of Lausanne, Switzerland. Her research group uses synthetic biology to understand the mechanisms, properties, and evolution gene regulatory networks.


When and why did you move into the field of synthetic biology?

During my studies in biology, I became fascinated with engineering biological systems. The goal of my PhD project was to improve enzymes by directed evolution (performed in microfluidic water-in-oil droplets). When looking for a post-doc position, it was clear that I wanted to move into the emerging field of synthetic biology and decided to build synthetic gene regulatory networks. The research currently ongoing in my lab involves engineering synthetic constructs in E. coli that help us to understand underlying biological principles and fundamental properties of biological systems, with a focus on gene regulatory networks involved in pattern formation.


In which areas do see the main challenges and opportunities for synthetic biology?

Synthetic biology has the potential to fuel the next industrial revolution. Engineered biological systems have potential applications in almost every aspect of our lives, for example by providing novel approaches to detect and treat diseases and to produce fine chemicals, biofuels and smart materials, just to name a few. Synthetic biology will hopefully contribute to transition to a more sustainable society that avoids climate change and environmental degradation.

The big challenge is to realize this potential. This will require moving from “proof-of-principle” circuits to robust systems that reliable function in real-world settings. It will also require addressing ethical and regulatory issues.

 In basic science, synthetic biology provides us a complementary approach to study the mechanism, organization, function, and evolution of natural biological systems and processes. By building simplified versions of complex natural systems, we can focus on the elements of interest, while avoiding confounding factors. I hope that this approach will become more accepted and valued in the scientific community.


What is the most important piece of advice you would give to an early career researcher in synthetic biology?

I don’t think there is a single advice that applies to every early career researcher. I would like to mention three points that I think are important:

It is not enough to do great science; you also need to be able to communicate it. Good writing and presenting skills truly make a difference. If necessary, take some courses and practice as much as you can.

I often observe that PhD students and post-docs start too late thinking about what they would like to do next. If you only apply for post-doc positions after submitting your PhD thesis, you are likely to have an (unfinanced) gap, which might for example be problematic for your visa situation. Consider that it easily takes 10 months or more from applying to a fellowship or grant to starting the new position.

I would also like to point out that leaving academia is absolutely no failure and should be an option from the beginning. There are so many interesting jobs outside academia, why not considering them?

Young PIs in action: Interview with Stephen Wallace

In our next installment of our Young PI series, Jo Sadler interviews Stephen Wallace, group leader and lecturer at the University of Edinburgh.


Jo Sadler: How did you find your transition to PI? Any unexpected challenges?

Stephen Wallace: Goodness…how long do we have?! The entire process was scary, but an amazing amount of fun at the same time. I think most of the challenges I faced were somewhat unexpected – you are, after all, suddenly required to adapt to a job that requires a completely new set of skills. However, research is all about venturing into the unknown so perhaps the transition to PI is simply another manifestation of this. I found the isolationism of the job quite challenging at first – going from working with a group of people in a lab to working on my own in an office was a big change.

Luckily for me, the Institute for Academic Development at the University of Edinburgh runs a brilliant Research Leadership Program, which all new PIs are enrolled on. Also, I was fortunate to be selected for the 2017 Scottish Crucible, which was an invaluable opportunity for me to engage with the media, local government and to connect with other early-career researchers in Scotland. Both of these programs helped me tremendously during my first year as a PI.


Jo: Is E. coli the ideal environment to perform chemical reactions? What are the pros and cons of performing chemical synthesis within/associated with a cell?

Stephen: What an exciting question! To be honest, this is what we are exploring right now. One of the main challenges is their perceived incompatibility. Historically, the fields of chemical and biological synthesis have been considered as mutually incompatible – i.e. metal-based chemical catalysts are inactive under the conditions required to support a living organism and are toxic to cells. However, our research is showing that this is isn’t always true. For example, we’ve recently discovered a chemical reaction that is accelerated inside the membrane of living E. coli cells (it is, after all, similar to an organic solvent!). The potential for innovative research in this field is tremendously exciting and will continue to rely on the combined efforts of both synthetic biologists and synthetic chemists.

For now, all I can say for sure is that unexpected things keep happening when we try-out synthetic reactions in the presence of living cells, and these effects can often have a positive influence on the reaction outcome.


Jo:You have worked both in the UK and the US. Any striking cultural differences between the research environments? 

Stephen: Day-to-day life as a researcher in the UK/US is very similar. I’m always impressed by the “go get it!” attitude of American science, whereas I think British researchers tend to be more constrained and methodical (which isn’t necessarily a bad thing). This really inspired me during my time in Boston and LA and has certainly influenced my ethos as a PI in Edinburgh. In the absence of empirical data, the phrase “this won’t work” is banned in our lab.


Jo: Is mobility important for a researcher?

Stephen: I get asked this question a lot. Many scientists seem to believe that international experience is a prerequisite to a successful career in research. I strongly disagree with this mentality, but I do encourage my students explore options abroad when thinking about their next career move. I think it ultimately comes down to science and strategy (in that order) – where are the experts in your field? Where are the emerging techniques being developed, and can you bring something new/complementary to this field? I can always spot the scientists who move abroad simply to work for “the big name” and there’s often a downstream mono-dimensionality to their research as a result.


Jo: What is the one most important piece of advice you would give to a synthetic biology early career researcher?

Stephen: Never let an unexpected result go unexplained!
