Past Internship Highlights

Contributed by Aiden Aceves (2018): During the summer of 2018 I spent three and a half months working as a data scientist in the structural biology group at The Genomics Institute of the Novartis Research Foundation (GNF). While GNF employs a team of data scientists as part of their informatics group, I was the first data scientist in the structural biology group. This granted me to opportunity to work closely with the Director of Structural Biology, a talented leader, structural biologist and programmer. My main task was the development and subsequent application of a framework for conducting machine learning on structural data. This was an exciting mandate, as I possessed excellent resources and mentoring, and was given the freedom to implement and test creative ideas. In addition to expanding my knowledge of machine learning, I learned about packaging, project structuring and documentation. Prior to this experience, most of the code that I had written was only for me. If someone else wanted to use, or even read it: good luck! Because the tools I wrote had to be usable on a variety of machines and by scientists with varying levels of computational experience it was critical that I developed better habits. Throughout the summer I met with the structural biology group regularly to train them to use the tools I developed. This process provided me with valuable feedback about software features and documentation to add, potential applications for the software, and how to communicate effectively. The work that I did was tremendously rewarding, and has spawned ongoing planning of a long-term collaboration. I am grateful that I was able to experience working at a medium-sized site like GNF, and among such driven and bright colleagues.

High rates of homologous recombination in yeast, coupled with an army of robots and custom software, make metabolic engineering at Amyris exceptionally rational and high-throughput. So far, this pipeline has generated yeast strains that produce farnesene (a precursor to many other useful molecules) and squalane oil (which forms the basis for their direct-to-consumer skincare) at the kilogram scale.

For my project, I explored how a relatively simple but ad hoc step in the engineering pipeline could be automated with Amyris’s existing technology. Working on something very different from my thesis, I discovered (and partially filled) gaps in my knowledge of yeast and chemistry, but also took stock of my core set of skills that apply to any scientific problem: problem definition, experimental design, and data analysis. What I most enjoyed was mapping certain quantitative features of the biology onto clear boundaries for success for different automated solutions. 

Overall, the most meaningful part of this experience was meeting PhD-level scientists who said working at Amyris satisfied all their scientific goals. It made me consider how a scientist selects their career goals, which I discovered are surprisingly similar between an academic PI and industrial project manager. Each sets a scientific trajectory toward a hard goal require cutting-edge technology and knowledge we don’t have yet, maneuvers the confines of available money and resources, manages teams of scientists to carry out this work as various team members see fit, and knows the majority of their success comes down to careful written and oral communication of their work to their scientific community. The key differences are how you pick the scientific trajectory (though each are subject to certain unglamorous boundaries in their planning) and the values and composition of that scientific community. Ultimately, I enjoyed Amyris for many of the reasons I enjoy Caltech: inspiring scientific problems and generous, creative coworkers.

Contributed by Anu Lakshmanan (2018): During the summer of 2018, I had the unique opportunity of doing a research internship at Synlogic, Inc. in Cambridge, Massachusetts. Compared to conventional drugs based on synthetic chemicals, Synlogic is pioneering the development of a novel class of ‘living medicines’ or ‘Synthetic Biotics’ by using synthetic biology principles to genetically re-program beneficial probiotic bacteria. While at Synlogic, I closely worked with the Microbial Engineering and Discovery Sciences (MEDS) team to design and build new probiotic strains, as well as test newly built strains for desirable functionalities that would expand and optimize future versions of Synlogic’s clinical candidates. I was fortunate to be involved in multiple projects at different stages of development: from genetically engineering probiotic therapeutics for new disease targets to downstream characterization of clinical drug candidates. This enabled me to collaborate and work with scientists from many other groups such as Bioanalytics, In Vivo Pharmacology, Process Development and Manufacturing Sciences. The experience gave me valuable insight into the processes involved in translating an innovative scientific idea into a therapeutic product that could benefit patients. 

This was my first foray into research outside academia and while I was excited to see how R&D was carried out in the corporate biotech space, I had some reservations about how I would fit into the industry culture and whether I would have the scientific freedom to explore and implement new ideas as an intern. However, my fears were put to rest during the very first week of my internship when my manager at Synlogic encouraged me to discuss and implement new, relevant project ideas during my time there. Besides contributing to several ongoing high-impact projects, I was also able to work on an independent pilot project to generate useful data for the company. While putting my previous research skills and experience to good use, I also got valuable exposure to cutting-edge tools and techniques currently used in synthetic biology and drug development. At the end of my internship, I presented my research findings and conclusions to a large team of senior researchers and team leaders including the CSO, which was very well-received. 

I consider my internship at Synlogic to be a valuable and enriching learning experience that opened my eyes to exciting research opportunities outside the academic setting. It was especially satisfying to see the direct application of my research to create and/or improve a therapeutic with the potential to alleviate patient suffering. I am extremely grateful to the Biotechnology Leadership Program at Caltech and Synlogic for giving me this opportunity to do an industrial internship, and even wish that I had done this earlier in my PhD program. Based on my experience, I would highly recommend all students to consider doing an industrial internship during graduate school to gain exposure to different R&D pipelines outside academia. Last but not the least, I strongly believe that the industrial experience will help me make a more informed decision about my next step after graduate school and allow me to actively explore new ways in which I can contribute to improving human lives through biomedical research.

Contributed by Pradeep Ramesh (2018): This summer, I had the pleasure of interning at EvoRx Technologies Inc, a small start-up in Pasadena, CA, which focuses on evolving cyclic-peptides that can either activate or inactivate specific biochemical pathways within the cell. Given my broader interest in starting a company down the road, I felt that working at a small startup would offer insight into the funding and management challenges of an early stage venture. In addition, I chose this company in order to learn about a topic that I am interested in pursuing during my post-doctoral studies. Although my background in physics and bioengineering was quite different from those of the scientists currently employed by the company, I was nonetheless able to contribute in a unique way.

My main project consisted of developing new biochemical assays to interrogate the efficacy of evolved cyclic peptides – in practice, this meant (a) applying my knowledge of molecular biology to build and purify protein constructs which would then serve as test platforms and (b) learning solid-phase peptide synthesis in order to synthesize new variants of successful compounds. While learning about the company’s design-build-test pipeline, I observed that one of the rate limiting steps in the process was whether or not the evolved compound could successfully cross the cell membrane. I realized that this problem could perhaps be tackled using Machine Learning, since the rules for cell-uptake are reasonably well understood. Consequently, using data on cell-potency for compound variants, I set out to build an ML algorithm that could learn from the data and thereby predict the cell-permeability of new variants. While I was not able to complete this work within the timeframe of the internship, I was happy to introduce a new concept to the company, which may prove to be useful in the near future. 

Beyond the intellectual challenges, I enjoyed getting to know my co-workers. Since the company has 6 employees, I was able to connect with other colleagues on both a personal and professional level. I thoroughly enjoyed my conversations with them, and found it helpful to glean a new reduction to practice mindset, which substantiates the decision making process within the company. It was here that I learned about the practical challenges that guide and influence medicinal chemistry and drug discovery. It was also here that I learned about how funding is acquired and how individuals have to balance many roles simultaneously. I enjoyed my experience and would strongly recommend others to explore this and other startups. 

Contributed by Ruijie (Kelly) Zhang (2018): This summer I was an intern with the Biology Department at Amryis, in Emeryville, CA. Amyris is a synthetic biology company whose platform is to use designer yeast to transform sugar into value added products. The Biology Department, the research arm of Amyris, is responsible for creating strains of engineered yeast which produce the desired molecules. Automation plays a huge role at Amyris, which relieves the scientists of many mundane tasks so they have more time for design. With strong internal collaborations across departments, this talented team of scientists and their army of robots can accomplish metabolic engineering goals incredibly quickly. 

During my time as an intern, I worked with a team of scientists to create a strain of yeast with improved efficiency for the production of a target molecule. Working on something very different than my PhD project allowed me to appreciate an entirely new field of science. As an experimentalist, I learned to translate what I learned about designing experiments for my PhD project to a different system.  This experience in industry has taught me many lessons about project management. Working together with a team to achieve a common goal requires team members to break down a problem into discreet sections and deliver the results of these sections on the agreed timeline— useful lessons that I will apply my future work!

Amyris is an exceptional company to intern for. The scientists who work there are extremely passionate about science and work hard to foster a positive environment. I met many scientists there whom I greatly respect and I believe this company will lead the way in using microorganisms for the green production of chemicals.

During this experience, I was able to apply the technical skill set I learned at Caltech while cultivating new expertise in genomics, data analytics and software evaluation. In addition to programming projects, I also had the unique opportunity to participate in two smaller business development projects. I finished the internship as a better bioinformatician and with a better sense of the commercial medical diagnostics market. 

In addition to being a great learning experience, the internship was also fantastic as a networking opportunity. Throughout the summer, I had the pleasure of sitting in on talks by senior company leaders where I learned about their career path and their current function at the company. To take it one-step further, Roche also actively encourages the interns to branch out and network throughout the company. By taking advantage of these opportunities, I was able to connect with many scientists who transitioned to business development, marketing and other roles that are away from the bench while still utilizing their scientific training.   

In summary, I found my internship to be a great learning experience as well as a fantastic networking opportunity. It was satisfying to be able to apply my technical background on several development projects while also appreciate the fact that many previous bench scientists were able to transition to meaning roles in the industry. Personally, this internship expanded my view of research in the industry and I highly encourage other students to take similar opportunities to explore their career interests.  

Contributed by: Kevin Yang (2017): During the summer of 2017, I was a computational intern in the bioinformatics department at Ambry Genetics in Aliso Viejo, California. Ambry Genetics is a genetic testing and diagnostics company that develops, manufactures, distributes, and interprets genetic tests. At Ambry, I worked with a structural biologist and statistical geneticist to develop predictive models for human genetic variation. As part of this work, I applied many ideas and computational skills I learned at Caltech while also learning new techniques as needed for my project. Working with patient data also introduces privacy issues, and I saw how Ambry strives to balance patient privacy with a belief in open data.

Compared to academic research, research at Ambry was much more focused. Generally, scientists there were focused on helping interpret specific cases or on building the scientific and technical framework to make more accurate or novel tests. Many of the scientists there were motivated by seeing their results used directly to help patients, which is much rarer in the academic setting.

I am grateful to Ambry Genetics and to the Biotechnology Leadership program for the opportunity to work at Ambry. As decisions about my post-PhD career approach, the experience doing research in a commercial environment will help me to make a better-informed decision about the type of work I want to do and where I want to do it.

Contributed by: Josh Brake (2016): This past summer I had the opportunity to intern for Instrumentation Laboratory, a medical device company headquartered in Bedford, MA. Instrumentation Laboratory has two main diagnostic product lines: hemostasis analyzers which assess the clotting properties of blood and critical care analyzers used at the point-of-care in hospital emergency rooms to quickly analyze blood samples and determine the levels of key analytes and diagnostic markers. While I was there, I worked with a group of R&D engineers on the development of some new ideas for optical detection in their next generation critical care analyzers. As part of this team, I had the chance to work closely with several of the engineers and learned about blood diagnostics and the optical techniques they use in their current devices. Additionally, I got to see and work to solve some of the engineering challenges that need to be addressed to improve future generations of the product. I particularly enjoyed the chance to see how research is done outside of the academic setting of my research lab at Caltech. The experience of an internship as a PhD student is rewarding and one I would recommend for all graduate students. Even though I am interested in pursuing a career in academia at this point in my studies, understanding the constraints on research and product design methodologies in a commercial setting is a valuable asset for framing research questions in a practical and compelling way. This experience taught me to think critically about simplifying and distilling devices so that they are reliable, easily made at scale, and cost efficient. These skills have translated back into the lab, helping to hone my entrepreneurial thinking and to elucidate the right questions to ask when translating technologies from the lab to real world practical applications. I am grateful to Instrumentation Laboratory for the chance to work for them this summer and also for the Biotechnology Leadership Program at Caltech which provided me with the opportunity and support to explore this opportunity. The experience was a valuable one for me, and I hope that other PhD students will consider taking an internship during their studies to explore potentially fulfilling career opportunities outside of the typical academic track. I suspect that you’ll learn, like I did, a lot of valuable lessons!
