Kathleen (Katie) Sicinski
I received my PhD in Chemistry from Tufts University in 2021. My thesis focused on developing novel chemical methods to enhance the metabolic stability of therapeutic peptides in the GLP-1 peptide family, which includes hormones like Ozempic. This work resulted in a start-up company Velum, Inc founded by my PhD advisor Prof. Krishna Kumar. During my PhD, I had the privilege of representing Velum at the Tufts University $100k New Ventures Competition, where we secured 3rd place. After my PhD, I worked as a scientist for a start-up biotech company, PepGen, Inc. At PepGen, I saw the company go from series C fundraising to its initial public offering in 2022 and advanced into clinical trials for the treatment of Duchenne muscular dystrophy. I was responsible for transitioning laboratory operations from Oxford, UK to Boston, MA and discovering new bioconjugation methods for delivery of therapeutic oligonucleotides into target cells. I then moved in 2022 to my current position at California Institute of Technology as a NIH Ruth L. Kirschstein NRSA Postdoctoral Fellow in the lab of Prof. Frances Arnold. In my current position, I utilize the powerful tools of directed evolution for protein engineering and apply machine learning methods to accelerate wet-lab discoveries. This is where I met my current co-founder, Ravi Lal. We have been working together to fast-track the iterative process of protein engineering by incorporating machine learning and high throughput analytical tools to deliver sustainable biocatalysts for the synthesis of molecules.
My current work in the Arnold lab focuses on evolving and engineering enzymes to transform low-cost chemical feedstocks into a variety of valuable synthetic building blocks. Throughout my project, I have streamlined the protein engineering process by integrating machine learning methods, enabling faster evolution of biocatalysts while reducing resource consumption. My ultimate vision is to see biocatalysts become the standard in chemical synthesis. I aim to make these engineered enzymes more accessible so that chemists can easily transition to greener, more sustainable alternatives to traditional chemical synthesis.
