April 15, 2025 | In this episode of The Chain, host Brandon DeKosky, associate professor, speaks with MIT colleague Jessica Stark, Underwood-Prescott career development professor, about glycans and why they are important in cancer research. Stark discusses how she became interested in immunology, what her PhD and post-doctoral training was like, her thoughts on singlets operating as part of a network of checkpoint molecules, and what’s currently going on in glycobiology. She also talks about her keynote presentation at PEGS 2025 and what her new lab is working on.

GUEST BIO

Jessica C. Stark, PhD, Underwood-Prescott Career Development Professor, MIT
Jessica Stark is an Assistant Professor in the departments of Biological Engineering and Chemical Engineering at MIT and an intramural member of the Koch Institute for Integrative Cancer Research. The Stark Lab is developing biological technologies to realize the largely untapped potential of glycans for immunological discovery and immunotherapy. As an American Cancer Society Postdoctoral Fellow with Prof. Carolyn Bertozzi at Stanford University, Jessica’s work focused on identifying and targeting glycans that act as immune checkpoints for next-generation cancer immunotherapy. As an NSF Graduate Research Fellow with Prof. Michael Jewett at Northwestern University, Jessica developed cell-free technologies for protein therapeutic and vaccine production that promise to enable portable and personalized medicine. Previously, she received her B.S. in Chemical and Biomolecular Engineering from Cornell University and worked at Genentech, Inc. in process development and research and development roles. Jessica’s independent work has been recognized with a Burroughs Wellcome Fund Career Award at the Scientific Interface, the Society for Immunotherapy of Cancer’s Steven A. Rosenberg Scholar Award, and a V Foundation V Scholar Award. The Stark lab is committed to enhancing diversity, equity, and inclusion in STEM through mentoring, outreach, and service activities. To support this work, Jessica co-developed and commercialized BioBits educational kits that promise to increase access to high-quality biology education by facilitating hands-on learning.

MODERATOR BIO

Brandon DeKosky, Associate Professor, MIT
Brandon J. DeKosky joined the Department of Chemical Engineering as an assistant professor in a newly introduced joint faculty position between the department and the Ragon Institute of MGH, MIT and Harvard in September 2021. He received his BS in chemical engineering from University of Kansas, and his PhD in chemical engineering from the University of Texas at Austin. He then did postdoctoral research at the Vaccine Research Center of the National Institute of Infectious Diseases. In 2017, Brandon launched his independent academic career as an assistant professor at the University of Kansas in a joint position with the Department of Chemical Engineering and the Department of Pharmaceutical Chemistry. He was also a member of the bioengineering graduate program. His research program focuses on developing and applying a suite of new high-throughput experimental and computational platforms for molecular analysis of adaptive immune responses, and to accelerate precision drug discovery. He has received several notable recognitions, which include receipt of the NIH K99 Path to Independence and NIH DP5 Early Independence Award, the Cellular and Molecular Bioengineering Rising Star Award from the Biomedical Engineering Society, and the Career Development Award from the Congressionally Directed Medical Research Program’s Peer Reviewed Cancer Research Program.
