Prashant’s interest in pursuing a physician-scientist pathway originated from his undergraduate research experience in Dr. Jennifer Doudna’s RNA biochemistry laboratory at UC Berkeley. During his time there, the lab discovered the biological function of an RNA-mediated enzyme called Cas9 that can be engineered to correct mutations in DNA occurring in human cells. His project focused on the fundamental biology underlying Cascade-Cas3, a complex related to Cas9. 

His current research interests stem directly from patient encounters during medical school where he learned that many patients with cancer, cutaneous disease, or other diseases corresponding to aberrant transcription – have a wide array of mutations in the non-coding regions of their genomes. Furthermore, the nucleus is spatially organized such that DNA, RNA, and protein molecules involved in shared functional and regulatory processes are compartmentalized in three-dimensional (3D) structures. These structures are emerging as a paradigm for gene regulation, a highly complex process that requires the dynamic coordination of hundreds of regulatory factors around precise targets in different cell states. He has contributed to development of a novel method called Split Pool Recognition of Interactions by Tag Extension (SPRITE) that generates high-resolution global maps of RNA and DNA interactions (Quinodoz et al Cell 2018, Quinodoz, Bhat et al Cell 2021, Quinodoz, Bhat et al Nature Protocols 2021), which generated a view of nuclear organization around several essential nuclear functions.

Science and health policy/public outreach

Prashant’s training and experience has also involved exploring the intersection between science, policy, and the public. He was Editor-in-Chief of Berkeley Scientific Journal and a science writer for PLoS before starting medical school. In addition to science writing, he is interested in shaping policy decisions by advocating for continued federal funding of basic science research. To that end, he has participated in face-to-face discussions with advocates and politicians directly involved in policy decisions at the federal level through his involvement in science policy programs in Washington DC and the Dr. Lucy Jones Center for Science and Society. Additionally, he led the LGBTQ+ group at the Caltech Center for Inclusion and Diversity, where he organized social and outreach events to improve all facets of LGBTQ+ life.
