BioDr. Brian Trippe is an assistant professor at Stanford in the Department of Statistics, with an affiliation in Stanford Data Science.
In his research, Dr. Trippe develops probabilistic machine learning methods to address challenges in biotechnology and medicine. Recently, his focus has been on generative modeling and inference algorithms for protein engineering.
Before joining Stanford, Dr. Trippe was a postdoctoral fellow at Columbia University in the Department of Statistics, and a visiting researcher at the Institute for Protein Design at the University of Washington. -
Barry Trost
Job and Gertrud Tamaki Professor in the School of Humanities and Sciences, Emeritus
BioBorn in Philadelphia, Pennsylvania, Barry Trost began his university training at the University of Pennsylvania (BA, 1962) and completed his Ph.D. in Chemistry at the Massachusetts Institute of Technology (1965). He moved directly to the University of Wisconsin, where he was promoted to Professor of Chemistry and subsequently Vilas Research Professor. He joined the faculty at Stanford as Professor of Chemistry in 1987 and became Tamaki Professor of Humanities and Sciences in 1990. In addition to serving multiple visiting professorships, Professor Trost was presented with a Docteur honoris causa of the Université Claude-Bernard (Lyon I), France, and in 1997 a Doctor Scientiarum Honoris Causa of the Technion, Haifa, Israel. In recognition of his innovations and scholarship in the field of organic synthesis, Professor Trost has received the ACS Award in Pure Chemistry, ACS Award for Creative Work in Synthetic Organic Chemistry, Arthur C. Cope Scholar Award, and the Presidential Green Chemistry Challenge Award, among many others. Professor Trost has been elected a Fellow of the American Academy of Arts and Sciences, American Chemical Society, and American Association for the Advancement of Science, and a member of the National Academy of Sciences, and served as Chairman of the NIH Medicinal Chemistry Study Section. He has held over 125 special university lectureships and presented over 270 Plenary Lectures at national and international meetings. He has published two books and over 950 scientific articles. He edited a major compendium entitled Comprehensive Organic Synthesis consisting of nine volumes and serves on the editorial board for Science of Synthesis and Reaxys.
The Trost Group’s research program revolves around the theme of synthesis, including target molecules with potential applications as novel catalysts, as well as antibiotic and antitumor therapies. The work comprises two major activities: 1) developing the tools, i.e., the reactions and reagents, and 2) creating the proper network of reactions to make complex targets readily available from simple starting materials.
Efforts to develop "chemists' enzymes" – non-peptidic transition metal based catalysts that can perform chemo-, regio-, diastereo-, and especially enantioselective reactions – focus close attention to the question of atom economy to minimize waste, energy, and consumption of raw materials.
Synthetic efficiency raises the question of metal catalyzed cycloadditions to rings other than six-membered. A general strategy is evolving for a "Diels-Alder" equivalent for formation of five, seven, nine, etc. membered carbo- and heterocyclic rings.
An exciting new direction derives from the molecular gymnastics acetylenes undergo in the presence of transition metals. Additional specific goals include cycloisomerization to virtually all types of ring sizes and systems with particularly versatile juxtaposition of functionality.
Palladium and ruthenium catalysts represent a major part of the lab's efforts, in order to invent new synthetic processes together with new opportunities for selectivity complementary to that obtained using other metal complexes. Main group chemistry, especially involving silicon, zinc, and sulfur, also offers many opportunities for new reaction design. Rational design of novel catalysts for asymmetric additions to carbonyl and imine groups are an exciting thrust.From these new synthetic tools evolve new synthetic strategies towards complex natural products. Targets include β-lactam antibiotics, ionophores, steroids and related compounds (e.g., Vitamin D metabolites), alkaloids, nucleosides, carbohydrates, and macrolide, terpenoid, and tetracyclic antitumor and antibiotic agents. -

Zhainib A. Amir
Ph.D. Student in Biology, admitted Autumn 2020
BioI received my B.S. in Microbiology, and M.S. in Cell and Molecular Biology from San Francisco State University. Currently, I am a Biology Ph.D. student with an emphasis in Cell, Molecular and Organismal Biology at Stanford University. I am interested in a range of topics, from cell biology to cancer immunology, however, my research interests lie primarily in understanding the cellular mechanisms at play in genetic and autoimmune diseases.

Andras Vasy
Robert Grimmett Professor of Mathematics
On Leave from 10/01/2025 To 06/30/2026Current Research and Scholarly InterestsMy research concentrates on topics in two broad areas of applications of microlocal analysis in which, partly with collaborators, I introduced new ideas in recent years: non-elliptic linear and non-linear partial differential equations (PDE), typically concerning wave propagation or other related phenomena, and inverse problems for X-ray type transforms along geodesics and related problems for determining the metric tensor from boundary measurements.

Juliana Velez-Gomez
Postdoctoral Scholar, Biology
BioJuliana Vélez (she/her) is a postdoctoral researcher with the Natural Capital Project, studying land-use change and vector-borne disease risk. Her research applies quantitative ecological methods to understand interactions among species, their habitat, and anthropogenic disturbance. Juliana's work incorporates ecological experimentation and collaborations with decision makers to assess the effectiveness of conservation actions for improving ecosystems. She conducts her research under open science standards and has contributed to the development of online resources for reproducible research, including the publication of guides, datasets, and code related to statistical modeling and data processing using artificial intelligence. Juliana earned her Ph.D. in Conservation Sciences from the University of Minnesota.
