Jude Wolf

Hi! My name is Jude (he/him), and I am a sophomore majoring in Biology and Art Practice. I am pre-med and from Denver, Colorado. Aside from being passionate about sharing my love of chemistry, I enjoy the arts (mainly film and photography), getting outside, trying new food, and fostering senior dogs. Coming to Stanford from a large public high school with no chemistry background was intimidating at first– but STEMentors showed me that everyone has the ability to succeed, and you are never alone in the transition.

I completed the requirements for the chemistry major in two years, so I am eager to help with course selection and planning. Additionally, I love exploring new cultures and places, and as an international student from Russia, I'm eager to discuss Russian Literature. Outside of academics, I serve as a president of a Russian-speaking student organization where we host cultural and networking events.


Professor Robert Waymouth - Faculty Lead, Co-founder

Robert Eckles Swain Professor in Chemistry Robert Waymouth investigates new catalytic strategies to create useful new molecules, including bioactive polymers, synthetic fuels, and sustainable plastics. In one such breakthrough, Professor Waymouth and Professor Wender developed a new class of gene delivery agents.Born in 1960 in Warner Robins, Georgia, Robert Waymouth studied chemistry and mathematics at Washington and Lee University in Lexington, Virginia (B.S. and B.A., respectively, both summa cum laude, 1982). He developed an interest in synthetic and mechanistic organometallic chemistry during his doctoral studies in chemistry at the California Institute of Technology under Professor R.H. Grubbs (Ph.D., 1987). His postdoctoral research with Professor Piero Pino at the Institut fur Polymere, ETH Zurich, Switzerland, focused on catalytic hydrogenation with chiral metallocene catalysts. He joined the Stanford University faculty as assistant professor in 1988, becoming full professor in 1997 and in 2000 the Robert Eckles Swain Professor of Chemistry. Today, the Waymouth Group applies mechanistic principles to develop new concepts in catalysis, with particular focus on the development of organometallic and organic catalysts for the synthesis of complex macromolecular architectures. Professor Waymouth is an instructor for CHEM 31A: Chemical Principles I, the first course in Stanford's introductory chemistry sequence.
