Risa Wechsler
Director, Kavli Institute for Particle Astrophysics and Cosmology (KIPAC), Humanities and Sciences Professor and Professor of Physics and of Particle Physics and Astrophysics
BioRisa Wechsler is the Humanities and Sciences Professor and the Director of the Kavli Institute of Particle Astrophysics and Cosmology. She is also Professor of Physics (H&S) and Professor of Particle Physics & Astrophysics (SLAC), Director of the Center for Decoding the Universe, and an Associate Director at Stanford Data Science. She is a cosmologist whose work investigates some of the biggest outstanding questions about our universe — how it formed, what it is made of, how it is structured, and what its future holds.
Her research focuses on understanding the evolution of galaxies, the large-scale structure of the universe, and the nature of dark matter and dark energy. She uses large numerical simulations, theoretical models, and the largest observed maps of the universe to explore these forces that shape the cosmos. Her recent work also investigates the formation and cosmological context of the Milky Way and probes dark matter through small-scale cosmic structure, and explores how data science and AI/ML can drive new understanding. Wechsler has played key leadership roles in major international collaborations including the Dark Energy Survey, Dark Energy Spectroscopic Instrument, and Rubin Observatory's Legacy Survey of Space and time, a decade-long survey that will reveal the dynamic universe in unprecedented detail. She is recently involved in the Via Survey, which will map the Milky Way at high precision to probe dark matter physics in new ways.
Wechsler is an elected member of the National Academy of Sciences and the American Academy of Arts and Sciences and a Fellow of the American Physical Society and the American Association for the Advancement of Science.

Ralph Wedgwood
Fellow, CASBS
BioRalph Wedgwood is Professor of Philosophy at the University of Southern California. In 2025-26, he is visiting Stanford as Andrew W. Mellon Foundation Fellow at CASBS (the Center for Advanced Study in the Behavioral Sciences). He works on epistemology and ethics (including metaethics, formal ethics, rational choice, normative ethical theory, and the history of ethics). He is the author of "The Nature of Normativity" (Oxford, 2007), "The Value of Rationality" (Oxford, 2017), and "Rationality and Belief" (Oxford, 2023), as well as more than 65 articles in journals and edited volumes.
