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 and Professor of Particle Physics & Astrophysics at SLAC National Laboratory, 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 most profound 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.

Paul B. Welander
Lead Scientist, SLAC National Accelerator Laboratory
BioPaul Welander is a Lead Scientist and Head of the Quantum Devices Department in the Technology Innovation Directorate at SLAC National Accelerator Laboratory. Paul’s research interests concern materials for quantum devices, from the study of materials-induced decoherence mechanisms in superconducting quantum bits, to the development of materials platforms that enable novel quantum technologies. He’s a researcher in both the Detector Microfabrication Facility and Nano-X, two new state-of-the-art cleanrooms at SLAC geared toward superconductor quantum device fabrication and rapid nano-prototyping, respectively. Paul also leads experiments at the Stanford Synchrotron Radiation Lightsource (SSRL) to characterize materials used in superconducting quantum devices and correlate those measurements with device performance and quantum decoherence rates. His expertise includes molecular beam epitaxy of metal-oxide heterostructures, superconducting device fabrication, and an array of materials characterization techniques including electron and x-ray diffraction, photoelectron spectroscopy, and scanning probe microscopy. Paul received his Ph.D. in physics from the University of Illinois at Urbana-Champaign, and holds Bachelors degrees from both Caltech and Occidental College. Prior to joining SLAC in 2012, he spent five years as a member of the technical staff at MIT Lincoln Laboratory.
