Associate Professor of Physics
SLAC National Accelerator Laboratory
Risa Wechsler is an Associate Professor of Physics at Stanford and at the SLAC National Accelerator Laboratory, where she has been a faculty member and a member of the Kavli Institute for Particle Astrophysics and Cosmology since 2006. She is a cosmologist who studies the evolution and contents of the Universe from its earliest moments to the present day using large numerical simulations and data from surveys of hundreds of millions of galaxies. Her work uses a wide range of statistical and computational tools to make use of the largest existing cosmological simulations and the largest galaxy surveys that are being pursued to learn about the nature of dark energy and dark matter and the physics of galaxy formation.
