Andreas Albrecht is a leading theoretical cosmologist. He received his Ph.D. from the University of Pennsylvania in 1983 where, with Paul Steinhardt, he wrote one of the original papers on “new” or “slow roll” inflation. Slow roll inflation has since become the dominant theory of the early universe and has passed numerous observational tests with flying colors. Deep puzzles remain regarding the theoretical underpinnings of cosmic inflation and Albrecht is a leading figure in this research area. The discovery of cosmic acceleration (often referred to as “the dark energy”) has been transformative to the field of cosmology and Albrecht is known for his groundbreaking work on dark energy theory and phenomenology. Albrecht moved from a professorship at Imperial College to UC Davis in 1998 to build the cosmology program there. He is now physics department chair at UC Davis. He is a fellow of both the American Physical Society and the Institute of Physics.
