Roger Freedman


Dr. Roger A. Freedman is a Lecturer in Physics at the University of California, Santa Barbara.

He was an undergraduate at the University of California campuses in San Diego and Los Angeles, and did his doctoral research in theoretical nuclear physics at Stanford University. He came to UCSB in 1981 after three years of teaching and doing research at the University of Washington. At UCSB, Dr. Freedman has taught in both the Department of Physics and the College of Creative Studies, a branch of the university intended for highly gifted and motivated undergraduates. In recent years, he has helped to develop computer-based tools for learning introductory physics and astronomy and has been a pioneer in the use of classroom response systems and the “flipped” classroom model at UCSB. Roger holds a commercial pilot’s license and was an early organizer of the San Diego Comic-Con, now the world’s largest popular culture convention.

Robert Geller


Robert M. Geller teaches and conducts research in astrophysics at the University of California, Santa Barbara, where he also obtained his Ph.D.

His doctoral research was in observational cosmology under Professor Robert Antonucci. Using data from the Hubble Space Telescope, he is currently involved in a search for bursts of light that are predicted to occur when a supermassive black hole consumes a star. His other project, in biomedicine,
explores the use of magnetotactic bacteria to enhance the effectiveness of radiation therapy in treating cancer. Dr. Geller also has a strong emphasis on education, and he received the Distinguished Teaching Award at UCSB in 2003.

His hobbies include rock climbing, and he built an unusual telescope
with lenses made of water.
