Biophysics uses physical methods to study biological systems and the field can be broadly divided into three main fields: molecular, cellular, and systems biophysics.
At Berkeley, molecular biophysicists detect and manipulate single molecules to elucidate molecular motors, protein folding, polymer (biopolymer) physics, single molecule rheology, dynamics of complex processes such as transcription, replication, translation, etc. Cellular biophysicists look at molecular mechanisms of channel gating, the design and building of alternative chemical network wiring inside cells, the imaging of fundamental cell processes, and they create computational models of cellular metabolic control and molecular switches.
The field of systems biophysics, also represented in the Physics Department at Berkeley, aims at describing collective phenomena and addresses evolutionary and ecological dynamics of populations, biofilm development, sensory studies, neural development, synapse organization, neural transmission, as well as the functional imaging of the brain and spatio-temporal coordination of movement.
Carlos Bustamante received his B.S. in 1973 from Universidad Peruana Cayatano Heredia; M.S. in 1975 from Universidad Nacional Mayor de San Marcos; Ph.D.
Fifty years ago, biochemists described cells as small vessels that contain a complex mixture of chemical species undergoing reactions through diffusion and random collision.
Michael DeWeese received his BA (1988) in physics from the University of California at Santa Cruz and his PhD (1995) in physics from Princeton University.
Having to focus on one voice in a crowded room of boisterous speakers is a common experience for most of us, and we humans are extremely good at it, yet the latest algorithms running on the fastest modern computers fail miserably at isolating a single voice from a noisy background in all but the
Ahmet Yildiz received his Ph.D. in biophysics at University of Illinois Urbana-Champaign in 2004. During his Ph.D., he developed a single fluorescent particle tracking method with one-nanometer accuracy and showed how molecular motors of cytoskeleton walk along linear tracks inside cells.
Yildiz laboratory combines molecular biology and biophysical techniques to understand mechanisms that underlie the cellular organization and motility.
