Dolores Božović

Dolores Bozovic received her PhD in Physics in 2001, from Harvard University, on electron transport in carbon nanotubes. She then completed postdoctoral training at Rockefeller University, from 2001-2005, in a Sensory Neuroscience laboratory. From 2005 to the present, she was Assistant and then Associate Professor at the Department of Physics and Astronomy and the California NanoSystems Institute, at University of California Los Angeles.

The Bozovic lab focuses on problems at the interface between physics and sensory neuroscience. In particular, we study how auditory and vestibular systems perform mechanical sensing down to the nanometer level. The main topics are: (1) nonlinear dynamics of response by individual elements - the hair cells, (2) synchronization of movement by inter-cell coupling, and (3) self-tuning in response to external stimulus. The experiments require measuring bundle motility with nanometer-level precision, in preparations that preserve the biological function of the cells. Our measurement system includes parallel-tracking ability, allowing us to explore synchronization between active motility of different hair cells. We interpret our findings in the context of nonlinear dynamics and bifurcation theory, to explain the nanoscale sensitivity displayed by the biological system.
