    Professor of Cell and Developmental Biology

    I obtained my Ph.D at Harvard Medical School with Frank Mckeon, and performed postdoctoral work at the EMBL in Heidelberg with Eric Karsenti. I started my lab at UC Berkeley in 1998, and my research interests are cell division and biological size control.

Topic

Mechanisms of mitosis and size control in Xenopus

To mediate chromosome segregation during cell division, the microtubule-based spindle adapts to changes in cell size and shape, which vary dramatically across species and within a multicellular organism. We take advantage of cytoplasmic extracts prepared from eggs of different sized frogs to study mechanisms of spindle and nuclear size control that vary among species, as well as extracts prepared from embryos at different stages to study size scaling that occurs during early development. Our studies aim to reveal underlying principles of spindle assembly and biological size control, as well as the molecular basis of variation that contributes to genomic instability and evolution. 

Audience

Free and open to the university community and the public.
