As a graduate student at University of California, San Francisco, Jessica studied the genetic regulation of centrosome structure, function, and positioning and the mechanisms dictating internal cellular organization using the unicellular alga Chlamydomonas. She went on to characterize the role of the centrosome during epithelial polarization in C. elegans, working as a postdoctoral fellow at the Fred Hutchinson Cancer Research Center. She started her lab in the Stanford Biology Department in 2014. Her lab studies structural changes that occur at the cellular level during normal development and in disease. In particular, her lab is interested in understanding how microtubules become spatially organized in different cell types during cell differentiation.
