Hi there! I'm a postdoc at UC Davis studying mitochondrial genome inheritance.

About

I am currently a postdoctoral fellow in the laboratory of Distinguished Professor Jodi Nunnari at the University of California, Davis, where I use basic and systems cell biology approaches to interrogate the mechanisms of mitochondrial genome synthesis, segregation and inheritance in mammalian cells. In January 2020 I will join the Department of Molecular and Cell Biology at UC Berkeley, as an Assistant Professor of Cell and Developmental Biology.
