Research Summary

The goals of my research build directly on research that I began as a postdoctoral fellow in Allan Spradling’s lab at the Carnegie Institution, and have continued in my own lab over the past six years. More generally, my education and training have given me valuable skills for succeeding in basic science. As a graduate student with Mark Roth at the Fred Hutchinson Cancer Research Center, I learned to identify and develop concepts that were both innovative and medically relevant. Early in my graduate studies, we discovered suspended animation in C. elegans (Nystul, et al., Science, 2003), and my characterization of this phenomenon was a critical part of a team effort that led to several patents and the founding of Ikaria, Inc., a multi-national biomedical research company. Subsequently, as a postdoctoral fellow at the Carnegie Institution, I gained a better understanding of the importance of thinking broadly and studying multiple model organisms in developing productive research projects. I have been implementing these skills as I mentor the people in my lab and build our research program. At UCSF, I have the benefit of a rigorous, collegial scientific community, and a commitment of support from colleagues, such as my faculty mentors Drs. Zena Werb, Susan Fisher, and Diane Barber.
