Before joining the 10x Genomics Cell Biology and Applications team I was an NIH Ruth L. Kirschstein National Research Service Award (NRSA) fellow at USC Stem Cell in the laboratory of Andrew P. McMahon. I investigated comparative developmental biology of the mouse and human kidney with a focus on how the body's primary filter is established by nephron, interstitial, and endothelial progenitors leveraging insights identified from single cell genomic analysis in collaboration with Kun Zhang's laboratory at UCSD. I utilized high resolution microscopy and high throughput cell-based assays to identify genetically and chemically tractable signaling pathways for regulation of these coordinated processes. The developmental biology of vertebrate organs has been my career-long focus shaped from my graduate studies in the laboratory of David Traver at UCSD. My goals at 10x Genomics are to expand the resolution and the applicability of single cell and spatial genomics methods to derive more complete insights for biology and personalized medicine. Before I used to think about the biology of a village of cells of one organ at a time and now I need to consider how researchers will mine the universe of biological specimens in their current research needs but also needs that they haven't thought of yet.
