I am a Research Assistant Professor in Microbiology at the University of Washington, and an Affiliate Scientist at the Los Alamos National Laboratory. I currently work at the Northwest Regional Center for Excellence on topics relating to bacterial pathogenesis and innate immunity. Earlier, I was a principal investigator in the Biosecurity and Public Health Group in the Biosciences Division at Los Alamos National Laboratory (2002-2011).
I received my Ph.D. in Bio-organic Chemistry from SUNY-Stony Brook in 1997 under the guidance of Dr. Glenn D. Prestwich in synthesis and biochemical characterization of photoactivatable analogs of phosphatidylinositol polyphosphates. Subsequently, from 1997-1999, I pursued postdoctoral studies in Cell Biology at Harvard Medical School in the laboratory of Dr. Joan S. Brugge, developing modified nucleotide analogs and engineered kinases in order to identify direct substrates of protein kinase Akt. In parallel, I studied integrin-mediated cell signaling and identified a role for protein kinase Pak in phosphatidylinositol 3’- kinase mediated Raf signaling. I joined the Fred Hutchinson Cancer Research Center as a postdoctoral associate in Dr. Jonathan A. Cooper’s laboratory in 1999 and continued to employ chemical methods to probe direct substrates of tyrosine kinase c-Src. From 2001-2002, I was a Staff Scientist at the Metabolic and Respiratory Diseases Group in Wyeth Research, Cambridge and worked on developing assays for high throughput screening of protein kinase C isoforms.
