Biography

After completing my PhD, on the molecular pathology of breast tumors, I joined Dr. Mary-Claire King’s laboratory at the University of Washington as a postdoctoral fellow to study inherited predisposition to breast cancer.  I joined the Division of Medical Genetics in 2005 and took advantage of resources here to learn genomics technology.  This experience led me to develop a massively parallel sequencing resource for my collaborative work.  I was among the first to exploit exome sequencing to discover new genes for Mendelian diseases and to demonstrate de novo mutations are involved in schizophrenia.  In collaboration with clinical colleagues, I have helped develop and implement gene panel testing for breast, ovarian and colon cancer susceptibility at the University of Washington.
