Dr. Katherine A. (Kate) Rauen is a physician-scientist and Professor Emeritus in the Department of Pediatrics, Division of Genomic Medicine at the University of California Davis. She received a Master of Science in Human Physiology and a PhD in Genetics from UC Davis doing research on gene dosage compensation and genetic evolution. She obtained her Medical Degree at the University of California Irvine where she also did research in cancer genetics. Dr. Rauen did her residency training in Pediatrics and fellowship training in Medical Genetics at the University of California San Francisco. Dr. Rauen is internationally known for her pioneering work in the early application of microarray technology in clinical genetics and as a leader and major contributor to the understanding of RASopathies, genetics syndromes of the RAS/MAPK pathway. Her research program involves the clinical and basic science study of cancer syndromes with effort to identify underlying genetic abnormalities affecting common developmental and cancer pathways.
