Dr. Greenwood received her B.S. in molecular biology from the University of California, San Diego and subsequently earned her Ph.D. from the Biomedical Sciences Program of the UCSD in 2002 with a specialization in Psychiatric Genetics. As a Project Scientist in the Department of Psychiatry at UCSD, she augmented her molecular genetics background with training in applied statistical genetics methodologies under the supervision of Dr. Nicholas Schork. Dr. Greenwood joined the faculty at UCSD in 2007. She is currently an Assistant Adjunct Professor in the Department of Psychiatry and the Associate Chief of the Genetics and Genomics Unit of the San Diego VA Center of Excellence for Stress and Mental Health (CESAMH).

Research Focus 
Dr. Greenwood’s research focuses on genetic linkage and association studies and candidate gene analyses for psychiatric disorders. In this capacity, she currently participates in a number of large-scale collaborations, including the NIMH Bipolar Genetics Study (BiGS), which is funded to conduct genome-wide association studies of bipolar disorder, and the Consortium on the Genetics of Schizophrenia (COGS), which is funded to assess the contribution of endophenotypic measures to schizophrenia susceptibility and outcome. Through her involvement in the Genetics and Genomics Unit of the Center of Excellence for Stress and Mental Health (CESAMH), she is pursuing genetic strategies for identifying the predisposing determinants of susceptibility to post-traumatic stress disorder (PTSD).
