Patrick Cahan grew up in St. Louis, MO. He received a B.S. in Computer Science from University of Maryland, Baltimore County, where he got his first research experience working on Information Retrieval systems. While working in Chile as a programmer, Patrick became interested in Computational Biology and returned to the US to pursue a M.S. in Genomics and Bioinformatics at GWU in Washington D.C., and then a Ph.D. in Computational Biology from Washington University in St. Louis, where he investigated the impact of DNA copy number variation on gene expression in Dr. Timothy Graubert's lab. His postdoctoral work in the lab of Dr. George Daley at Harvard Medical School and Boston Children’s Hospital included the development and experimental validation of computational methods to assess and improve engineered cells, such as those resulting from directed differentiation of pluripotent stem cells.
