Dr. Sachs received his Ph.D. from the Medical College of Virginia in the Department of Human and Molecular Genetics, where he studied adult and pluripotent stem cell biology specifically related to the regulation of the enzyme telomerase. In his post-doctoral work, he studied the heterotypic interactions of breast cancer cells with adult stem cells in a mouse model. As a scientist for LifeNet Health, Patrick led efforts to generate induced pluripotent stem cells from normal and diseased donor cells and expanded LifeNet鈥檚 tissue engineering capabilities to include cell-centric grafts and therapies. At 桃花社区视频 Dr. Sachs studies the biology of stem cells, regenerative medicine, tissue engineering, cancer biology and neurobiology

Ph.D. in Human and Molecular Genetics, Medical College of Virginia, (2010)

B.S. in Biology, Virginia Commonwealth University, (2002)
