David Lombard, M.D., Ph.D.

Associate Professor of Pathology


Dr. Lombard received a Ph.D. in Biology from Massachusetts Institute of Technology (2000) and an M.D. from Harvard Medical School (2001). He completed residency training in Anatomic Pathology (2001-2003) at Brigham and Women's Hospital in Boston. Following residency training Dr. Lombard joined the laboratory of Professor Frederick Alt at Children's Hospital as a Posdoctoral Fellow. He continued in this role until joining the faculty of the Department of Pathology in September 2008.

Dr. Lombard joined the faculty of the University of Michigan as an Assistant Professor in the Department of Pathology and hold a joint appointment in the Institute of Gerontology as Research Assistant Professor.
