B. Timothy Himes, PhD, is a research assistant professor in the Department of Neurobiology & Anatomy at Drexel University College of Medicine. He is an instructor in the Gross Anatomy, Microscopic Anatomy and Neuroanatomy threads of the first-year medical school curriculum, and is a facilitator in the Cased Based Learning (CBL) course for first-year medical students. He is also a lecturer in Medical Neuroscience (NEUR 602S).

Research Interests

Recovery of function after spinal cord injury


The goal of Dr. Himes' research has been to understand the mechanisms that contribute to recovery after spinal cord injury and to use this knowledge to develop rational clinical treatments. The emphasis was in the use of adult-derived mesenchymal stem cells as transplants to augment host tissue survival and improve functional recovery following SCI. The effects of adult-derived stem cells in the repair of SCI would be particularly interesting because such cells are readily available and could be generated from the individuals own tissue, avoiding the problem of graft rejection of foreign tissue by the host. Currently Dr. Himes devotes his efforts to teaching.
