Professional Interests

I am interested in the basic, translational, and clinical science of neural injury and repair. I have trained with Donald Price and Mahlon Delong in molecular and systems neurosciences and have been part of the group effort in the Hopkins Division of Neuropathology that has made breakthrough discoveries in neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease and Amyotrophic Lateral Sclerosis. In my lab, I have been modeling neural injury for 25 years, both in simple models (axotomy) and in the context of neurodegenerative disease. In the clinic, I have been taking care of the cognitive and neuropsychiatric problems of patients with traumatic brain injury and neurodegenerative diseases for 14 years. Among my research contributions are the characterization of the retrograde responses of peripheral and central neurons to axotomy and also of transsynaptic injury in neocortex and the limbic system. My laboratory has determined the trophic response profiles and developed experimental trophic therapies for injured neurons in the PNS and CNS. I have also used neural stem cells in efforts at reconstituting simple circuits in the injured nervous system, beginning with motor circuits in the spinal cord. In the last three years, I have turned my attention to models of traumatic brain injury, including the development and characterization of a mouse model of blast injury to brain. My main priorities at the present time are the role of traumatic axonal injury in brain circuit disconnection (connectopathies) and in the development of chronic neurodegenerative diseases (tauopathies), as well as therapeutic strategies at preventing or repairing these difficult problems.
