Michael Raphael Tadross
Biomedical Engineering
Assistant Professor of Biomedical Engineering
Research Interests
Our goal is to bridge the gap between the study of brain as a computational device and the search for novel neuropathological treatments. We develop technologies to manipulate molecules, cells, and synapses in the brain, and deploy these reagents in mouse models of disease.
Bio
Dr. Tadross' lab develops technologies to rapidly deliver drugs to genetically defined subsets of cells in the brain. By using these reagents in mouse models of neuropsychiatric disease, his group is mapping how specific receptors on defined cells and synapses in the brain give rise to diverse neural computations and behaviors. The approach leverages drugs currently in use to treat human neuropsychiatric disease, facilitating clinically relevant interpretation of the mapping effort.
He received his B.S. degree in Electrical & Computer Engineering at Rutgers University, an M.D.-Ph.D. degree in Biomedical Engineering at the Johns Hopkins School of Medicine, and completed his postdoctoral study in Cellular Neuroscience at Stanford University. He began his independent research program as a fellow at the HHMI Janelia Research Campus.
