  • Professor of Psychiatry and Behavioral Sciences

Research Interests

Molecular, cellular and system mechanisms of abnormal brain development and gene-environment interactions relevant to major schizophrenia and autism more


Mikhail Pletnikov, M.D., Ph.D., is a professor of psychiatry, neuroscience, and molecular and comparative pathobiology at the Johns Hopkins University School of Medicine. His primary research interest is the neurobiology of neurodevelopmental diseases such as schizophrenia and autism. The major focus of his research is on identifying the molecular mechanisms whereby adverse environmental factors interact with one another and/or genetic variants associated to affect brain and behavior development. more

Research & Publications


Dr. Pletnikov’s lab explores these mechanisms in a cell type- and circuit-specific manner, using methods of cell and molecular biology, neuroimmunology, neurochemistry, psychopharmacology and developmental psychobiology. His team also studies the role of non-neuronal cells in mediating adverse effects of drugs of abuse, including opioids, cannabis, and psychedelic compounds.
