Research Interests

Dr. Kreitzer’s research focuses on the disordered physiological processes associated with Parkinson’s disease. He is an expert in the emerging field of optogenetics—the application of genetic and optical techniques to remotely control brain cells in animals. Using optogenetics, Dr. Kreitzer has identified key neural circuits that are disrupted in Parkinson’s disease. He has also discovered brain circuitry that restores normal behavior in mice modified to model Parkinson’s disease. In addition, he uses sophisticated electrical-recording techniques to probe brain activity at a cellular level. These methods led to seminal discoveries linking changes in motor behavior in Parkinson’s disease with the inability of specific brain cells to be modified.


Dr. Kreitzer serves as a regular reviewer for prominent scientific journals, including Nature, Neuron, Nature Neuroscience and Journal of Neuroscience, and is on the scientific advisory board of Circuit Therapeutics. In 2011, he was honored with the Young Investigator Award from the Society of Neuroscience.


Dr. Kreitzer earned a bachelor’s degree at the University of California, Berkeley, in 1996 and his PhD in neurobiology at Harvard University in 2001. He conducted postdoctoral research in the Nancy Pritzker Laboratory at Stanford University with Dr. Robert Malenka until 2007, when he established his laboratory at Gladstone.
