Ken Berglund, PhD, is Assistant Professor of Neurosurgery at Emory University School of Medicine. His primary research focus is optogenetic and chemogenetic tool development for neuroscience research. Since he joined Emory University in 2014, he and his colleagues have applied molecular neuromodulation he developed as experimental treatments for various neurological disease conditions in rodents, including epilepsy, stroke, Parkinson’s disease, Alzheimer’s disease, and peripheral nerve injury. His expertise also includes genetic functional and cellular imaging in mouse models. He has developed genetically encoded indicators for calcium and chloride, which revealed various physiological and pathological activity at cellular and subcellular levels in the mouse brain.
