Assistant Professor of Clinical Psychiatry at Columbia University Medical Center
Dr. Horga’s research is focused on the cognitive and neurobiological mechanisms underlying cognition and learning in health and neuropsychiatric illness. More specifically, he is interested in how the brain forms internal models of the external world by learning environmental regularities, and how a disruption in this process may result in aberrant perceptions and beliefs such as those that characterize psychotic symptoms in schizophrenia. To this end, his research uses functional magnetic resonance imaging (fMRI) while participants perform a particular cognitive task or are at rest, molecular and metabolic positron emission tomography (PET) imaging, and computational modeling tools. His research aims at integrating findings from these various imaging modalities with computational models of learning and cognition in order to inform the development of cognitive models of specific psychiatric symptoms, and interrogate their precise neurobiological implementation at the molecular and systems levels, with the ultimate aim to develop novel treatments for these symptoms.
