The Paul Janssen Fellowship is awarded to an outstanding young physician-investigator (M.D. or Ph.D.) to conduct novel translational research in neuroscience related to psychiatric disease and medicine. The Paul Janssen Fellow will be assigned both a basic scientist mentor and a clinical investigator mentor from the faculty at Columbia University to serve as joint mentors. The fellow will take a basic observation made by the basic science mentor and apply it to the study of disease or treatment with the clinical research mentor. The award provides a stipend, commensurate with experience. This one-year fellowship program is potentially renewable for a second year based on performance.
