The Paul Janssen Fellowship is awarded to an outstanding young physician-investigator (M.D. or Ph.D. degree) to conduct novel translational research in the field of neuroscience as it relates 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 is a one-year fellowship program, and potentially renewable for a second year based on performance.
