Todd Ogden, Ph.D. is Associate Professor of Biostatistics (Psychiatry) at Columbia University and Research Scientistin the Division of Molecular Imaging and Neuropathology (M.I.N.D.) at the New York State Psychiatric Institute. Dr. Ogden is Leader of the Conte Center for Suicide Prevention Project 6, Statistical Models of Suicidal Behavior and Brain Biology Using Large Data Sets.
Dr. Ogden has interests in a wide variety of topics in both statistical methodology and various application areas.
He is currently collaborating with researchers at the New York State Psychiatric Institute on various statistical modeling issues with the analysis of data from brain imaging studies relating to suicide risk and other topics.
Additional ongoing interests include functional data analysis, nonparametric regression, wavelet methods, statistical modeling, statistical computing, and statistical education.
