Melanie Wall, PhD, is the director of Mental Health Data Science in the New York State Psychiatric Institute (NYSPI) and Columbia University Department of Psychiatry where she oversees a team of 13 biostatisticians collaborating on predominately NIH funded research projects related to psychiatry. She has worked extensively with modeling complex multilevel and multimodal data on a wide array of psychosocial public health and psychiatric research questions in both clinical studies and large epidemiologic studies (over 300 total journal publications). Her biostatistical expertise includes latent variable modeling (e.g. factor analysis, item response theory, latent class models, structural equation modeling), spatial data modeling (e.g. disease mapping), and longitudinal data analysis including the class of longitudinal models commonly called growth curve mixture models. 

She has collaborated on projects studying the relationships between substance use and HIV risk behaviors as well as models for improving the implementation of evidence based practices for HIV service providers.
