Research
The focus of our lab is to develop statistical methodology for mental health research using data from clinical trials, big administrative databases (e.g., EHRs and health insurance claims), and mHealth devices (e.g., smartphones, wearables). We have developed a statistical framework and produced open-source software to analyze the massive amount of longitudinal data from wearable and smartphone devices collected in research studies from individuals in their natural environments. We are also developing predictive models on various health outcomes. Through our collaborations with the Institute of Geriatric Psychiatry and ALACRITY Research Center, we have designed and analyzed several randomized trials (including randomized cluster trials) that studied various behavioral interventions, psychotherapies, drugs, and home care management interventions on older adults with depression, psychosis, and bipolar disorder. Our team aims to understand the interplay between multiple correlated outcomes in determining treatment efficacy, mediating treatment effect, and discovering patient sub-groups. This information could be beneficial in predicting treatment effects based on baseline characteristics.
Current Projects:
Gamification to Improve Psychotherapy Adherence and Clinical Outcomes in Depressed Older Adults
Adherence to Psychotherapy Prediction using Passive and Active Data
Passive Sensing Activity Levels and Behavioral Activation in Psychotherapies for Late Life Depression
Algorithms for Processing Passively-Sensed mHealth Data
Stress Detection using Passively-Sensed mHealth Data
Bio
Dr. Samprit Banerjee received his BStat and MStat from the Indian Statistical Institute, Kolkata, India. He went on to obtain his PhD in biostatistics from the University of Alabama, Birmingham. He has been working at Weill Cornell Medicine in the Division of Biostatistics since 2008, first in the Department of Public Health, then the Department of Healthcare Policy and Research, and currently the Department of Population Health Sciences. He has experience as a biostatistician in biomedical collaborations, which range from randomized clinical trials, observational cohort studies, comparative effectiveness research, analysis of mHealth data (smartphones and wearables), analysis of big data (EHR, claims, large registries and cohorts), statistical genetics, and cancer genomics.
