Division of Biostatistics in Psychiatry

Melanie Wall, PhD, Chief


The Division’s activities include developing and applying new methodologies for the design and analysis of psychiatric studies, participating in major, funded research projects, teaching statistics to researchers and fellows of training grants, mentoring graduate students from the Department of Biostatistics at the Mailman School of Public Health at Columbia University, and providing consultations on data-analytic and design issues for grant submission and manuscript preparation. The division hosts numerous seminar series inviting external and internal speakers on topics describing biostatistical methods relevant to psychiatry. The seminars are open and well attended by researchers from all divisions of NYPSI and provide an environment to discuss current biostatistical data analysis problems.


Dr.Melanie Wall, PhD, has been the division’s director since July 2012. The division currently has 5 PhD faculty with the inclusion of Dr. Wall and 5 Masters level biostatisticians: Yuanjia Wang, PhD, Hanga Galfalvy, PhD, Seonjoo Lee, PhD, Adam Ciarleglio, PhD and Jean Choi, MS, Chen Chen, MS, Jennifer Scodes, MS, Tianshu Feng, MS, and finally TseHwei Choo, MPH.


Specific recent methodological work has included developments in the areas of psychometrics, instrument assessment, longitudinal data analysis, causal analysis, generalizability, functional data analysis, modern statistical learning, mapping genetic determinants of complex traits, and implementation science. In synergy with these recent methodological developments and incorporating expertise in clinical trial and observational data analysis, our biostatistics faculty participates in extensive collaborations with many psychiatry researchers including projects studying anxiety disorders, cardiovascular response to emotions, stress markers and birth outcomes of teen pregnancy, substance dependence clinical trials and epidemiology, mental health services research, suicide prevention, eating disorders, and complicated grief.
