Welcome to my site. I am an Associate Professor in the Department of Child and
Adolescent Psychiatry, New York University School of Medicine, and a Research Scientist
at the Nathan S. Kline Institute for Psychiatric Research. I received my PhD in
Biostatistics from Columbia University in 2006. The following sources of support for my
research are gratefully acknowledged: National Institute of Mental Health grant 1 F31
MH73379-01 A1 (Jun. 16, 2005-July 31, 2006); National Science Foundation grant
DMS-0907017 (Aug. 1, 2009-July 31, 2012); National Institute of Biomedical Imaging and
Bioengineering grant 1R01EB009744-01A (PI Ogden) (July 1, 2010-March 1, 2013); National
Institute of Mental Health grant 1R01MH095836-01A1 (Aug. 1, 2012-Apr. 30, 2017). My
department at NYU is also known as the Child Study Center; for further information about
me, please see my page on the Child Study Center website, at

NEWS: I am currently recruiting for a 2- or 3-year NIMH-funded postdoctoral fellowship,
beginning in September 2014. Please contact me for further details.
