Bio

Prior to joining Emmanuel College, I was a postdoctoral research fellow in Psychiatry at Harvard Medical School, working at McLean Hospital, Massachusetts General Hospital, and The Broad Institute.  Since joining the faculty at Emmanuel College in 2012, I continue to pursue basic research in psychiatric disease while having the pleasure of introducing students to diverse topics in neuroscience and psychology, as well as to the process of conducting research.

What I Love About Emmanuel:

I love that students at Emmanuel College interact with their professors--they always say hello when you meet in the hallway and readily stop by your office when they want or need to chat. 

Courses I Teach

• PSYC2209 Physiological Bases of Behavior
• PSYC2801 Research Methods and Statistics I
• PSYC2802 Research Methods and Statistics II
• PSYC3205 Neuroendocrinology

Research Focus

My research focuses on animal models of psychiatric disease.  My goal is to examine how genes and the environment interact during critical periods of development to alter an individual's susceptibility to disease.  By looking at changes in both brain and behavior in mouse models, we can better understand the contribution of genetic and environmental factors to psychiatric disease.  Further, by identifying animal models with high validity, we are better able to search for new and more efficacious treatment options that are desperately needed in psychiatry.  Undergraduate students contribute to this research in a number of diverse and important ways--my research would not be possible without them!
