Dr. Sjenneider’s primary area of focus is on the role of the hippocampus with a particular interest in characterizing sex differences and the role of the menstrual cycle on hippocampal-based memory function.

Dr. Sneider has received funding from the National Institute on Drug Abuse to apply magnetic resonance imaging techniques to explore the role of the hippocampus in marijuana dependence, and also has conducted studies in emerging adult binge drinkers and healthy developing teens.

Recently, Dr. Sneider was the recipient of a NARSAD Young Investigator Award (Brain & Behavior Research Foundation) to examine brain chemistry, brain activation, and cognition relative to clinical mood measures in depressed and healthy women.


Dr. CoJuliahen-Gilbert’s work employs cognitive and behavioral measures in conjunction with magnetic resonance imaging and magnetic resonance spectroscopy to investigate the role of brain development in cognitive and emotional regulation during adolescence. She is particularly interested in dynamic prefrontal-limbic interactions that contribute to impulsive or risky behavior in this age group. In the Neurodevelopmental Laboratory on Addictions and Mental Health, she has focused her research on questions regarding the initiation and perpetuation of substance use and abuse during adolescence.

Dr. Cohen-Gilbert is currently conducting a NIAAA-funded study examining neural and cognitive factors predicting adverse outcomes in college drinkers. She is also collaborating with McLean Acute Residential Treatment and Landing Programs to study cognitive-emotional regulation and early treatment outcomes in dually diagnosed adolescents and working with Dr. Marisa Silveri on a longitudinal study of adolescent alcohol use.
