  • whatshotResearch Description
    I received my degree in Clinical Psychology from the Pennsylvania State University, and completed my clinical internship at the VA Palo Alto Healthcare System. Prior to joining the faculty at Berkeley, I was a postdoctoral fellow at Stanford University.
    My research group—The Idiographic Dynamics Lab—engages in research at the individual level. We are currently interested in issues of Precision, Personalization, and Prediction in psychopathology and substance use.
    Specifically, we are interested in extending the Precision Medicine paradigm to psychological and psychiatric domains—a Precision Behavioral Health model that complements biomedical approaches by leveraging behavioral data to customize and fine-tune behavioral interventions. We are interested in identifying actionable units of information at the behavioral level of analysis that will allow us to match patients, problems, and optimal interventions.
    Additionally, we believe that the concept of personalization extends beyond treatment delivery and should encompass study design, data collection, and statistical analysis. Recent research in our lab has revealed marked heterogeneity in the temporal patterns, correlational structures, and predictive relationships in psychopathology and substance use.
    Finally, given the heterogeneity in the timing and predictors of individual problems and behaviors, our group is currently working on methods for predicting individual behavior moment to moment, in order to identify when problems might occur. Building accurate prediction systems may allow researchers and clinicians to provide interventions when they are most needed (i.e. "just in time").
    Prospective students interested in joining our lab should have a concentrated interest in idiographic science, personalization, prediction, and related issues.
