I apply person-centered mixed methods to investigate techniques for detecting and monitoring brain conditions such as cognitive impairment and mental health. My research philosophy places the people I serve at the center, always integrating their perspective with sound research practices and appropriate technology to develop solutions that best serve their health management needs. I am particularly interested in using digital phenotyping that leverages passive markers of language and behavior to unobtrusively assess and monitor symptoms associated with trauma exposure, cancer-related cognitive impairment, behavioral health, and cognitive decline.

Research supplement award for project titled “Longitudinal Assessment of Post-traumatic Syndromes” investigating smartphone word use by people in the year following a trauma experience. This is the first longitudinal analysis of non-trauma-related language relative to presence and severity of trauma symptoms. Using structural equation modeling, we will model Research Domain Criteria (RDoC) framework constructs and construct trajectories with text message features to determine the value of these features as measures of adverse posttraumatic neuropsychiatric sequelae latent constructs and construct trajectories.
