Context Sensing and In-Context Interventions for Social Anxiety
Context Sensing and In-Context Interventions for Social Anxiety
working with Profs. Laura E. Barnes and Bethany A. Teachman
We use passively sensed biobehavioral data from wearables to detect state anxiety and social contexts relevant to Social Anxiety Disorder (SAD). The ultimate goal is to develop personalized, context-sensitive just-in-time adaptive interventions (JITAIs) for SAD, enhancing digital mental health care accessibility and effectiveness.
Patient-Provider Communication Assessment and Augmentation
Patient-Provider Communication Assessment and Augmentation
working with Profs. Laura E. Barnes, Virginia T. LeBaron, and Tabor E. Flickinger
We merge mobile health with language models to develop tools for understanding patient-clinician interactions. These tools are designed for use in both clinical and online communication settings. The goal is to enhance healthcare communication and thereby improve the quality of treatment, especially in palliative care.
LLM-empowered Emotion Management Agent for Cancer Survivors
LLM-empowered Emotion Management Agent for Cancer Survivors
working with Profs. Philip Chow, Katharine Daniel, and Laura E. Barnes
We integrate smartphone passive and active sensing signals from cancer survivors to understand their perspectives and contexts. LLM-empowered emotion management agent leverages the contextual factors to deliver adaptive and context-aware support when and where needed.
