My research is at the intersection of AI & healthcare, with a focus on the interface between clinical workflows and predictive models. I utilize methods from the domains of clinical informatics, machine learning, and operations research. My work spans the healthcare AI lifecycle with projects advancing from model development, evaluation, technical integration, and connection with clinical workflows.
