  • My interests center on achieving patient-centered care through patient-centered health research.

    I am currently conducting a pioneering qualitative study of doctor-patient communication in the hospital, focusing on patients’ dialogues with their physicians. In addition, I have published on the importance of doctor-patient communication to patient satisfaction and on physician professionalism as it interacts with patient choice, and conducted research on how doctors and patients collaboratively set an agenda during the primary care visit.

    I have the privilege of being Core Faculty in the Johns Hopkins Evidence-Based Practice Center (EPC) and the Johns Hopkins Center for Health Sciences and Outcomes Research. I have focused on patient-reported outcomes as a co-investigator on numerous systematic reviews, including those of continuous glucose monitoring and of treatments for Crohn’s disease. In addition, I was lead author of the chapter on patient and family engagement in a recent EPC critical analysis of patient safety practices.

    I maintain an active internal medicine practice in the Johns Hopkins Outpatient Center, and I'm a preceptor in the Adult Medicine housestaff clinic there. I'm involved in applying methods of quality improvement to the outpatient setting.
