Dr. Halpern is a critical care physician and tenured professor with advanced training in epidemiology, health services research, and bioethics. His research focuses on improving the effectiveness, efficiency, and equity of health care delivery for patients with or at high risk for serious and critical illnesses. This work is coordinated through the Palliative and Advanced Illness Research (PAIR) Center, which he founded in 2017 and which includes several embedded research programs, including the Acute Care Health Services Research Group, the Fostering Improvement in End-of-Life Decision Science (FIELDS) program, and the Clinical Trials Methods and Outcomes Lab. He also directs the NIA-funded Penn Roybal P30 Center on Palliative Care in Dementia, serves on the Steering Committee of NIA’s IMPACT Collaboratory, and serves on the Advisory Board for Penn’s Center for Health Incentives and Behavioral Economics (CHIBE), having previously been its Deputy Director from 2011-2017. His areas of methodologic expertise include developing and testing behavioral economic interventions, leading longitudinal cohort studies, and improving the design, analysis, and ethics of clinical trials, particularly those using pragmatic designs. The most gratifying part of his career is that he is privileged to mentor many trainees supported by T-, F-, and K-series NIH grants. He is supported by an NHLBI K24 Award to promote his mentorship, and has been honored to receive several awards for outstanding mentorship.
