Dr. Aaron Tannenbaum’s research focuses on medical decision-making for patients with critical illness. He is interested in the shared decision-making process that occurs between physicians and surrogate-decision makers, more specifically, how they communicate about values and expectations, and how they define beneficial care for patients, i.e. care that is medically feasible and value-concordant, when making substituted judgments. The goal of his research is to enhance the quality of physician-surrogate decision-making at or near the end-of-life so as to improve psychological outcomes for surrogates, to mitigate moral distress and burnout among clinicians, and to limit non-beneficial and potentially unwanted care for patients.

He received his bachelor of arts degree in cellular neuroscience at Colgate University and subsequently spent two years studying gliomagenesis and novel drug-delivery mechanisms for the treatment of glioblastoma multiforme at Columbia University. Aaron attended medical school at Temple University where he worked on enhancing access to medical care for the homeless community of North Philadelphia. He completed his residency and chief residency at the University of Chicago, where he was also a fellow at the MacLean Center for Clinical Medical Ethics. He is currently a Pulmonary and Critical Care Medicine fellow at the University of Pennsylvania as well as a candidate for a Master's degree in Healthy Policy (MSHP) at Penn and an associate fellow at the Leonard Davis Institute of Health Economics.

Aaron lives with his wife in West (best?) Philadelphia where they spend time dreaming of mountains, skiing, Adirondack lakes, culinary experiences, and future outdoor adventures. Music is omnipresent.
