Dr. Schuster received his M.D. at Washington University, St. Louis in 1977. He was an intern, resident, and chief resident in Internal Medicine at the University of Washington, Seattle (Robert G. Petersdorf and Philip Fialkow, chairs) and a renal fellow at Southwestern Medical School, Dallas (Harry Jacobson, lab director; Donald W. Seldin, chair). His first faculty position was at the University of Iowa, Iowa City (Francois Abboud, chair). In 1988, he moved to the Albert Einstein College of Medicine in the Bronx (James Scheuer, chair) where he became chief of the Einstein Renal Division in 1992 and chief of the Unified Renal Division (Einstein + Montefiore hospital) in 1998. He was vice-chairman for research from 2000-2002.
Since 2002, he has been Baumritter Professor and University Chairman of the Department of Medicine at Einstein and at Montefiore Medical Center. The Department has ~270 full-time and ~750 voluntary faculty members. It receives ~$40 million annually in NIH dollars, generates clinical practice collections of ~$40 million annually, and manages a hospital budget of ~$25 million annually. The Department administers the fifth largest Internal Medicine house staff training program in the country and accounts for over half of Montefiore's hospital admissions. Since becoming Chairman, Dr. Schuster and his team have significantly exapnded the medical practice, and have simultaneously created the basis for additional investment and growth through attention to the "revenue cycle" (i.e. billings & collections). In part as a result of recruiting new physician-scientists, the Department's grant income increased by 36% between 2002-2005 (the comparable NIH extramural growth rate was 27%). Since 2002, Dr. Schuster and his colleagues in the Department have recruited/appointed six division chiefs; founded the first Einstein Division of General Internal Medicine, which is focused on expanding departmental "dry bench" research; expanded the teaching hospitalist program to an additional campus; and created & launched a performance/RVU-based compensation plan for the clinician-educators. To communicate to a far-flung and complex academic entity, Dr. Schuster writes and sends a weekly email departmental newsletter to over 800 recipients.
Scientifically, Dr. Schuster has focused for 25 years on vasoactive hormones and epithelial transport. His laboratory was the first to show that angiotensin II directly modulates fluid reabsorption by the proximal tubule. For a decade, he worked in acid-base physiology, characterizing the respective transporters of renal collecting duct a and b intercalated cells. In 1995, his laboratory discovered the prostaglandin (PG) transporter "PGT", a finding he has extended to human and mouse genetics, zebrafish, and drug discovery. His laboratory has advanced the hypothesis that PG signaling is akin to neuronal signaling, i.e. the signaling molecule is released and then taken up again by the same cell. Because PGT regulates the expression of, and signaling via, PG receptors, it comprises a new therapeutic target for modulating prostanoid signaling. The NIH has continuously funded his research program since 1983. He is currently the PI on an R01 in its 11th year, funded through 2011, and an NIH OÌBrien Kidney Center, funded through 2008. In recognition of his research accomplishments, he was elected to the American Society for Clinical Investigation (1992) and the Association of American Physicians (1998).
Dr. Schuster is active in clinical medicine and teaching. He serves as the Renal Consult Service attending physician for two months each year; is a frequent discussant of clinical cases with the house staff ("morning report" and "chief of service rounds"); and regularly lectures on renal physiology, pathophysiology, and disease to the Einstein medical students, MD-PhD students, and renal fellows.
