Sheldon Weinbaum


Sheldon Weinbaum: is an American biomedical engineer and biofluid mechanician. He is a CUNY Distinguished Professor Emeritus of Biomedical and Mechanical Engineering at The City College of New York. He is one of nineteen living individuals who is a member of all three U.S. national academies and also the American Academy of Arts and Sciences. He was the founding director of the New York Center for Biomedical Engineering, a regional research consortium involving the BME program at The City College and eight of the premier health care institutions in New York City. He has been a lifelong advocate for women and minorities in science and engineering. He was the lead plaintiff and organizer of a class-action lawsuit charging New York State officials with racially discriminatory funding of its two university systems, CUNY and SUNY, the first CUNY faculty recipient of the Public Service Award of the Fund for the City of New York, and the Inaugural Recipient of the “Diversity Award” of the Biomedical Engineering Society. He is currently chair of the Selection Committee that chooses the annual Sloan Awardees for the outstanding math and science teachers in the New York City public high schools.

Background and personal life

Weinbaum was born and raised in Brooklyn, New York. His parents are Alex Weinbaum, who emigrated to the U.S. from Russia in 1921, and Frances Weinbaum. He attended Jamaica High School, Queens, and Abraham Lincoln High School, Brooklyn, and received his bachelor's degree from Rensselaer Polytechnic Institute in Aeronautical Engineering in 1959. He earned his MS in Applied Physics 1960 and his PhD in Engineering 1963 from Harvard University where he was a Gordon McKay Prize and then National Science Foundation Fellow. His dissertation is entitled “Natural convection phenomena in horizontal circular cylinders” and completed under the direction of George F. Carrier. He subsequently worked for the Avco Everett Research Laboratory and the General Electric Space Sciences Laboratory in Valley Forge, where he did research in high altitude aerodynamics. He developed what is now referred to as the Weinbaum-Weiss model of the high altitude laminar near wake. He became active in the anti-war movement of the 1960s and returned to academia in 1967 as an associate professor in the Department Mechanical Engineering at The City College of New York. He was promoted to professor in 1972, became a Herbert G Kayser Chair Professor in 1980 and a CUNY distinguished professor in 1986. Weinbaum married Alexandra Tamara Wolkowicz in 1962 and they have two children, Alys Eve Weinbaum and Daniel Eden Weinbaum.

Contributions to science and engineering

Weinbaum is widely recognized for novel biomechanical models that have changed existing views in such areas as bone fluid flow and mechanotransduction, vulnerable plaque rupture, the role of the endothelial glycocalyx in initiating intracellular signaling, microvascular fluid exchange, revised Starling hypothesis now referred to as Michel-Weinbaum model for capillary filtration, endothelial transport aspects of arterial disease, glomerular-tubular balance in the renal tubule, and bioheat transfer. In each case he resolved a long-standing “mystery” by discovering either a new structure-such as micro-calcifications in the fibrous caps of vulnerable lesions or leaky junctions for transport of LDL across vascular endothelium- or a new function for a known structure –such as by demonstrating that the glycocalyx on endothelial cells senses the fluid shear stress of the blood flow and transmits it to the intracellular cytoskeleton. He has also proposed a new concept for a high speed train where lift is generated by a giant ski riding on a soft porous material in a channel with impermeable side walls.
Weinbaum has been instrumental in the development of the biomedical engineering program at The City College of New York and CUNY. In 1994 he and Stephen C. Cowin established the New York Center for Biomedical Engineering and in 1999 they introduced the new CUNY PhD program in Biomedical Engineering. This led to the creation of the Department of Biomedical Engineering in 2002 and an undergraduate degree program in this field.

Contributions to diversity

Weinbaum is widely recognized as a pioneering advocate for women and minorities in science and engineering. As an untenured professor he was almost fired in 1969 for his role in supporting Black and Hispanic students in their takeover of the City College campus in their protest against existing admission policies. In 1977 he established the first summer outreach program at The City College for low income public high school students in science and engineering. In 1988 he received the Public Service Award of the Fund for the City of New York from Mayor Edward Koch for his role in recruiting women and minority faculty and students to the Grove School of Engineering.
His 1992 class-action lawsuit Weinbaum vs. Cuomo brought national attention to the alleged racially discriminatory funding of higher education in New York State. The initial positive ruling was overturned on the New York State Court of Appeals in 1996 on the grounds that the state did not have to fund its two university systems CUNY and SUNY equally provided neither university had racially biased admissions. Weinbaum then turned his attention to encouraging high achieving underrepresented minority students to go to graduate school and pursue a PhD in a series of grants from the Sloan Foundation and National Heart, Lung, and Blood Institute at NIH 1997–2013. The success of the latter program is described by Pulitzer Prize winning reporter Kenneth Cooper in “Diverse Issues in Higher Education”.
Under the combined leadership of Weinbaum and John M. Tarbell, Chair of BME from 2004 to 2013, the BME Department has become widely recognized for the diversity of its faculty and graduate students. In the 2011 report of the National Research Council on doctoral programs in the United States the CUNY bioengineering PhD program ranked first nationally in diversity among the 74 ranked programs in the field. As of 3/9/18, 54% of its tenure track faculty and 74% of its PhD students are female and/or URM making it a leader among all STEM programs nationally. Of the 45 PhD students Weinbaum has mentored or co-mentored 17 are female and/or URM. Weinbaum has also played a leadership role in the nomination of women and minority researchers in both the NAE and NAS. He is currently Chair of the Temporary Nominating Group for Class III of the NAS, Engineering and Applied Sciences, and Chair of the Temporary Nominating Committee of NAE to identify such individuals.
