UI Engineering Caterpillar Lecture On Blood Flow Scheduled Oct. 20

Dr. John M. Tarbell, CUNY and Wallace Coulter Distinguished Professor and chairman of the Department of Biomedical Engineering at The City College of New York, will deliver a Caterpillar Colloquium Series Lecture at 12:30 p.m. Thursday, Oct. 20 in Room 2217 of the Seamans Center for the Engineering Arts and Sciences at the University of Iowa.

The lecture, titled "Mechanical Forces Meet the Arterial Wall: Small Flows Have Large Effects" and hosted by the UI College of Engineering Department of Biomedical Engineering, is free and open to the public.

Tarbell will discuss how mechanical forces driven by blood flow and pressure affect the vascular wall and its constituent cells in profound ways. His lecture will attempt to deconstruct some of the mysteries associated with various blood flows by reviewing critical in vitro, in vivo and computational studies and explaining that small flows induce surprisingly high fluid shear stresses on vascular cells that, in turn, modulate cellular biological responses.

Tarbell earlier this year received the prestigious H.R. Lissner Medal from the American Society of Mechanical Engineers (ASME) for his pioneering research in heart valve fluid mechanics, vascular fluid mechanics, development of the artificial heart and studies of endothelial permeability. A Fellow of the American Institute of Medical and Biological Engineering, the Biomedical Engineering Society and ASME, he joined the City College Department of Biomedical Engineering in 2003 after having previously taught at Penn State University. A graduate of Rutgers University in 1969 with a bachelor's degree in chemical engineering, he received his master's and doctoral degrees in the same field from the University of Delaware in 1972 and 1974, respectively.

The Caterpillar Colloquium Series is made possible by grants awarded to the UI College of Engineering through the UI Foundation by the Caterpillar Foundation of Peoria, Ill. The grants comprise the Caterpillar Excellence Fund, which aids student, faculty and curriculum development in the College of Engineering.

Individuals with disabilities are encouraged to attend all UI-sponsored events. People requiring an accommodation in order to participate in this program are asked to contact in advance the UI College of Engineering Department of Biomedical Engineering at 319-335-5632.
