Dr. Donald Webster received his Ph.D. in mechanical engineering from the University of California at Berkeley in 1994. After a postdoctoral research position at Stanford University and a non-tenure track faculty position at the University of Minnesota, he joined the faculty at Georgia Tech in September 1997. Dr. Webster's research expertise lies in environmental fluid mechanics, with an emphasis on the influence of fluid mechanics and turbulence on biological systems. Research objectives have been pursued in two basic ways: 1) studying the fluid mechanics and turbulence characteristics of environmental and biological flows; and 2) developing advanced experimental techniques and facilities necessary to conduct the research. Dr. Websters educational activities related to biological applications include being the co-PI representing the College of Engineering on an Integrative Graduate Education and Research Training program (NSF-supported) to train students in the physics, chemistry, and ecology of chemical and hydrodynamic signaling in aquatic communities. The program includes a series of graduate courses that cut across biology, chemistry and fluid mechanics. As a key part of this program, Dr. Webster has developed a new graduate-level course focused on the fluid mechanics of organisms.

Dr. Webster holds a professional engineering license (PE).
