This fall, the College of Engineering welcomes two new faculty members and one former faculty member. The new members are Dr. Wei Fan of the Chemical Engineering Department and Dr. Frank C. Sup of the Mechanical Engineering Department. We are also happy to welcome back a former longtime member of the Electrical and Computer Engineering Department (ECE), Dr. William J. Leonard, who served variously as a research associate, senior research associate, lecturer, research assistant professor, and research associate professor in the department from 1988 to 2009.
