After spending ten years in College administration, most recently as Associate Dean for Research and Graduate Programs, I have returned to my faculty position in the MAE Department where I am resuming my teaching and research interests.

At the graduate level, I have taught introductory and advanced courses in both structural vibrations and acoustic radiation, and I have developed new courses in wave propagation, structural power flow, and statistical energy analysis. I believe in using analytical techniques to emphasize physical understanding of underlying principles so that these principles can be used to guide the design of engineering systems and applications. I am currently developing a new 700-level course that will combine various topics in advanced structural vibrations with the emerging field of statistical energy analysis.

At the undergraduate level, I teach Dynamics of Machines (MAE 315). I connect the course material to traditional engineering applications, giving a lot of examples that illustrate the wide breadth and scope of the subject.

While the subject of structural acoustics is technically challenging, it is also an exciting specialty for a motivated student. It involves fundamental understanding in structural vibration, acoustics, and fluid mechanics along with strength in computational and analytical methods in mathematics. The subject area is also exciting because of its broad applicability to the many engineering problems we face today in transportation, energy, and security. My students, in addition to having strong analytical skills, possess a strong work ethic.

 Outside of work, I enjoy woodworking, hiking and travel.

Research Description

My long-term goal is to teach and conduct research in the areas of vibrations, acoustics and structural dynamics. The specific field of structural acoustics (the coupling of structural vibration and acoustic radiation) is of particular interest to me. My current research focuses on developing structural-acoustic models of undersea structures and acoustic sensors.
