Faculty Research

Professor Winncy Du with pipe-inspecting robot. Developing a reliable way to inspect utility pipes transporting water, fuel, waste, or cables for damage is critical.

Scaled model of parabolic trough used for solar energy concentration, installed in
wind tunnel. A force balance (not shown) is used to measure wind drag forces on the
concentrator and supporting structures.

Rack-and-pinion mechanism in SU-8 polymer by ultrathick photolithography. The rack
moves linearly in guided channels to turn the pinion. The moving parts were released
by dissolving a thinner layer of lift-of-resist underneath the structural SU-8 layer.
Although San Jose State University's primary mission is teaching and education, research in mechanical and aerospace engineering is a vital part of keeping our programs current and engaging. Our research objective is multifold: to engage in applied research with industry and government collaborators; to involve and educate undergraduate and graduate students in the frontiers of mechanical and aerospace engineering; and to satisfy the needs of Silicon Valley businesses and industries in this era of rapid technological advances. Potential research sponsors should contact faculty with the relevant expertise directly, or the department chair.
The areas of research undertaken by our faculty are diverse and ever-changing. For the latest information, please go directly to the websites of individual faculty members.
