Biography

Professor Cooley’s research interests are in the vibration and stability of high-speed mechanical systems. His current research involves the design, modeling, and analysis of vibration energy harvesting devices for rotating host systems. Prof. Cooley is also active in gear dynamics and vibration. His current research uses advanced finite element/contact mechanics models to predict the vibration of planetary gears for damage detection. Professor Cooley received a Ph.D. in Mechanical Engineering from Ohio State University in 2012. Prof. Cooley was a research scientist at the University of Michigan-Shanghai Jiao Tong University Joint Institute in Shanghai, China.
