Nader Vahdati joined the Petroleum Institute (PI) as an Associate Professor and Deputy Chair of the Department of Mechanical Engineering. He received his B.S. (Magna Cum Laude) and M.S. in Mechanical Engineering from the University of Portland, Oregon.  In 1989 he graduated from the University of California, Davis with a Ph.D. in Mechanical Engineering with a specialization in Dynamic Systems and Controls. Prior to joining the PI, he was an associate professor at Nanyang Technological University (NTU), Singapore for 9 years, and prior to NTU, he spent 12 years at Lord Corporation, an aerospace and automotive company, located in Erie Pennsylvania.

His research interests include active, and semi-active vibration and noise control using advance suspension systems, MR and ER-fluid devices, hard disk drive dynamic modeling, energy harvesters and storage technology, new sources of energy, fracture mechanics or metal and rubber components, and biomedical devices. He has supervised 6 completed M.S. theses, 3 completed Ph.D. dissertations. He has published over 45 journal and conference articles. He is member of American Society of Mechanical Engineers (ASME).
