Yitshak Zohar

Yitshak Zohar received BS and MS degrees in aeronautical engineering from the Technion—Israel Institute of Technology, Haifa, Israel, in 1981 and 1984, respectively, and a PhD degree in aerospace engineering from the University of Southern California (USC), Los Angeles, in 1990. He was a research associate at USC from 1990 to 1992, working on microelectromechanical systems research projects. He was also with the Department of Mechanical Engineering of Hong Kong University of Science and Technology, Hong Kong, as one of the founding faculty members in 1992, where he participated in setting up the Micro Fabrication Center and in establishing the Micromachines Laboratory. Since 2004, he has been a professor in the Department of Aerospace and Mechanical Engineering, The University of Arizona, Tucson, developing a microelectromechanical systems (MEMS)/bio-MEMS program. His research interests include the science and technology of microsystems, in particular, microscale fluid mechanics and heat transfer. Currently, his main research interest is the development of microfluidic systems for bio/chemical/medical applications. Dr. Zohar is a Fellow of the America Society of Mechanical Engineers (ASME). He is an editor of the Journal of Microelectromechanical Systems, and served as the Cochair of the 21st IEEE International Conference on Microelectromechanical Systems, Tucson, AZ, January 13–17, 2008.
