Zhenqiang (Jack) Ma is a Lynn H. Matthias Professor in Engineering and a Vilas Distinguished Achievement Professor in the Department of Electrical and Computer Engineering at the University of Wisconsin-Madison. He received his B.S. degree in applied physics and B.E. degree in electrical engineering from Tsinghua University in Beijing, China in 1991. He received his M.S. degree in nuclear science and M.S.E. degree in electrical engineering from the University of Michigan-Ann Arbor in 1997, and his Ph.D. degree in electrical engineering from the University of Michigan-Ann Arbor in 2001. Before he joined academia, he worked in semiconductor industry for a year. His present research interests focus on physics, materials, and applications to lattice/crystal structure-mismatched abrupt heterojunctions based on 3D semiconductor materials. He has been actively working on microwave flexible electronics since 2005. In collaboration with biomedical engineering faculty and medical school physicians, he is investigating micro-structured scaffolds for human stem cell-based vision restoration, and special electrodes for neuroprosthesis and neuronmodulation. He has published over 300 journal papers and supervised/advised 60 scientists/postdocs/Ph.Ds. He is a recipient of PECASE and a fellow of AAAS, AIMBE, APS, IEEE, NAI, OPTICA, and SPIE.
