Steven J. Koester (M’96–SM’02) was born in Defiance, Ohio, in 1966. He received the B.S.E.E. and M.S.E.E. degrees from the University of Notre Dame in 1989 and 1991, respectively. He received his Ph.D. in 1995 from the University of California, Santa Barbara where he performed research on quantum devices in the InAs/AlSb heterostructure system. In 1995, he joined the IBM T. J. Watson Research Center, in Yorktown Heights, New York, as a postdoctoral researcher.  From 1997 to 2006 he was a research staff member at IBM and performed research on a wide variety of SiGe devices including strained Si/SiGe MODFETs, MOSFETs and high-speed photodetectors. From 2006-2010 he served as manager of Exploratory Technology at IBM Research where his team investigated novel devices and 3D integration solutions for post 22-nm-node CMOS technology. Since 2010, he has been a Professor of Electrical and Computer Engineering at the University of Minnesota in Minneapolis, Minnesota where his research focuses on nanostructured electronic and photonic devices. Dr. Koester has authored or co-authored over 150 technical publications and conference presentations, and holds 32 United States patents.
