Hong Koo Kim received his B.S. in Electronic Engineering from the Seoul National University and his M.S. from the Korea Advanced Institute of Science and Technology. He the moved to Pittsburgh where he obtained his Ph.D. in Electrical and Computer Engineering from Carnegie Mellon University. He has received several awards, including the Pitt Innovator Award in 2005, 2006, 2009, and 2012, and also holds numerous patents on nanotechnology. He has been serving as the founding Co-Director of the Petersen Institute of NanoScience and Engineering at the University of Pittsburgh since 2002.
The research activities of my group deal with structural and electronic properties of semiconductor materials and devices. A major tool used in the studies is the scanning tunneling microscope, which allows one to image the atomic structure of a surface and to perform spectroscopic measurements of the electronic energy levels.
Sean Garrett-Roe received his B.A. in Chemistry from Princeton University and his Ph.D. in Physical Chemistry from the University of California Berkeley. He then moved to Switzerland for five years as a postdoctoral fellow at the University of Zurich, where he developed multidimensional vibrational spectroscopy to understand the hydrogen bonding network of liquid water. Sean then joined the University of Pittsburgh in 2011 as an associate professor of Chemistry. His work has won him several prizes in the United States and in Switzerland both for his contribution as a researcher and as an academic teacher.
