Changwon Suh's research focus with the Computational Science Center is on fostering the applications of materials genomics, specifically materials informatics, dedicated to accelerated discovery and enhancement of materials and devices for advanced solar energy harvesting. He has been involved in the area of materials genomics since 2000. He was engaged in applying materials informatics to a wide range of applications, including design of functional ceramic chemistries for hard materials and high-throughput experimentation of heterogeneous catalysts. In addition to his work in materials informatics, Dr. Suh has experience in transparent conducting oxides, with fundamental research interests in the structure-property relationships of materials. His work includes the use of materials genomics techniques in analyzing experimental data and information from theoretical calculations for photovoltaics applications.

Prior to joining NREL, Dr. Suh was involved in numerous interdisciplinary research projects at Iowa State University that were sponsored by the Office of Naval Research (ONR), the Defense Advanced Research Projects Agency (DARPA), the National Science Foundation (NSF), and the Air Force Office of Scientific Research (AFOSR). He also received a co-author honorable mention in the science and engineering visualization challenge sponsored by Science Magazine and the National Science Foundation (2006). Prior to starting his Ph.D. work at Rensselaer, he worked for 2 years as an associate staff researcher at the Research and Development (R&D) Center of Samsung Corning Co., LTD, Korea. At that time, his work was focused on the development of a tin oxide film coating method for large, curved surfaces and the development of a pilot factory system for the mass production of thin-film-coated products.

He has co-authored four book chapters, 20 articles in scientific journals, an online tutorial (TMS Web site), and 12 symposium proceedings.
