Greg has published over 100 journal papers in tribology, and this year is conducting 8 active tribology experiments on the International Space Station. His research interests are in micro- and nano-tribology, life prediction, nanocomposites, sliding electrical contacts, and bio-tribology. Greg received the 1998 ASME Marshall B. Peterson Award and the 2004 ASME Burt L. Newkirk Award for his research contributions to the field of tribology. He was also the conference chairman for the 2008 International Joint Tribology Conference.
