Ph.D. University of Pennsylvania (1985): Physical metallurgy and mechanical behavior

Brief Bio:

Easo P. George received his B.Tech. with Distinction in Metallurgical Engineering from the Indian Institute of Technology (Kanpur) in 1981 and Ph.D. in Materials Science and Engineering from the University of Pennsylvania in 1985. After brief stints as Post-Doctoral Fellow at the University of Pennsylvania and Research Engineer at Southwest Research Institute he joined the Oak Ridge National Laboratory in 1987 where he currently heads the Alloying Behavior and Design Group. In 2002 he became a Professor of Materials Science and Engineering at the University of Tennessee as part of the ORNL-UT joint faculty agreement. Among the other positions that he has held are Visiting Scholar at the Ruhr University in Bochum, Germany (2001, 2002) and Visiting Scientist at the National Research Institute for Metals in Tsukuba, Japan (1995, 1997, 1999).

Research Areas:

  • Small-scale mechanical behavior of crystalline and amorphous materials
  • Refractory and precious metals for space power applications
  • Mechanical behavior at extremes of temperature and strain rate
  • Environmental effects on microstructure and mechanical properties
