| The properties of surfaces and grain
boundaries are influenced by their
geometric and crystallographic structure,
their stoichiometry, and their defect
structure. Professor Rohrer’s research
is aimed at the quantitative study
of interfacial properties with the
goal of defining structure-property
relationships for interfaces. Current
research in the area of polycrystalline
structure has the goals of quantifying
the population of different grain boundary
types, measuring their properties,
understanding the mechanism by which
the network forms during processing,
and understanding the influence that
the network structure has on the macroscopic
properties of the material. Current
research in the area of metal oxide
surfaces has the long range goal of
developing composite polar oxide materials
that make the photolytic production
of hydrogen economically feasible. |
| Gregory S. Rohrer is the W.W. Mullins
Professor of Materials Science and
Engineering, the Head of the Materials
Science and Engineering Department,
and the Director of the NSF sponsored Materials
Research Science and Engineering Center at
Carnegie Mellon University. He received
his bachelor's degree in Physics from
Franklin and Marshall College in 1984
and his Ph.D. in Materials Science
and Engineering from the University
of Pennsylvania in 1989. He is the
author of over 140 publications and
has received the following awards:
the Richard M. Fulrath Award of the
American Ceramic Society, 2004; Fellow
of the American Ceramic Society, 2003;
Ross Coffin Purdy Award of the American
Ceramic Society, 2002; Roland B. Snow
Award of the American Ceramic Society,
1998; National Science Foundation Young
Investigator Award, 1994. Rohrer gave
the Lawley lecture at Drexel University
in 2005 and gave the Winchell Lecture
at Purdue University in 2007. Rohrer
is an Associate Editor of the Journal
of the American Ceramic Society and
was the chair of the Basic Science
Division of the American Ceramic Society
in 2005. |
