| Research Interests |
Dr. Barmak's research interests include processing, properties,
crystal structure, grain structure,
and texture of polycrystalline metal films for application in integrated
circuits and magnetic recording media; thermodynamics and kinetics
of reactions and phase transformations in nanostructuctured films;
experimental, analytical and simulational studies of transformations
and associated microstructures in thin films; and properties of
grain boundaries. She is a member of the Materials Research Science
and Engineering Center and aims to develop a transmission electron
microscopy based automated orientation imaging technique that can
be applied to the study of nanostructured materials. Characterization
techniques of interest include conventional and micro/nano-calorimetry
(DSC, MEMS nano-DSC), x-ray and electron diffraction (XRD, ED),
and transmission, scanning and orientation imaging microscopy (TEM,
SEM, OIM). Her group has been an internationally recognized group
in the use of differential scanning calorimetry for the study solid
state reactions and phase transformations in thin films. |
| Biography |
Dr. Barmak obtained her B.A. (First Class Hons.) and M.A. degrees
in Natural Sciences, Metallurgy and Materials Science from the
University of Cambridge, England in 1983 and 1987, respectively.
She completed her M.S. in Metallurgy and Ph.D. in Materials Science
at the Massachusetts Institute of Technology in 1985 and 1989,
respectively. During her doctoral work she was a recipient of an
AT&T Foundation Fellowship. Prior to her appointment to the
Faculty at Lehigh in 1992, Dr. Barmak spent three years at IBM
T.J. Watson Research Center and IBM East Fishkill development laboratory
working on materials, structures and processes for advanced generations
of field effect and bipolar junction transistors. She joined the
Department of Materials Science and Engineering at Carnegie Mellon
University in 1999 and was promoted to the rank of Full Professor
in 2002. Dr. Barmak received the National Young Investigator in
1994 and a Deutscheforschunggemeinschaft Fellowship the same year.
She was one of four Technical Chairs of the Materials Research
Society Meeting in Spring 1999. She was been a Visiting Scientist
at the IBM T. J. Watson Research Center 1998-2004. |
