The Prof. Hoyt research group studies phase transformations utilizing atomistic simulation techniques such as molecular dynamics and Monte Carlo.


B.S. Cornell, M.S. & Ph.D. UC Berkeley


Professor J.J. Hoyt received his BS degree in Materials Science and Engineering from Cornell University and his MS (1982) and PhD (1986) in Physical Metallurgy from the University of California, Berkeley.  From 1988 to 1996.  Dr. Hoyt was a faculty member in the department of Mechanical and Materials Engineering at Washington State University, achieving the rank of associate professor.  From 1997-2007 Prof. Hoyt was a senior member of the technical staff at the Sandia National Laboratories at both the Livermore, CA and Albuquerque, NM sites.  Prof. joined the department of Materials Science and Engineering at McMaster University in 2007 and in 2012 was named chair of the department.

Prof. Hoyt is the author or co-author of over 100 papers in refereed scientific journals and has presented over 50 invited presentations at national and international scientific conferences.  His research expertise is the study of phase transformations in materials using advanced computational tools such as molecular dynamics and Monte Carlo simulations.
