My research interests include developing new computer simulation 
algorithms and performing large scale simulations of soft and hard 
condensed matter systems.  We have used "traditional" as well as 
generalized ensemble Monte Carlo methods and have devised the algorithm 
now known in the community as Wang-Landau sampling.  These Monte Carlo 
methods have been used to examine both static and kinetic behavior of a 
variety of models undergoing phase transitions with an emphasis on 
critical and multicritical behavior.  We have also examined models for 
binary alloys, for film growth, for critical wetting, and for soil 
mechanics.  Most recently we have been simulating single chain polymer 
and protein models to elucidate generic behavior as they collapse or 
fold.  Spin dynamics methods have been developed and used to study true 
dynamics in magnetic solids including magnetic nanostructures.

As founding Director of the Center for Simulational Physics at the U. of 
Georgia, I have organized an annual Workshop series that begins its 2nd 
quarter century in 2013.  I have developed and regularly teach three 
courses in computational physics:  An undergraduate course on 
computational physics, a graduate course on Monte Carlo methods, and a 
separate graduate course on molecular dynamics methods.  I am a 
Principal Editor for /Computer Physics Communications/, an Associate 
Editor for the /International Journal of Modern Physics C/, a member of 
the Editorial Board for /Computing in Science and Engineering/ and for 
the /Journal of Statistical Mechanics:  Theory and Experiment/.


My personal research interests: Computational solid state physics using 
density functional techniques, Computational Statistical Physics and
Computational Physics Education Research.


My principal areas of research are statistical physics, polymer physics,
 theory of liquids, phase transitions, critical phenomena, far-from-
 equilibrium systems, and stochastic processes.  I employ a variety of
 theoretical and computational techniques, including cluster approx-
 imations, Monte Carlo simulations, series expansions, and numerical
 analysis of master equations and stochastic partial differential

 I regularly teach Computational Methods, Hydrodynamics, and Physics
 of Climate for undergraduates, and Simulation Methods, Phase
 Transitions, and Statistical Mechanics for our graduate students.
 The latter course always includes two simulation projects.

 I have been an Associate Editor at Physical Review for the last five
