Research Interest
Included in his research history are research in the area of cryogenics (especially in liquid helium) at Los Alamos National Laboratory in New Mexico and the study of statistical mechanics of gas and polymer systems while in the mechanical engineering and chemistry departments at the State University of New York at Stony Brook. This is a representation of a percolation cluster from a simulation program that Dr. Ziff helped develop. This program uses fractals and statistical fractal quantities to simulate and study such processes as flow of fluid through porous rock, gelation, the spread of epidemics, and chemical reactions. Studies using this program were featured in the Jul/Aug 1994 issue of Computers in Physics.
