About David

David J. Barsky serves as Associate Professor Emeritus in the Department of Mathematics at California State University, San Marcos (CSUSM), a position reflecting his long-standing contributions since joining the faculty in 1995. He earned a Bachelor of Science degree from the University of Delaware and a Doctor of Philosophy from Rutgers University. Barsky's academic research centers on percolation theory within probability and statistical mechanics. His seminal works include 'Sharpness of the Phase Transition in Percolation Models' co-authored with Michael Aizenman, published in Communications in Mathematical Physics in 1987; 'Percolation in Half-Spaces: Equality of Critical Densities and Continuity of the Percolation Probability' with Geoffrey R. Grimmett in Probability Theory and Related Fields in 1991; and 'Critical Exponents for the Contact Process under the Triangle Condition' in the Journal of Statistical Physics in 2003. These publications have significantly influenced percolation theory, earning citations in authoritative texts such as Geoffrey Grimmett's Percolation and demonstrating his impact on the field.
