J. Andrew Newman, Ph.D.
I'm currently a postdoc at Carnegie Mellon University in the Department of Mathematical Sciences. My research interests currently are in the intersection of topology, combinatorics, and probability, in particular the study of random simplicial complexes and applying the probabilistic method to problems in topology.
I completed my Ph.D. at The Ohio State University in 2018, and prior to my position at CMU, I was a postdoc in the Facets of Complexity research training group working in the Discrete Mathematics and Geometry group at Technische Universität Berlin from 2018 to 2020.
