I use mathematics, statistics, and computation to understand populations of single or multiple types of individuals. Quantitative techniques include products of random matrices, non-negative decompositions of nonnegative matrices, random graphs (directed and undirected), eigenvalue inequalities, and various stochastic processes. Recently I have been working on Taylor's power law of fluctuation scaling. My biological interests include human populations (fertility, mortality, and migration), infectious diseases, food webs, and animal behavior—and variability in all of these areas.
