Evolutionary computation is the broad area of computer science that takes its inspiration from natural evolution. Genetic algorithms are search and optimization techniques based on simulated evolution. I am interested in applying mathematical techniques to understand evolutionary computation, including the behavior of genetic algorithms. I have collaborated with Michael Vose and Jon Rowe on dynamical systems and Markov chain models of genetic algorithms. We also have results on the relationship between group actions on the search space and mutation and crossover operators. Estimation-of-distribution algorithms are another class of promising evolutionary-computation based optimization algorithms. I have proposed an estimation-of-distribution algorithm and I am interested in furthering our understanding of these algorithms. I am interested in the relationship between evolutionary computation and biology, and in the use of evolutionary computation to better understand both artificial and natural evolution.
