The theory and methodology of phylogenetic inference from molecular
sequences and morphological data (development of algorithms and
software to facilitate model-based analysis of DNA sequences;
comparison of optimality criteria used to evaluate evolutionary
trees; methods of combining molecular and morphological data using
maximum likelihood; assessing robustness of maximum-likelihood
methods to model violation; exploration and evaluation of
metaheuristics useful in searching for optimal evolutionary trees).
