Biographical Information

Professor Steel has spearheaded the development of new mathematical theory that has helped biologists to better recover evolutionary relationships from genetic data. His achievements have included methods for modeling non-homogeneous DNA evolution, the first efficient “supertree” method for allowing biologists to combine trees in different sets of species, and techniques for testing and exploiting different models of evolution. Professor Steel has also applied mathematical techniques to answer unsolved problems and uncover new relationships between different models and approaches in classification, particularly concerning maximum likelihood and statistical consistency. His work has had a major influence in phylogenetic software and methodology and is routinely cited in textbooks and research literature.
