NSF Grant for O’Meara and Gilchrist

Congratulations to Brian O’Meara and Mike Gilchrist, who were recently awarded a new grant from NSF for “Population genetics-based codon models.”  They will be developing new methods of phylogenetic reconstruction using protein coding sequences of DNA.  Unlike most work in this area, their methods will be based on evolutionary models that explicitly include the forces of mutation, natural selection and genetic drift.  Their work will result in more accurate inferences of the evolutionary relationships between different taxa and, simultaneously, estimates of the strength of natural selection on the coding sequences.
