Areas of interest: Molecular systematics of birds and mammals

I am primarily interested in the application of DNA sequence data to phylogeny reconstruction for avian and mammalian groups. Recently, this research has focused on problems of analyzing multigene data sets using parsimony and model-based methods (additive distances and maximum likelihood). My approach has been to characterize the evolutionary dynamics of specific sequence partitions (e.g., codon positions in protein-coding genes, stems and loops in RNA genes, functional domains) by estimating parameter-values for appropriate substitution models, then integrating this information across partitions to obtain an estimated tree. Understanding how the accuracy and precision of this estimate are affected by heterogeneity among partitions is a significant aspect of the research, as is exploration of recent models incorporating among-site rate variation within partitions.
