Research in my laboratory is focused broadly on the use of phylogenetic
hypotheses for studying patterns of speciation and adaptive radiation
in monophyletic groups of teleost fishes. Much of our primary work
involves the testing and construction of phylogenetic hypotheses
using DNA sequences. Molecular phylogenetic trees are used in studies
of fossil-calibration of molecular clocks, geographic modes of
speciation, the evolution of morphological and ecological disparity,
and estimation of lineage-specific diversification rates.
Current research is focused on several lineages of North American
freshwater fishes, as well as a clade of fishes endemic to the
waters surrounding Antarctica. Investigations are focused on three
systems. (1) Geographic patterns of speciation and tempo of diversification
in the North American endemic daters (Etheostomatinae). (2) Divergence
time estimation using fossil-calibrated molecular clocks and the
evolution of reproductive isolation in the North American endemic
sunfishes and black basses (Centrarchidae). (3) Phylogenetics of
adaptive radiation in Antarctic notothenioid fishes.
