My research ranges across the fields of phylogeography, molecular phylogenetics, molecular ecology, organismal diversification, phylogenetic
methodology, animal communication, and
mating systems, all with emphasis on acoustically signaling insects (the
"singing insects"), which make excellent model systems for such work. I have been fortunate to be involved in many field collecting trips for projects on cicada biology and systematics around the world, and my collaborators (through the C. Simon lab) and I have assembled a large collection of DNA- and song-vouchered cicada specimens that will serve as a basis for extensive new work on Cicadidae diversification, taxonomy, and classification.
My technical specialities include bioacoustic analysis
methods, molecular phylogenetic techniques (lab and analytical), field collection, and specimen curation/databasing.
RESEARCH AREAS AND PAPERS
Speciation, phylogeography, song evolution,
and DNA taxonomy in New Zealand cicadas
Key findings include a complete phylogeny for the cicada genus Kikihia and estimation
of the timeframe of diversification. Radiation in Kikihia has been rapid yet
stable in rate throughout the Pliocene and Pleistocene epochs, showing that
diversification rates have not been affected by the major changes in climate cycling through the past five million years.
