Research in the Kliman Lab Research Overview Journal Articles with Undergraduates Presentations by Undergraduates Lab Alums
The research in our lab centers on questions in evolution and ecology. We are currently studying (1) the evolutionary effects of variable recombination rate on genetic diversity and codon usage bias, (2) the evolution of codon usage bias in general, and (3) queen conch conservation and demography.

Research Overview    top

The research in our lab involves evolutionary and ecological genetics. The primary research focus is on the causes of variation in synonymous codon usage within and among genes in Drosophila, human papillomaviruses and Cryptococcus. Work on Drosophila (and other Diptera) is in collaboration with Dr. Mohamed Noor at Duke University and Dr. Laurence Loewe at the University of Wisconsin-Madison. Part of our reason for studying codon bias is to better understand the relationship between genetic recombination and (a) genetic diversity and (b) the effectiveness of natural selection. Most of the lab work for these projects (e.g., in-house DNA sequencing and "next-generation" sequencing of whole genomes and transcriptomes) is complete, and our current focus is on the data analysis.

We also carry out research on the demographics and the population/ecological genetics of queen conch, Strombus gigas (right; photo by Judy Malitsch), in Belize, in collaboration with Dr. John Cigliano. The research has combined field work in Belize (e.g., population surveys and tagging), laboratory work (mainly DNA sequencing), and statistical analysis. The genetics component of the research program has been supported by The Conservation International Foundation. The field work has been supported by The Earthwatch Institute. [Photos and information relating to Earthwatch teams are on my Earthwatch page.] We are performing a Before-After-Control-Impact study of the effectiveness of the newly-enforced Sapodilla Cayes Marine Reserve with respect to queen conch abundance and age-structure.
