Dr. Arlin Stoltzfus

Arlin Stoltzfus received his Ph.D. in Biology from the University of Iowa for his laboratory studies of natural variation in the E. coli genome. He then converted to computational biology during a post-doctoral fellowship with W. Ford Doolittle (Dalhousie University, Nova Scotia), where he used computer simulations and statistical data analysis to study the evolution of introns.

Since coming to CARB in 1999, Stoltzfus has maintained a computational research program focused on the evolution of introns, the development of software infrastructure to facilitate comparative (evolutionary) analysis, and the evolutionary role of biases in variation. Software projects include the Bio::NEXUS library, the Nexplorer web server, and the Comparative Data Analysis Ontology. Studies on the role of biases in variation have included evolutionary simulations, population-genetics models, and analysis of comparative and experimental data, including the analysis that resulted in the “EX” measure of experimental exchangeability of amino acids in proteins (Yampolsky and Stoltzfus, 2005).
