I am interested in the role of sexual selection in the formation of
new species. My current project in the Dopman lab explores the
European corn borer male pheromone and the role it plays in
reproductive isolation between the two ECB strains. When I'm not in
the lab, I'm at home with my cats Domo and Baby.
I am interested in processes of speciation, specifically
speciation with gene flow and/or in sympatry. My current
project in the lab is testing for genetic isolation by
reproductive time between populations that differ in
dormancy timing using large genetic data sets (Sequenom
Assays) from different wild populations. I like to use
different computational tools in order to analyze those data
sets, specially using R. When not in the lab, I like to
watch Sci-fi or Fantasy movies or TV shows.
My research focuses on how reproductive isolating barriers
evolve and lead to the formation of new species. I study how
isolation originates between populations within a species as
a result of natural selection, and then compare patterns of
isolation arising within species to those that exist between
species. I am currently working on identifying the genes
that contribute to post-diapause development time between
strains of European corn borers and measuring the fitness
effects of causal genes on temporal isolation in both the
lab and field..
I am interested in speciation and the microevolutionary
processes by which reproductive isolation evolves. My
current project examines whether temporal isolation might
have evolved due to selection along a latitudinal clinal
I study the genetic basis of reproductive isolation and
speciation. I am currently investigating the relationship
between genetic differentiation and reproductive isolation
at known "barrier" genes. My current project focuses on the
pgFAR gene, which is responsible for the different pheromone
blends produced by the two strains of moths.

My current research studies the genetic and physiological
basis of seasonality. Alteration of seasonal timing
contributes to a rapid change of life-history and
speciation, yet little is known the evolution of this trait.
For my research I am using two strains of ECB that differ in
the seasonal timing of generations.
My current research project is related to mapping the
genetic basis of a temporal reproductive barrier. I use
next-generation sequencing technologies and comparative
genomics to develop markers for fine mapping the region
controlling variation in postdiapause development time. This
work offers a rare opportunity to study the evolution of a
potential "speciation gene".
My research is on the relationship between genetic
differentiation and reproductive isolation between sympatric
