We are interested in understanding the evolution of social behavior, life history and aging!

Complex Trait Genetics I am interested in the genetic architecture of a variety of behavioral and life history traits in the honey bee. In particular, I pursue a set of covarying behavioral traits known as the "pollen hoarding syndrome". The most recent, NSF-funded research focus is on reproductive variables that may underlie this behavioral syndrome. The research involves  crosses, QTL mapping, pleiotropy tests, and the characterization and functional study of candidate genes.  <Link>

Aging, Behavioral Senescence and Biodemography As part of the NIA program project  "Biodemographic Determinants of Life Span", I investigate social factors that influence the individual life expectancy, explore the mechanisms underlying the extreme phenotypic plasticity in honey bee aging, and study behavioral senescence. <Link>

Intestinal stem cells and phenotypic plasticity of aging in the honey bee In this AFAR-funded project, we try to link cellular proliferation and death (apoptosis) with organismal lifespan. We have identified the midgut as the major organ where these cellular processes may be relevant. <Link>

Using Collaborative Undergraduate Research to Train Students in Mathematics and Biology This NSF-funded initiative aims at inter-disciplinary training in mathematical and biological research with student-centered research groups. <Link>
