Manas Geeta Arun

My research interests span quantitative genetics, sex-differences and sexual conflict. My current project (supervised by Jarrod Hadfield and Darren Obbard) combines novel quantitative genetic theory, individual based simulations, bioinformatics and experimental evolution using D. melanogaster to develop a new method of estimating the additive genetic variance for fitness. During my PhD, I used hemiclonal analysis on a laboratory population of D. melanogaster to investigate potential interactions between inter- and intra-locus sexual conflict. Previously I have also used experimental evolution to study the genetic basis (chromosomal basis, dominance patterns, etc.) of immunocompetence in laboratory populations of D. melanogaster.
