KMap
Understanding how genes and genomes are shaped over many generations by the environment in which organisms live in. We also aim to examine how these changes accumulate and might facilitate the genetic divergence between populations and eventually possibly the origin of species. Lastly we aim to leverage the power of genomics to understand the evolution of insecticide resistance in agricultural pests and to find solution to their management.
