Research Interests ______________________________________________________
My research focuses on using statistical and computational approaches in addressing questions in Population Genomics and Molecular Evolution. My major research interests are:

a) The genetic basis of adaptation. Darwinian positive selection, which reshapes species for the better fit of their offspring, is a very interesting topic that really attracts me. I will be exploring this direction both in terms of long term evolution (Comparative Genomics) and short term standing variations (Population Genetics);

b) Species evolutionary history. The demographic history of a species is not only very important for understanding the history of evolution, but also build a foundation for discerning species adaptation. My research in this direction focuses mainly on human evolutionary history and two domesticated species (i.e. Rice and Dogs).

c) Population Genetics of development and evo-devo. Organismal development is an amazing cellular orchestra starting from a single zygote. This group of cells with diverse functions are first built following large scale construction and deconstruction of many components (morphogenesis). Subsequently, they are actively maintained though homeostasis. There are many interesting population genetic and evolutionary questions in this regard. For example, what is the genealogical relationship of all cells within a multi-cellular organism? What are the roles of stem cells in the genealogy? How this genealogy might differ within and between species?
