Associate Adjunct Professor
My current researches have two broad focuses. 1, evolution, systematics, and phylogeny of fossil carnivorans (meat-eating mammals) in Cenozoic. In particular, I have concentrated on the fossil history of Canidae (dog family). In collaboration with Blaire Van Valkenburgh and Robert Wayne, we are tackling the issues of the molecular phylogeny and the timing of individual clades, and also their functional implications. 2, Geology and vertebrate paleontology of Tibetan Plateau. This NSF funded, field-oriented program attempts to learn about mammalian evolution in Tibet and their responses to paleoenvironments. The dramatic uplift of the Tibetan Plateau has caused a profound change of the Asian climate and environments. Such a change is recorded in the fossil records of mammals. I am leading a group of American and Chinese geologists and paleontologists to investigate various Cenozoic basins in Tibet and have discovered a number of fossiliferous localities.
