My research interest focus on plant ecology, global change biology, and pollination ecology.

Bee population declines are linked to reduction of nutritional resources due to abiotic and biotic agents. I worked with collaborators to investigate whether global climate change, apicultural practices, land-use intensification and herbivores influence on the nectar quality and quantity in in alpine Tibetan grassland. My research program uses the most nectariferous plant (Saussurea nigrescens) in the eastern Tibetan Plateau to examine these questions in further detail. In alpine Tibetan, nectar production decreased by 90% in asymmetric warming and by 30% in apicultural practices, but nectar yield increased by 17.0 % in low intensity of seed predators and by 80% in moderate grazing intensity.

Currently, I am working on a project trying to testing the effects of soil quality (Change N/P ratios) on the quality and quantity of food resource (Nectar and Pollen), thereby on the bumble bee foraging behavior.
