I am interested in Ecological Stoichiometry and Limnology. I am in the Environmental Life Sciences (ELS) PhD program in the School of Life Sciences at ASU. Before this, I graduated from Xi’an Jiaotong University with a B.Eng. in Environmental Science and Engineering, and Institute of Hydrobiology (Chinese Academy of Sciences) with a M.S. in Hydrobiology.

Born in a beautiful village near the Jiuzhaigou Valley, a World Natural Heritage site, I developed a deep love for the rivers and lakes there. My best childhood memories in of living with rivers has been driving my research interests. The rivers witnessed my growth, and I witnessed the change of the rivers.

In my research here, I will try to understand the fragile aquatic ecosystems in Qinghai-Tibetan Plateau (Qinghai Lake Watershed and Sanjiangyuan Reserve) using the theory of Ecological Stoichiometry. Qinghai Lake is the largest lake in China, and is facing serious threats, such as lake level decline, grassland degradation, desertification, biodiversity loss, etc. Sanjiangyuan, as the headwaters of the Yellow River, the Yangtze River, and the Lancang River, is especially facing the threats from climate change, permafrost thaw, and grassland degradation. Aquatic ecosystems are strongly influenced by surrounding landscapes and are particularly sensitive to terrestrial changes. My research focuses on the ecological stoichiometry patterns, impacts of watershed characteristics, and terrestrial-aquatic relationship in these areas.
