I am a wildlife ecologist. I use spatial and quantitative tools to understand how animals interact with their surround world. More specifically, I focus on ecological responses of wide-ranging animals to environmental changes, particularly landscape fragmentation caused by anthropocentric barriers such as fences, roads, and railways. My study systems are in arid and semi-arid rangelands from the Asian steppe to the American West, where wildlife, humans, and livestock have co-existed for thousands of years. As an ecologist, I am motivated to bridge the nature and human dimensions and to seek a balance between wildlife conservation and human well-being. I value interdisciplinary collaborations, especially with social scientists and artists. Currently, I am working on my Ph.D. dissertation focusing on impacts of fencing on ungulate movement ecology in the Greater Yellowstone Ecosystem.

Animal movement in a changing world
A framework of migratory plasticity in ungulates.
|
Movement is a fundamental way through which individual animals respond to and interact with their external environments. Understanding whether, when, where, and how animals move does not only enrich our knowledge on ecology of the target species, but also shed light on mechanisms of how various ecological processes connect across scales. These information are vital for biodiversity conservation and management in a changing world.

Global impacts of fencing across social and ecological scales
|
Fences might be one of the most prevalent, yet least understood, human infrastructure on earth. Ecologically, fencing can alter animals physiology, movement patterns, habitat use, and ecosystem processes. Often embedded in socio-ecological systems such as rangelands, fences also play a fundamental role in land practices, economic relationships, and social relationships in societies. My research contribute theoretically and empirically to the bourgeoning field of fence ecology.

Draper Natural History Museum lunchtime expedition talk
The Wires that Shape the World: Fence Ecology and Conservation Fencing is one of the most widespread manmade features on Earth, yet they are often omitted from discussions of humanity’s impacts on the environment. Following my journey from the Tibetan plateau to the Greater Yellowstone Ecosystem, I shared the hidden ecological impacts of the wires that have shaped the world. |
Spatial ecology of wildlife in response to human activities
From the Greater Yellowstone Ecosystem to the Yangtze River of China, human activities are gradually encroaching wildlife habitats and altering animal behaviors. Utilizing my technical expertise in GIS and remote sensing, I collaborate with researchers and managers around the world to investigate how wildlife distribution respond to lethal and non-lethal human activities, such as urban development, prescribed burning, sand mining, and agriculture.
