Animal movement is an integral part of the fabric of life on Earth, affecting ecological processes in every system. However, mobilities of animals and their associated ecosystem functions are declining at an larming rate. I am interested in all aspects of movement of life, from their patterns and drivers to consequences and conservation. Spanning the Asian highlands and the American West, I am particularly interested in the complex social-ecological landscapes mobile wildlife share with human communities. Using interdisciplinary perspectives and methodologies integrating movement ecology, community ecology, land use science, and social science, I hope to contribute to a more connected world for both humans and nature.

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. Using satellite remote sensing and animal tracking technologies, my research measures the spatio-temporal responses of migratory animals to environmental change, informing actionable and timely conservation solutions.

Ecological interactions in working landscapes
Working lands, such as rangelands, support both biodiversity and human livelihoods and play an essential role alongside protected areas (PAs) to combat today’s biodiversity crisis. Understanding ecological interactions (i.e. competition, herbivory, and parasitism) within working lands is key to addressing potential conflicts between biodiversity and sustainability. My research investigates how land use and management affect ecological interactions in working landscapes.

Data-enabled conservation and sustainability assessment
We have entered an era of unprecedented global commitment and investment in conservation, as marked by the United Nations Convention on Biological Diversity post-2020 biodiversity conservation framework. My work develops data analytics and leverages diverse data types to assess biodiversity and sustainability outcomes that inform policy and management from global to local scales.
