Biography

I am a theoretical and computational ecologist. My research program aims to forecast the dynamics of ecological systems under unforeseen environmental conditions, and under incomplete information about the entire system. To this end, my work centers on developing rigorous theory through interdisciplinary tools, devising monitoring-applicable metrics, and validating these approaches with empirical data from a broad range of ecosystems.

I am currently a postdoc with Jonathan Levine at Princeton University. I was a postdoc co-supervised by Andrew Gonzalez at McGill University and Marie-Josée Fortin at University of Toronto from 2020-2022. I received a PhD in Civil and Environmental Engineering from MIT under the supervision of Serguei Saavedra, and a BS in Mathematics from Zhejiang University under the supervision of Yang-Yu Liu.
