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.

A Latex Template for (Quantitative) Ecology Manuscript

Why LaTeX LaTeX has become increasingly popular for writing academic paper in ecology. I almost exclusively write in LaTeX. My main reasons are LaTeX is so much easier to use than Word for quantitative research.

PhD in numbers

In the near end of my PhD, as a quantitative ecologist, I thought it might be fun to visualize some PhD statistics. Here I am gonna show the record of paper rejections, the diveristy of the journals I published in, and the time series of email exchanges with my advisor.

Summary of my PhD thesis

The Long March for PhD finally came to the end. I am proud of what came out of it. Though all my research projects had quite different motivations originally, they all came together forming a consistent theme: an environment-dependent framework to study how ecological networks maintain or change biodiversity in local ecological communities.
