Research interests

To understand how vegetative ecosystems will shift in response to climate change and human encroachment, it is imperative to reconcile the individual measurable physiological performances of plants with demographic responses. I am passionate about how diverse plant physiological and demographic strategies steer the competitive behavior and invasiveness of distinct plant species and growth forms, leading to species exclusion and/or coexistence in a changing environment. 

Freshly printed

We may have found the world’s largest known liana—a massive climbing plant measuring 866 mm in diameter—in an African forest. Check out our freshly printed global study highlights record-breaking “Champion” lianas from six continents!

New job announcement

I am extremely excited to announce that starting from December 2025, I will transition into the role of Assistant Professor in Global Change Ecology at Virginia Tech. I am looking forward to working alongside my colleagues at the Department of Forest Resources and Environmental Conservation (FREC) and at the Invasive Species Collaborative (ISC) to tackle a wide range of fascinating research questions!

Seminar at New York University

I’m excited to announce that I’ll be giving an invited Seminar at NYU hosted by the Mingzen Lu Lab on November 14th. I’ll be discussing recent work and insights on liana-tree competition and liana proliferation trends in the tropical rainforest. Looking forward to connecting with NYU researchers and students—hope to see you there!
