I am a PhD student specialized in the taxonomy, evolution, and ecology of grasses, especially the economically and ecologically important tribe Andropogoneae.

During my PhD, I will focus on understanding the evolution and ecology of savanna-dominating genera Heteropogon and Themeda using various integrative techniques such as phylogenomics, functional traits, trait evolution and climatic niche analyses.

I also, in the long term, plan to study evolution and ecology of Andropogoneae grasses in Southeast Asian savannas, using molecular, comparative phylogenetic methods, functional traits, online databases, and plot data.
