Welcome!

I'm a 4th year Ph.D. student at the Department of Earth, Environmental and Planetary Sciences, Brown University, working with Prof. Yongsong Huang. Prior to Brown, I graduated from Peking University with a B.S. in Geology.

Interested in postdoc positions starting 2022.

Research Interests

I'm interested in using biomarkers to reconstruct past climate. I find tools such as DNA sequencing and phylogenetics are especially useful for getting information about the biomarker producers and their growing environments. My previous work has been focused on alkenones (a long chain ketone produced by algae, widely used for paleoceanography reconstructions). My current work includes exploring other biomarkers such as fatty acid, alkanes, GDGTs in Alaska lakes, as well as comparing proxy reconstructions with model and reanalysis data.
