About

• Hi, I graduated from Michigan State University in 2021, where I was working under Matthew Hedden.
• I was a postdoctoral researcher at the Max Planck Institute for Mathematics, Bonn for the 2021-22 academic year.
• In Fall-2022, I was at MSRI, Berkeley, as a Postdoctoral Fellow for the Floer Homotopy Theory program
• From Spring-2023 to Spring 2025, I will be in Rutgers University as a Hill assistant professor, working with Kristen Hendricks
• I will join Dartmouth College from this summer as a tenure-track faculty.
• Here is an article in the Quanta Magazine on a paper that I co-authored.
• Here is my CV.
• In summer 2023, I supervised a DIMACS REU (with Hendricks). Here is an article that my students Jay Patwardhan (Rutgers), Zheheng Xiao (Columbia) wrote.
• I am teaching a graduate topics course at Rutgers titled 'Floer homology and low-dimensional topology' in Spring 2024.
• I am co-organizing a special session at the JMM, 2025, 'Concordance and Cobordism in Low Dimensions' with Maggie Miller and Ryan Stees. Together with other members of the g&t group in Rutgers, I am co-organizing the 'Rutgers Geometry and Topology Seminar'.
• I will be in a AIM-SQuaRE with Irving Dai, Maggie Miller and Matt Stoffregen from 2025.
