I am an assistant professor at University of Utrecht’s math department.

My research is in structural graph theory and its algorithmic applications. Lately I’ve been particularly excited about forbidding induced subgraphs, graph coloring and distributed graph algorithms. Broadly, I am interested in discrete math and its applications.

Bio: I obtained my PhD from the Program for Applied and Computational Math at Princeton University in May 2021. Paul Seymour was my advisor. My Phd thesis is On recognition algorithms and structure of graphs with restricted induced cycles. From August 2021- July 2024, I was a postdoc in the Discrete Mathematics Group at the Institute of Basic Sciences in Daejeon, South Korea which is lead by Sang-il Oum. (Sang-il still lets me host my website here. Thanks! 감사합니다!). After that, I was a postdoc in the discrete math group at University of Amsterdam under the supervision of Ross Kang and funded by the NETWORKS consortium from July 2024 – August 2025. Since September 2025, I am an assistant professor at University of Utrecht’s math department in the math modeling group.

Recent and Upcoming:
  • July 20-August 7. I am visiting the Discrete Math Group at IBS in South Korea (Hosted by Sang-il Oum).
