Teaching

• In Spring 2025 I am teaching Math 354 Section 05: Linear Optimization and Math 541: Introduction to Algebraic Topology II.
• For my past teaching, and other mentoring and service activities, please see here.

Various Organizational Roles at Rutgers

• I am a co-organizer of the Rutgers Geometry/Topology Seminar. If you are on this page, you may also be interested in the Rutgers Symplectic Seminar.
• I am the mathematics department's coordinator for the DIMACS REU. Please be in touch if you have questions not answered by the website at the link.
• I am the faculty adviser for our student AWM chapter and also handle some logistics for the student-led Directed Reading Program.

Research

• I am interested in low dimensional topology, symplectic geometry, and knot theory. Most of my research deals with equivariant versions of Floer-theoretic invariants.
• My research is currently partly supported by an NSF Career Grant DMS-2019396.
