Porter Morgan

I'm a fifth year Math PhD student at the University of Massachussets Amherst, advised by Inanc Baykur. I study low-dimensional topology, specifically 4-manifolds. I'm interested in Lefschetz fibrations, nonorientable 4-manifolds, and exotic smooth structures.

• Belted sum decompositions of fully augmented links. With Brian Ransom, Dean Spyropoulos, Rolland Trapp, and Cameron Ziegler. New York J. Math, 31 (2025):1-42, 2024. [PDF]

Recent and upcoming activity:

• August 2025: Attending the conference on knots, groups, and manifolds at CRM in Montréal, Québec.
• June 2025: Participating in and speaking at Trisectors Workshop 2025 at UT Austin.
• June 2025: Attending the Summer School and Conference on Modern Developments in Low-Dimensional Topology in Trieste, Italy.
• May 2025: Speaking remotely at "Women and Gender Minorities in Symplectic and Contact Geometry and Topology," special session of the AWM Research Symposium in Madison, Wisconsin.

Some other stuff about me:

• I love to cook, and maintain an active food blog. I recently switched from posting on wordpress to posting on lemonhead.ink, a site built from scratch using the Django framework. Any feedback for improving lemonhead.ink is welcome.
• I have a Github page, where you can find some other web development projects. My math research is also up there, but that stuff's top-secret, so those repositories are private.
• Other hobbies include playing billiards and cheering for the Detroit Lions. I used to say that I enjoy road cycling, but that was when I lived in Amherst (where the roads are good). Now that I live in Boston (where the roads are bad), I've switched to running.
