Travelogue

Regina, 2026

After spending a few weeks in Waterloo, I ventured west to the Summer School on Homotopy Colimits at the University of Regina. We thought about model categories, quasicategories, equivariant things, Goodwillie calculus, and classifying spaces. My conversations with the speakers (and organizers) settled many questions I had on my mind and introduced many more. I also appreciated the chance to reconnect with some attendees of the Atlantic TQFT school.

Glass and plants — Green space in the Education Building (or perhaps the Riddell Centre)

Board with math — Final lecture on functor calculi by Brenda Johnson

Painting — Mural *Before the White Man Came* by John Leman in the Legislative Building

Water and bush — Excursion to Wascana Lake

Trees and path — Some valuable properties of homotopy colimits, per Omar Antolín Camarena

Bushes and lake — Greenery at Wascana Lake, taken on the third evening

Halifax, 2026

Mid-May of 2026 led me to the Atlantic TQFT Spring School at Dalhousie University. I spent the week learning (and chatting) about unitary field theories, \((\infty,n)\)-categories, and quantum invariants. More importantly, I met some incredible people.

Clock tower and sky — Clocktower on the Henry Hicks building

Trees and window — Window in Risley Hall, taken on the first evening

Utrecht, 2025

In the late summer of 2025, I attended the Summer School on Geometry at the Utrecht Geometry Centre, Universiteit Utrecht. I learned a decent amount of differential topology and algebra, among other things.

Fields beside Hans Freudenthalgebouw, taken on the final day of the program

View from window — View from my room in Cambridgelaan

Water in field — Fields, taken on an evening walk in Science Park

College Park, 2025

I spent the summer of 2025 at the University of Maryland via my MathQuantum fellowship. I ended up studying model theory and learning about proposal writing.
