On fire recently

Blade Runner is a much more visceral movie in the age of AI

Animals and skyline in New Mexico

Dealing with a non Adams spectral sequence…. Guys I’m so scared

I hate AI I hate AI I hate AI

Did you all know that math never ends and is so cool

9AM vs 3PM

I’m a simple man: I hate moving and I love reading Willa Cather

Academic grandpa

This is the most on brand picture of me… pointing at the Adams spectral sequence… I made sure to highlight the acronym…

Had a research visitor for the first time!!! Doing math is so fun :)

New paper alert 🚨

Probably the best thing about being an academic is the days I get to spend at home doing research, blasting fusion-era Miles Davis, hanging out with these goobers

Accepted for publication :)

Finally, peace

You’ve heard of redshift, you’ve heard of blueshift, maybe even whiteshift… but get ready for NOSHIFT

Gonna get this printed on a hat and wear it to conferences. 🧮

Very strange bad feeling inside when I see that famous homotopy theorists are in the Epstein files

Adderall is so stupid. Why am I crying to the Allman brothers at 8am

K theory probably coolest thing of all time

I officially get to do math for at least 3 more years!!!!!

It is a good day and tomorrow I will be a cube!

There’s a past version of myself that would argue to the death that “Room on Fire” was a better album than “Is This It?” and I would now argue to the death with my past self that the opposite is true

UW HOMOTOPY MUG!!!!
