Hi y’all!!! I’m Isaiah!

I am a 4th year PhD student in the Department of Mathematics at the University of Pennsylvania (UPenn).

I was awarded the UPenn Math Department’s Good Teaching Award in Spring and Fall 2025!

I am co-advised by Andre Scedrov (UPenn) and Jean-Simon Pacaud Lemay (Macquarie University).

In my 2nd year at UPenn, I did a master’s thesis under Henry Towsner (UPenn) and Andre Scedrov (UPenn).

• Master’s Thesis: Synthetic Differentiation and its Connection to Iteration in Asynchronous Processes (PDF)

Before UPenn, I was an undergrad in math and physics at the University of Maryland (UMD), where I was awarded the Milton Abramowitz Award!

Research Interests

I am super excited about applied category theory, logic, and mathematical physics! In particular, I study

• Differential Categories
• Turing Categories
• Linear Logic
• Categorical Quantum Mechanics
• Markov Categories
• Supersymmetry
