It’s that time of year again: graduate admissions season. Inspired by Phillip Isola’s post today on doing a PhD in the age of AI (highly recommended!), I share some thoughts on how to email a professor about joining their lab. It’s a first cut, one person’s perspective, and meant to be a living document and discussion starter. Add your perspective via Margin Notes!

At one point, MIT thought neural networks weren’t worth teaching in intro #AI. Trends change. Fundamentals don’t.

I’ve launched 2 new course websites for my Introduction to #ComputerVision and #DeepLearning in Computer Vision courses. 🆕 Gaussian Splatting 🆕 Flow Matching 🆕 Sparse Autoencoders 🆕 Lecture Notes (work in progress) The videos don’t include voiceovers, but that’s coming in a future revision 🤞 Share your feedback in the thread.

AI won’t just change how we assess students. It can also transform how we teach them. Interactive visualizations can make abstract concepts more intuitive and engaging. Check out this epipolar geometry visualization created with Codex. Link to interactive webpage in thread.

Back to the lecture prep grind. VERY early version of my lecture on Policy Gradients. With #computervision and #robotics research appearing to converge, at least based on #CVPR2026 and my European tour conversations, it feels like good timing 😉

Visualization of the day: Eigenfaces When I started #computervision research as an undergrad, eigenfaces were the rage. The pioneering work of Sirovich & Kirby and Pentland & Turk was everywhere. So much great related work by Allan Jepson, David Fleet, Michael Black, and multidimensional extensions by M. Alex O. Vasilescu! A fun one to revisit.

My publicity chair retirement didn't last long 😉 I just joined the #ECCV2026 European Conference on Computer Vision #ECCV2026 publicity team 😅 New mask, same task. We are looking to grow our team and coverage, including adding a social media account in China. Stay tuned.
