For the SIGGRAPH 2025 Fast Forward, I wanted to do something light, but with high polish. Our paper was about estimating uncertainty for material capture, so I quickly made the association with a therapy session. I cast my colleague (to remain anonymous) as the ‘material’, dressed in a metallic suit and presented live in-costume (imagine standing in a morph suit in front of 2000 people, lots of…

I defended my PhD dissertation titled “Intrinsic approaches to learning and computing on curved surfaces” and received the doctor’s title cum laude 🎉 It was a beautiful day with many happy moments. Thanks to all who made this possible: my collaborators and friends, colleagues and mentors! You can watch a recording of the defense including the Layman’s talk (15 min summary for non-experts).
