Therapy - SIGGRAPH 2025 Fast Forward
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…

Committee and course at SGP 2025
I’m serving on the committee for Symposium on Geometry Processing (SGP) taking place in Bilbao in July 2025. I will also present a course on “Deep Learning on Meshes and Point Clouds”.
PhD defended Cum Laude
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).
