Ron Shapira Weber

I recently completed my Ph.D. in Computer Science at the Ben-Gurion University of the Negev, in the Vision, Inference, and Learning (VIL) group, under the supervision of Dr. Oren Freifeld. My research focuses on geometric alignment across time and space: diffeomorphic temporal alignment for time series, fast joint alignment of images, and multi-video synchronization.

Before my Ph.D., I completed an M.Sc. in Cognitive Science at Ben-Gurion University as part of the VIL group, under the supervision of Dr. Oren Freifeld (Computer Science Dept.) and the Computational Psychiatry Lab (Dept. of Brain and Cognitive Science), supervised by Dr. Oren Shriki.

Between 2019–2021 I took a hiatus from academia and worked as an algorithm researcher at BeyondMinds, developing applied machine learning models and systems.
