Bio
I am an algorithm researcher at the Weizmann Institute of Science working on computer vision, remote sensing, and environmental AI. My research focuses on developing deep learning methods for satellite-based atmospheric monitoring, multimodal data fusion, and image understanding. I previously worked on fundamental problems in computer vision, including faint edge detection, multispectral registration, and image fusion, publishing in venues such as TPAMI, CVPR, ICIP, ICPR, and ICASSP.
I am currently working in Rudich's Lab at the Weizmann Institute, specializing in remote sensing. I earned my Ph.D. in Computer Science from Kingston University London (2021) under Professor Jean-Christophe Nebel's supervision.
Prior to that, I completed my M.Sc. in Computer Science at the Weizmann Institute of Science (2013), where I worked with Professor Ronen Basri, following a B.Sc. in Computer Science from the Hebrew University of Jerusalem (2011).
During my time at Applied Materials, I gained valuable industry experience in technology development and implementation, which motivated me to pursue an MBA from The Open University (2024).
