I build AI that makes people's workdays easier and their personal lives more creative.

Currently, I drive agent post-training efforts for Microsoft Copilot: post-training OpenAI models to synergize better with Microsoft's tools, applications, and ecosystem, with a focus on enterprise and workplace scenarios.

Previously, I drove innovation at Samsung Research, prototyping advanced AI features for the next generation of smartphones, spanning everything from core productivity to digital entertainment.

I completed my PhD at KU Leuven in Belgium under Prof. Matthew Blaschko, contributing to many domains in AI, including image generation models, large language models, distributed learning and privacy-preserving machine learning. Before that, I earned my Master's degree from the Karlsruhe Institute of Technology in Germany, using AI to solve control and perception tasks of autonomous driving.

What I work on

Enterprise users ask, and the agent answers by grounding on workplace context (people, content, goals) and acting across Microsoft’s tools and apps. Post-training, guided by user feedback, is my focus.
