CS + Math @ École Polytechnique

Teaching artifical intelligent models to be intelligent :)

About Me 🚀

I am a passionate about Artificial Intelligence and Machine Learning research. My research interests span computer vision, representation learning, generative models, multimodal learning, and responsible AI. I am driven by the potential of artificial intelligence (AI) to address complex challenges and create impactful solutions. :)

Artificial Intelligence

Outside of work, I love traveling to explore new countries and cultures. I'm also deeply committed to education, and I have volunteered in various countries to support those without access to learning opportunities.
