I am a PhD candidate at SPRING Lab in EPFL, Switzerland 🇨🇭. I focus on web privacy and security research. I am interested in finding more robust tools to study the opaque web ecosystem! Can we automate security and privacy analysis further?

Clean code proponent and full-stack development enthusiast. Artistically inspired across mediums.
