About

I am a Data Scientist & Research Engineer with a PhD in Information Retrieval. Currently building behaviour models and practical ML systems that ship. I have 7+ years of experience across AI/ML, NLP, and OR, with publications in ECIR/SIGIR and patents in CV/chatbots. I am motivated by hard problems and the opportunity to make a real-world impact through technology.
