Hi there! If you’re stopping by my site, you’re probably someone who has questions and wants answers. Life is short and the internet is large, so let’s get to it.

What I Do Now 💻 + 🎤

Machine learning scientist at Alexa AI working on the future of conversational artificial intelligence.

What I Did Before 🎓 + 👨‍🔬

Graduate student at Stanford University where I studied computer science and artificial intelligence. I spent 3 wonderful years as a researcher in the Stanford Natural Language Processing Group, where I had the unbelievable fortune to work with Christopher Manning, Percy Liang, Christopher Potts, and other brilliant people.

What Interests Me 🤖

Natural language understanding and anything related to machine learning. I spent years building goal-oriented dialogue agents and have worked on computational semantics and textual inference.
I also believe artificial intelligence will be one of the most transformative paradigm shifts in human history, so thinking about the implications of that keeps me pretty busy 🙂.

Fun Stuff 📲

I am the creator of a mobile app for learning artificial intelligence, machine learning, and deep learning. Check it out on the App Store and Google Play!

Professional Service 👨‍💼
