My ASLP journal article on asking followup clarification questions just got accepted, and I'll be presenting at ICASSP in the UK next week! In addition, we'll be presenting two abstracts at the Nutrition 2019 conference in June! We're currently recruiting more participants for an expanded pilot study with our Tufts nutritionist collaborators on the spoken food logging system. Contact me if you're interested, or download Coco Nutritionist from the Apple Store to try it out!

I recently accepted a faculty job at Loyola Marymount University, and will be starting in the Fall!!!

About me

I completed my Master of Science degree in June 2015 and will be graduating with my PhD from MIT this June! My primary research interest is natural language processing (NLP), especially spoken language understanding and dialogue systems. For my PhD, I designed novel convolutional neural network models that perform semantic tagging and mapping of natural language meal descriptions to semantically similar USDA food database entries. I also demonstrated that asking followup clarification questions with deep reinforcement learning boosts food recall performance by narrowing down the search space. I showed that these neural convolutional models generalize to other tasks beyond nutrition, including semantic tagging of user queries in flight and movie booking domains, as well as dialogue state tracking for restaurant booking conversations. I am interested in developing conversational agents that use recurrent neural network models to converse naturally with humans, and reinforcement learning to adapt online to users in order to personalize each interaction.
