Language & conversational systems
Natural language understanding, intent detection, context awareness, and conversational AI for virtual assistants and commerce experiences.
Research
Applied language intelligence
My work spans conversational AI, natural language processing, generative AI, and systems that help people interact with products and services through language.
Generative AI & agents
Generative AI systems, large language models, AI agents, and the evaluation and observability needed to make them useful in practice.
Applied machine learning
Machine learning for language-rich products, including sequence-to-sequence modeling and extracting multiple product entities from dialog.
Intelligent product experiences
Recommendation systems and conversational commerce experiences designed around how people discover, select, and order products.
Selected work & talks
Research in practice
Entity Transformer for multiple product name entities
The work describes a sequence-to-sequence approach for recognizing up to 10 product items in an ordering utterance. The best reported model improved performance by 12% over the non-neural baseline on the reported test set. View the poster.
Multi-facet actions for improved conversational item search refinement
A multi-facet filter manager identifies facets and actions from a user's utterance, applies operations such as exact match, exclusion, greater-than, and less-than filtering, and ranks the remaining catalog items. Show patent.
Talk to APIs through an autonomous agent
Patent application 18/999,673, filed December 23, 2024. The work focuses on an autonomous API agent for interacting with APIs through natural language.
