Making place for conversation and connection.

I build research programs and technical toolkits that improve social collaboration through place-based conversation.

Knowledge · Understanding · Response

My work sits between ethnography, design, and systems engineering, shaped by years of experience in education, conversational AI, and field research.

Research Programs

Local Conversation Studio

Local Conversation Studio is a place-based research and design program dedicated to understanding how locals and visitors negotiate language, identity, and knowledge through everyday conversation. The work combines ethnographic field research and qualitative analysis with the design of small, analog interventions that operate inside live interaction rather than alongside it.

Tools for Conversation

Most conversational AI systems are built on data that flattens real interaction into linear speech, erasing spatial relationships, overlap, and embodied cues. Tools for Conversation investigates how these losses originate not only in models, but in capture, recording, and annotation infrastructure itself. Through a vertically integrated set of tools - from physical instrumentation to human-in-the-loop correction - the program addresses what becomes knowable about conversation based on how it is recorded.
