About

Yale MPH in Health Policy with an applied-math background — focused on AI systems and healthcare AI.

Currently building production voice AI and agentic infrastructure for smart devices and enterprise AI applications.

Long-term threads: agentic AI, human-agent interaction, healthcare AI, voice AI, and AI systems in production.

Selected Work

Five projects that capture the range — from production infrastructure to HCI research.

• AIOS

  AGENTIC INFRASTRUCTURE

  Unified capability layer for agentic AI — multi-model orchestration, agent memory, MCP-native runtime.

• Real-time Voice Agent Runtime

  VOICE AI · HARDWARE

  Production ASR–LLM–TTS pipeline with edge-cloud co-inference. Rust + WebSocket, ~200K wearables in the field.

• HCI-Agent

  HCI RESEARCH

  Multi-agent intervention for academic procrastination — Big Five persona, social norms, and responsibility pressure.

• MedRAG-LLM

  HEALTHCARE AI

  Clinical knowledge–augmented framework. RAG over medical literature for clinical-report analysis.

• LLaVA-Med / Biomedical VLM

  MULTIMODAL

  Vision–language alignment for medical imaging — chest X-ray analysis and radiology reasoning.

Research

Ongoing threads, working papers, and research notes.

• Human-Agent Interaction

  Multi-agent behavioral intervention, procrastination, social influence.

• Healthcare AI

  Clinical reasoning, biomedical NLP, RAG over medical knowledge.

• Multimodal AI

  Biomedical vision-language models, multimodal content analysis.

• Efficient Adaptation
