1. Data Science: I study human behavior in sustainable transportation using discrete choice models and scenario simulation, focusing on smart charging adoption and economy to generate policy suggestions for policymakers and utilities.
2. Open-Source Software: I develop open-source tools for survey research, including surveydown, a programmable, markdown-based survey platform built on Quarto, Shiny, and PostgreSQL, and its companion GUI sdstudio.
3. Agentic AI Engineering: I build reproducible workflows around Claude Code with plugins, skills, MCPs, and hooks. I document the tutorials and my own workflows in my blog, and run a workshop on GW TAI for researchers and developers.
