About

My name is Pingfan Hu, a PhD candidate in Systems Engineering at George Washington University, advised by Professor John Helveston. My work focuses on data science, quantitative modeling, and software development in sustainable transportation. I build software and analytical models that integrate UI/UX, web frameworks, and databases, with expertise in , Python, and PostgreSQL. I develop websites and web applications using Quarto and Shiny. I am proficient in both hands-on programming and LLM-assisted development using tools such as ChatGPT and Claude.

Projects

My research projects are proudly funded by the Alfred P. Sloan Foundation.

I have 2 focuses in my field of study:

  1. Development of open-source software for survey construction and data analysis. The surveydown package is an open-source, feature-packed platform for programmable and reproducible surveys, combining a Quarto UI, a Shiny web framework, and a PostgreSQL backend. It is designed to address the problems of version control, collaboration, and reproducibility in survey construction. The sdstudio package is a companion of surveydown, providing a GUI for survey building, preview, and easy SQL management.

  2. Researches on human behavior in transportation and sustainability using discrete choice models and data visualization. My smart charging adoption research is implemented with survey-based data analysis that studies BEV (Battery Electric Vehicle) owners’ willingness to opt in smart charging programs. This is followed by the SMC economy analysis. The ultimate goal is to provide insights for policymakers and utilities to design better smart charging programs that benefit both the grid and BEV owners.
