Charlie Tsai

Graduate Student

My research interests mainly involve:

  • Studying non-precious catalysts for electrochemical hydrogen evolution, ammonia synthesis, CO2 reduction as well as thermochemical alcohol synthesis and methane activation.
  • Developing approximate physical models for predicting the energetics and kinetics of catalytic reactions.
  • Using supervised machine learning methods for the high-throughput screening of catalytic materials such as metal alloys

I have also created a web interface for searching and visualizing catalytic data here.
