Brief Bio
Dr. Toan is currently teaching junior and senior chemical engineering courses. He has many years of experience in teaching chemical engineering. Previously, he taught chemical, petroleum, and environmental engineering courses at both the University of Wyoming and the University of California – Riverside, including Introduction to Chemical Engineering Computing, Thermodynamics, Reaction Engineering, Engineering Modeling and Analysis, etc.

His research efforts cover diverse projects ranging from biomedicine to energy materials. He has done work in projects funded by NSF and DoE that were published in well-recognized journals such as Nano Energy and Nature Communication. He has also consulted on projects for companies such as Exxon Mobil and Tronox Company. His main research interests are in CO2 capture and conversion, using both computational modeling and new experimental technologies to reduce the energy consumption and capital costs for coal power plants that are building new CO2 capture and conversion units. The intention of this research is to promote both sustainability and profit growth, keeping energy costs for customers low while creating a greener energy solution for the planet.
