  • Design and develop a smart gas meter
  • Biogas production using residential waste
  • Optimization of the hydrogen production schedule and the strategy of power trading to reduce the production cost of the hydrogen station at CSULA and maximize its environmental benefits


Co-advise the ASCE Environmental Competition Team with Dr. Menezes.
Environmental competition team aims to design a water treatment system that can remove a combination of various contaminants typically found in wastewater.
If you are interested to join the competition team, send me an email, and I would be happy to discuss the possibility.
