Research Interests

  • Bio-based fuels and chemicals, food and feed processing, water desalination, air conditioning, high-efficiency engines, jet engines and vertical-lift aircraft. 
  • Developed a wide variety of technologies, including conversion of alcohol fuels from biodegradable wastes and protein sugar recovery from energy cane. In addition, he has developed the StarRotor engine, which is three times more efficient than the conventional internal combustion engine.
  • The MixAlco Process™ – A lignocelluloses route to chemicals and fuels
  • SoluPro™ – Converts waste protein into adhesives and feed additives
  • AdVE™ – An Advanced Vapor-compression and Evaporation technology used for desalinating brackish and salt water into potable water.
