Education

Research

His research includes the recovery of byproducts from liquid wastes and sludges, fungal treatment of food processing wastewater, and reuse applications of residues from water softening. He has several patents to his name. He has developed processes for creating new products at ethanol plants, purifying alcohol, and keeping exotic species out of coastal waters through disinfestation of ballast water with bromine production through ozonation.

He has focused his attention on making added-value products from crops, including animal feed, food, ethanol and purer potable alcohol. He developed a new animal feed, potentially a new human food source, by developing a process for cultivating fungi on corn processing leftovers being commercialized. His ozonation process disinfestates ships' ballast waters of feral species to avoid introduction into coastal waters by shipping and has been applied on oil tankers.
