Species: Dr. Ezeji’s research program is in the area of fermentation biology focusing on research and outreach in microbial conversion of animal and food industry wastes to bio-energy and other value-added products. Research emphasis is on metabolomics and processes regulating the conversion of agricultural byproducts, co-products or wastes into biofuel and value-added products. In collaboration with other Faculty members, his overall goal is to develop a strong research and outreach program addressing emerging issues faced by Ohio’s expanding bioenergy sector. |
