Dr. Diz directs his research activities into two distinct but related areas: water quality and renewable energy.  Over the years, Dr. Diz and his students have extensively studied the water quality of streams along the Pennsylvania Lake Erie shoreline.  In addition to that, a recent area of work has been the utilization of organic waste materials, especially those from agricultural and food processing activities, for the production of renewable energy.  The design of systems to generate renewable fuels has employed both microbial processes, such as anaerobic digestion, as well as thermal conversion, a process known as torrefaction, that can convert most any low-moisture content organic material into fuel pellets similar to but superior to wood pellets.
