Harold May, PI, is a microbiologist and professor at the Marine Biomedicine & Environmental Science Center at the Medical University of South Carolina who has extensive experience in anaerobic microbiology including research in microbial electrochemistry, bioenergy and bioremediation. In the past and present he has researched various aspects biodegradation while collaborating with chemists, molecular biologists and engineers. He has published numerous articles on reductive dehalogeantion, especially in relation to that of polychlorinated biphenyls (PCBs). His most recent research has resulted in publications on electrode reduction by thermophilic bacteria, the in situ detection of PCB dechlorinating bacteria, and the isolation and identification of such microorganisms. He is also investigating the electrofermentation of cellulose and electrosynthesis of fuels from CO₂. Preceding his career at MUSC he worked as a research scientist at Celgene Corp. where he collaborated with engineers on the construction and operation of demonstration scale bioreactors used for the degradation of hazardous compounds. His interaction with engineers has continued through the company he co-founded recently, Microbial Fuel Cell Technologies, LLC, which is presently developing microbial electrochemical systems for fuel production and remediation. His role in the NIEHS funded research focuses on the study of the microorganisms responsible for PCB degradation in sediment, particularly the bioelectrochemical degradation, or electroremediation of PCBs and other persistent organic pollutants.
