Ryan Powell, Ph.D.
Ryan leads Manta’s operations and brings a unique perspective to the development of algal biofuels. Rare among scientists, he has 15+ years of practical experience in large scale agriculture from working on his family’s 2000 acre grain farm. This experience provides practical judgment on what can and cannot be done when producing a low cost commodity (such as oil) on large tracts of land. His focus on pragmatic, cost effective solutions that scale has been the key to Manta’s success in bringing down production costs. This pragmatic problem solving mentality is backed by a deep knowledge of the field of algal biofuels which was the focus of his Ph.D. research. Since founding Manta, he has led his team through the successful completion of more than ten peer-reviewed awards that the company has received. Ryan holds a Ph.D. in algal biofuels from the University of Maryland, and is the inventor of the company’s magnetic algae harvesting technology and low cost continuous flow hydrothermal liquefaction system.
