Dr. Samuel Essah is the leader of the potato management and whole plant physiology program at the San Luis Valley Research Center, Colorado State University. His research emphasis is on developing management practices for the successful, sustainable, and economic production of potato cultivars, which optimize their genetic potential, while minimizing economic input and environmental degradation.. Samuel is currently a director of the Potato Association of America, Senior Editor of the American Journal of Potato Research, and director of the Association of African Agricultural Professionals in North America.
