Associate Professor, Crop Physiology
Jessica Alba Torrion, Ph.D.
Dr. Torrion joined at Montana State University in 2014 as a field crop physiologist studying abiotic stresses in plants with the goal of increasing productivity and resiliency of crops or specific traits to stress. Prior, she was trained conducting field research and outreach at the University of Nebraska-Lincoln as a postdoctoral researcher of which she studied whole crop physiology of soybean. She completed her Ph.D. degree in 2008 at Texas Tech University on cotton crop water stress analysis. In Montana, she studies cereals, oil crops, pulses, and forages. Dr. Torrion has 65% research appointment, 10% teaching, and 25% administration serving as the research center superintendent of the Northwestern Agricultural Research Center.
