Dr. McNeal serves as Corn and Soybean Specialist at The University of Tennessee where he has a 100% Extension appointment in the Department of Plant Sciences. Jake received his M.S. (2016) and Ph.D. (2021) from Mississippi State University where he was trained as a systems agronomist in corn, cotton, and soybean production systems. His research focused on sensor-based irrigation management (M.S.) and on evaluating the impact of spray droplet size and carrier volume on the efficacy of pesticide applications in the Mid-South and Southeast (Ph.D.). Through applied research, Jake and his program are working to identify limiting factors to corn and soybean production in Tennessee by taking a systems approach to develop economically sustainable agronomic practices for these cropping systems.

Jackson, TN 38301
Phone: (731) 425-4704
Email: ashekoof@utk.edu

Dr. Shekoofa’s Ph.D. research was focused on kernel development of maize as affected by source/sink ratio. (Her dissertation was written and presented in English.) She was a visiting scientist at Universidad Nacional de Rosario, Argentina from 2009-2010. She conducted postdoc research at North Carolina State University (NCSU) on water stress in turfgrass and crop species. Particular emphasis was given to identifying genetic traits that impart drought tolerance. Dr. Shekoofa’s current research in the Department of Plant Sciences centers on developing an active and nationally recognized program in crop physiology with a focus on plant water saving potential. Her true passion in research lies in discovering more about the action of the environment on plant water movement, leaves stomata conductance, transpiration response, plant resistance, and resilience to environmental changes such as water and/or heat stress.
