Dr. Jenkins academic and research focus began with an emphasis on stress related mechanistic functioning and photosynthetic response to global change type of environmental fluctuations. His has now guided most of his research towards achieving maximum productivity for industrial crops in controlled environmental agricultural systems. Dr. Jenkins is now the Vice-Chair of the Horticulture Department at Oaksterdam University and the CEO of Rubisco Research and Consulting. His main research focus is currently on environmental (stomatal) and biochemical (Calvin Cycle) limitations on productivity induced by CO2, light, temperature, H2O, salt stress in the root zone, and nutrients; as well as system design and operations in greenhouses and indoor cultivation facilities.
