Research Interests

World population continues to grow, but food production has not been growing in pace with the population growth. Because agricultural land has been declining worldwide due to soil erosion, urban development, and salinization, food security is a major challenge that we must face, as we need to produce at least 75% more food by 2050 when the world population reaches 9 billion. Research on how plants grow, develop, and respond to environmental stresses will help us find solutions to make agricultural production sustainable. Abiotic stresses such as drought, salinity, and heat waves cause huge losses in agricultural productivity worldwide. If we improve crops’ tolerance to these stresses, we would be able to produce more food and fiber in arid and semi-arid regions of the world, making food production sustainable. We are using genetic engineering approach to improve cotton, soybean and maize’s tolerance to limited irrigation, elevated temperature, and saline conditions, thereby producing higher yields of these crops in the arid and semiarid regions of the world.
