- PhD Title: Integrated Assessment of Corn Responses to Nitrogen, Irrigation, and Seeding Density Through Productivity, Nitrous Oxide Emissions, and UAV-Based Remote Sensing in Oklahoma
- Year of Completion: 2026
PhD Overview
My research focuses on improving the productivity and environmental sustainability of irrigated corn systems through precision nitrogen and water management. Across two growing seasons in semi-arid Oklahoma, I evaluated how nitrogen rate, irrigation level, and seeding density affected grain yield and its physiological components, nitrogen uptake, nitrogen-use efficiency, and nitrous oxide emissions. I also used UAV imagery and vegetation indices to monitor crop responses and predict yield and nitrogen uptake.
The findings showed that nitrogen management was the main driver of crop productivity and resource-use efficiency. UAV-based monitoring effectively detected crop nitrogen responses, demonstrating its potential to support timely and informed management decisions. My research integrates agronomy, remote sensing, and environmental monitoring to help produce more food with fewer inputs and a smaller environmental footprint.

About Me
I am committed to advancing climate-smart agriculture through research, education, and mentorship. My work combines field experimentation, satellite and UAV-based remote sensing, as well as environmental monitoring to develop practical strategies that improve crop productivity while using water and nitrogen more efficiently.
My goal is to become a faculty leader who translates scientific knowledge into solutions for farmers and communities facing food insecurity, resource limitations, and climate variability. I also aspire to mentor future scientists, particularly women in STEM, and help strengthen agricultural research and education in underserved communities.
