Dr. Nazir Ahmad is a crop physiologist and plant breeder specializing in crop stress physiology, nutrient use efficiency, and climate-resilient crop improvement. He earned his Ph.D. from the Chinese Academy of Agricultural Sciences, China, supported by the Chinese Government Scholarship. His doctoral research investigated nitrogen and phosphorus use efficiency and root system architecture in Brassica napus using GWAS, QTL mapping, transcriptomics, and advanced phenotyping. He subsequently conducted postdoctoral research at the University of Missouri on phosphorus use efficiency in soybean and at the University of Tennessee on soybean drought physiology, reproductive resilience, sensor-based phenotyping, and machine learning. His peer-reviewed research includes work on nutrient-use efficiency, root architecture, and soybean flower abortion and recovery under drought. His recognitions include a University of Tennessee Postdoctoral Association Travel Award (2025–2026) and Outstanding Mid-term Exam Assessment (2019–2020). He is a member of the Soil Science Society of America, Crop Science Society of America, and American Society of Plant Biologists.
