Associate Professor Shunan Zhang of Nanjing Agricultural University is an accomplished plant scientist whose work centers on nitrogen use and its biological functions in major crops. With a strong academic background spanning a Bachelor’s degree, PhD, postdoctoral training, and international research experience as a Visiting Researcher at the Hebrew University of Jerusalem, he has built a robust foundation in crop physiology and molecular biology. His research primarily investigates the genetic and molecular mechanisms by which nitrogen regulates crop growth periods, flowering time, and nitrogen use efficiency (NUE), while also exploring how plant–microbe interactions in the rhizosphere contribute to nitrogen uptake and utilization. He has authored 11 documents, accumulated 397 citations, and holds an h-index of 9, reflecting the growing impact and recognition of his scientific contributions. His publications in leading journals including Advanced Science, Plant Physiology, Plant Biotechnology Journal, Plant and Soil, Journal of Experimental Botany, Crop Journal, and Current Biology have advanced understanding of transcriptional networks, nitrogen signaling pathways, and nutrient–developmental crosstalk in rice. Through his discoveries on key transcription factors, nitrogen-responsive genes, and mechanisms linking carbon–nitrogen balance, Dr. Zhang aims to provide a strong theoretical framework for breeding high-yield, resource-efficient crop varieties. His work not only deepens the fundamental knowledge of plant nutrient regulation but also supports global agricultural sustainability by targeting improved nitrogen use, reduced fertilizer dependency, and enhanced crop performance under varying environmental conditions.
