Dr. Huajin Sheng PhD

I have always been passionate about plant biology and agricultural science. Currently, as a Research Associate, I focus on unraveling the mechanisms of sporopollenin synthesis, transport, and assembly during pollen cell wall formation in plants. With extensive research experience in plant physiology and molecular biology, my work focuses on understanding plant responses to environmental stresses and improving crop traits through advanced biotechnological approaches. My research journey began with investigating the physiological and molecular responses of wheat to heavy metal stress, particularly the role of salicylic acid and sulfur in mitigating Mn toxicity. As a visiting Ph.D. student at Cornell University, I expanded my research to metal homeostasis in monocots, using Brachypodium as a model to study Fe and Cu homeostasis and their interactions with toxic elements like Cd. I applied RNA-Seq, CRISPR/Cas9 genome editing, and synchrotron X-ray fluorescence imaging to explore copper uptake, transport, and its effects on plant fertility. After completing my Ph.D., I moved to Saskatoon and worked as a postdoctoral researcher at the University of Saskatchewan, studying plant signaling pathways that regulate water and nutrient use efficiency. I also contributed to multiple projects, including CRISPR-based gene editing for disease resistance, single-cell transcriptomic analysis of seed development, and breeding programs aimed at improving crop production and nutrient quality. My research integrates molecular biology, plant physiology, and bioinformatics to enhance crop productivity and sustainability. In my free time, I enjoy listening to music and cooking.
