On Feb. 27, Dr. Wang Xueli, a former graduate supervised by Prof. Zhang and Prof. Xi, returned to the research group for a visit. Accompanied by Prof. Zhang, she toured the our lab and took group photos with us. During her doctoral studies, Dr. Wang focused on nitrogen fixation research. After graduation, she moved to France to pursue her postdoctoral studies. We sincerely appreciate Dr. Wang Xueli's visit!
