Qiang Sun


Professor Sun conducted postdoctoral research at the University of California-Davis, then joined the Department of Biology at UW-Stevens Point in 2007. Sun’s research interests are in ecological, physiological and pathological xylem anatomy, host plant-pathogen interactions, plant ecophysiology and plant photomorphogenesis. Professor Sun is a manuscript reviewer for more than 12 major scientific journals in the field of plant science.
