Research Interests:

My research interests encompass several critical aspects of turfgrass management and performance. I'm particularly focusing on turfgrass management under environmental stresses, such as shade, cold, heat, and traffic. Additionally, I am interested in exploring how plant growth regulators can be optimized to improve the quality and resilience of golf course and sports turf. I'm also expanding my interest in evaluating cultural and chemical methods of turfgrass weed control.
