Currently, he has six ongoing research projects, and has an active program of international research collaboration. He has published ~90 peer-reviewed journal articles, with ~35 in last five years, and over 50 non-refereed publications. He has also delivered ~180 conference presentations, including ~40 invited seminars. His research has made a great impact in the field as indicated by ~1700 citations, an h-index of 21, and a RG of 34.67.

Dr. Wang has taught multiple undergraduate graduate courses, and mentored 11 post-doctoral scientists, eight doctoral students, 18 master students and seven honors students. Students under his mentorship have won many prestigious scholarships and awards. A total of 12 Ph.D. students and post-docs trained in his lab currently hold tenure-track faculty positions or equivalent.

Dr. Wang currently serves as an editor for Forestry: An International Journal of Forestry Research; an Associates Editor for New Forests, Canadian Journal of Forest Research, and Journal of Forestry Research; as a member in the editorial board for Journal of Forest and Environment. He has been frequently consulted by scientific journals, national grant agencies, government agencies and industries. Internally, he have also served many committees at departmental, college and university levels.

 Research Interests

Dr. Wang is specialized in Silviculture and Forest Ecology. He conducts both applied and foundational ecological research in forest ecosystems, mostly in temperate forests. His current research focuses on how natural and anthropogenic disturbances, including fire, weather extreme, pest/disease, biological invasion, and human activities (including management), affect forest ecosystems and their implication to forest resilience and sustainability.
