I conduct research in forest operations with a focus on timber harvesting efficiency and delivered wood cost. The goal of my research is to generate data that will help forest managers implement their management plans efficiently and allow timber harvesting professionals to harvest and deliver timber to Georgia's forest industry at a competitive cost. Specifically, I am interested in timber harvesting productivity and cost, timber transportation safety and efficiency, timber harvesting on small forest parcels, logging capacity utilization, timber procurement, and the impact of policies/restrictions/
