My primary interests are silviculture and forest ecology; research topics include stand dynamics in managed and unmanaged forests; ecology of natural regeneration; comparative stand development and productivity of pure and mixed stands.
- Natural regeneration of understory vegetation in Southern New England forests, involving issues of silvicultural methods, deer browsing, and competition from hay-scented ferns.
- Long-term ecological monitoring of the system of Forest Reserves that have been recently established in Massachusetts.
- Regeneration of mahogany and associated species in the Yucatan region of Mexico: seed production and dispersal, and seedling survival and growth.
- NRC 100 Environment and Society
- NRC 526 Silviculture
- ECO 604 Forest Stand Dynamics
