Interests: Forest and grassland biogeochemistry, conservation biology; coastal plain ponds and grassland restoration on Martha’s Vineyard (MA) and deforestation in Brazil.
Interests: To understand how biogeochemical cycles have dramatically affected, and been dramatically affected by, evolutionary changes in the anatomy and physiology of organisms on Earth, and by the ecological interplay of those organisms above- and below-ground in complex mutualisms, symbioses and food webs.
