A one-stop location for information on big-leaf mahogany (Swietenia macrophylla, Meliaceae)


These are the members of our research team. You can see our publications here.

James Grogan, Principal Investigator

James Grogan has studied natural populations of big-leaf mahogany in the Brazilian Amazon since 1995, first as a doctoral candidate at the Yale School of Forestry & Environmental Studies (New Haven, CT, USA), and continuing through Post-doctoral and Research Associate programs. His work complements previous field studies of mahogany in Mexico, Belize, and Bolivia. He currently resides in west Massachusetts, USA.

Christopher Free, Spatial Ecologist

Chris is a graduate of Middlebury College (’10) with a degree in Conservation Biology and a training in GIS science. Chris completed an undergraduate thesis working with Jimmy Grogan and Matt Landis to build a spatially explicit population growth model of big-leaf mahogany. The model has since been adapted into the growth and yield model presented on this website. Chris is now responsible for managing and developing both the spatial and non-spatial versions of the model and for performing the GIS analysis necessary to our research.

Mark Schulze, Director, Andrews Experimental Forest, Blue River, OR, USA

Mark Schulze has studied tropical tree population ecology and forest dynamics in Guatemala and the Brazilian Amazon since 1992. He received his PhD from Pennsylvania State University and postdoctoral training from the University of Florida. He currently lives in and serves as the Director of the H.J. Andrews Experimental Forest in the western Cascades of Oregon. Mark continues field research on high-value timber species and tropical silviculture at several sites in the Brazilian Amazon.

R. Matthew Landis, Consulting Ecologist

Matthew Landis has investigated tree population dynamics and how to model them for nearly 20 years. He received his PhD in Ecology from Dartmouth and was a post-doc at the State University of New York at Stony Brook. Currently he is a Research Scientist with ISciences, LLC (www.isciences.com) in Burlington VT and teaches at Middlebury College in the Department of Biology (website). He has worked on big-leaf mahogany since 2004.

Marco Lentini, Executive Secretary, Instituto Floresta Tropical (IFT), Belém, Pará, Brazil

Marco Lentini is a forester with a Masters in Forest Resource Economics from the University of Florida (Gainesville). Marco coordinates IFT's applied research and training program at the Roberto Bauch Forest Management Center in east Amazonia, in affiliation with the Tropical Forest Foundation’s international network of management and training centers. The Roberto Bauch Forest Management Center has been a leader in the dissemination and improvement of forest management practices in the Amazon since the mid 1990s.

Edson Vidal, Associate Professor, ESALQ / Universidade de São Paulo, Piracicaba, SP, Brazil

Edson Vidal is Doctor Professor on the faculty of Brazil’s leading academic forestry program at ESALQ/University of São Paulo, where he received his PhD in Forest Sciences. Edson has studied forest dynamics in the Brazilian Amazon since 1991. His principal research interests include tropical forest ecology and management, damages and recuperation associated with logging, liana (vine) ecology and management, forest certification, and public policy. He works at field sites throughout the Amazon.
