About

I am the James E. Crowfoot Collegiate Professor of Ecology, Natural Resources and Environment. My research focuses on biodiversity and arthropod-mediated ecosystem services in rural and urban agriculture. I also work on spatial ecology of the coffee agroecosystem and am interested more broadly on the links between small-scale sustainable agriculture, biodiversity and food sovereignty. I am co-author of four books, Breakfast of Biodiversity,  Nature’s Matrix: Linking Agriculture, Conservation and Food Sovereignty, and Coffee Agroecology, and Ecological Complexity and Agroecology.

My recent research is related to ecosystem services in agroforestry systems in Mexico and Puerto Rico. In Mexico my lab is investigating how local level multi-species interactions generate autonomous pest control in agroecosystems using coffee agroforests as a model system. We are also interested in critical transitions within the pest systems in coffee. In collaboration with John Vandermeer (University of Michigan) and Stacy Philpott (University of California-Santa Cruz) I established a 45-hectare plot in a shaded organic coffee farm in Chiapas, Mexico, and am conducting research on complex ecological interactions among pests, diseases and natural enemies. In Puerto Rico I collaborate with John Vandermeer and Javier Lugo (University of Puerto Rico, Utuado) in a project that examines tradeoffs and synergies among ecosystem services from coffee farms within the Model Forest of Puerto Rico. This project also investigates how ecosystem services (coffee and food provisioning, conservation of biodiversity, pest control, pollination and carbon storate) respond to local and landscape level factors.  In collaboration with Luis Garcia-Barrios from ECOSUR-San Cristobal (Mexico) I am also developing games to help farmers and students better understand ecological complexity in agroecosystems. After Hurricane Maria, we started a research project examining the resistance and resilience of coffee agroecosystems in the central mountainous region of Puerto Rico. Also, in collaboration with Casa Pueblo, a grassroots community organization, and Boricuá, a network of agroecological farmers in Puerto Rico, we are investigating how gasification, using biomass from farm residues and the trees knocked down by the hurricane, could de use to create a hybrid micro-grid that uses solar energy and syngas. We are also investigating the potential impact of the biochar generated through the gasification process on soil properties, plant growth and crop yield.

Teaching Interests:

I teach “Globalization and its Discontent: Struggles for Food, Water and Energy” (Environ 270), Diverse Farming Systems (NRE 553), and Field Ecology (NRE 556). In my courses I like to challenge students to think for themselves. Most of my courses have a strong Latin American flavor because I am from Latin America (Puerto Rico) and I conduct research in Latin America (Mexico, Mesoamerica and Puerto Rico). Most of my courses are interdisciplinary and are taught from a social justice perspective. I teach undergraduate courses in sustainable development and globalization, and the agroecology and political ecology of food systems, a graduate course in field ecology, a graduate course in diverse farming systems, and graduate seminars on topics that range from conservation in fragmented habitats to food sovereignty.
