Stephen R. Madigosky Ed.D

Professor of Environmental Science and Biology

My work in the area of sustainable development involves creating ventures that promote the preservation of rare and endangered tropical species. My most recent initiative focuses on creating market outlets for Central and South American coffee farmers. This project entices conventional coffee farmers to convert their operations to environmentally friendly shade grown organic conditions by paying them a higher living wage. The "cultivation to cup" program, as it is now called, creates a unique association between university faculty/students, rural coffee farmers, coffee roasters, and food service providers, all for promoting a greener environment. Students get the opportunity to travel each year to Costa Rica to conduct research as a part of this endeavor.

Bruce W. Grant Ph.D

Professor of Biology and Environmental Science

Over the past 24 years, I have directed my scholarly activity to (1) research on urban ecology in southeastern PA (with numerous publications and presentations on urban conservation biology spanning herpetofauna, to stream macroinvertebrates, to urban moth biodiversity, all co-authored with Widener students); (2) research on the pedagogy of academic service learning (locally in Chester, PA, and internationally in Honduras) to enhance my students' higher-level critical thinking and metacognitive skills, civic engagement, and understanding of and engagement in global human sustainability; and (3) research on undergraduate ecological education, which includes three co-authored NSF grants (from which we created "Teaching Issues and Experiments in Ecology" [TIEE], published by the Ecological Society of America and now in its 13th volume), and a publication by the National Academy of Sciences on using evidence-based practitioner research to teach evolution (citation below). To this list, I have recently added a new project bringing together my interests in global biodiversity and international service learning.
