Most of my projects are collaborative with other researchers and inspiring growers. We focus on 1). Biologically improving crop and soil health, and 2) Sustainable use of agricultural by-products. Learn about Biologically-Intensive Agriculture and Organic Farming (BIOAg) for Sustainability here.
Improving Human Health by Reducing Arsenic in Food Legumes
Organic and Alternative Agriculture

Several Western Carolina University students and a faculty member spent a recent bitterly cold weekend in the gray winter woods on campus, working on a project that may provide society with an alternative to traditional burial and cremation.
Cheryl Johnston, director of WCU’s Forensic Osteology Research Station, and the students are collaborating with Katrina Spade, founder and director of the Urban Death Project, in determining the most efficient way of composting humans after death. The goal of Spade’s project is to come up with a more natural way of handling the bodies of the deceased while simultaneously providing rich compost for the Earth.
