Biography
Education: PhD, University of California, Berkeley (2012) MEM, Duke University (2006) BS, Marywood University (2004) Currently Working on: Projects: Ecological-based sanitation We are collaborating with Sustainable Organic Integrated Livelihoods (SOIL) in Haiti to improve approaches to composting human waste. The composting of human waste and its use as an agricultural soil amendment can tackle three important challenges - providing improved sanitation for vulnerable communities, reducing the spread of intestinal-borne pathogens, and returning nutrients and organic matter to agricultural soils. Our research seeks to quantify these benefits and potential trade-offs.
Research Interest
Extension/Research Interests: My lab studies how nutrients and carbon move into, within, and out of ecosystems. We are particularly interested in applying ecosystem science to research solutions to some of today's most challenging problems, including climate change, sanitation, nutrient pollution, and food production.
