Dr. Tolessa Deksissa is the Director of Water Resources Research Institute (WRRI), College of Agriculture, Urban Sustainability and Environmental Sciences (CAUSES) at the University of the District of Columbia (UDC). Tolessa is a founding and current Technical Director and Quality Assurance officer of Environmental Quality Testing Laboratory (EQTL). He joined UDC in 2006 as a research Associate. Since then, he has been spearheading the national accreditation and recertification of EQTL. His leadership has been instrumental in establishing and expanding environmental and water related research infrastructure and graduate program at UDC. Since 2010, Tolessa is the founding and current Director of Professional Science Master’s Program in Water Resources Management. He has initiated and taught several graduate and undergraduate environmental and sustainability courses, and implemented several research projects funded through USGS, USDA and NSF. His previous and pending research projects include water quality assessment and modeling, emerging contaminants, GIS based modeling of green infrastructure, trace metal analysis in urban soils, fate, and transport of organic contaminants in water, integrated urban wastewater system modeling, adaptive water resources management, integrated urban agriculture and green infrastructure in a circular economy, ecosystem service analysis, and fostering significant learning in sciences. Important parts of his research findings are published in peer reviewed journals, conference proceedings and technical reports. Dr. Deksissa earned his Ph.D. in Environmental Technology and MS in Environmental Sciences, both from Ghent University, Belgium.

Sebhat Tefera is a Project Specialist for the Environmental Quality Testing Laboratory (EQTL), Water Resources Research Institute (WRRI), College of Agriculture, Urban Sustainability and Environmental Sciences (CAUSES) at the University of the District of Columbia. He joined CAUSES in 2013. Prior to joining EQTL, Sebhat was working as an Adjunct Professor at the Community College of the District of Columbia for four years. Prior to the Community College, he worked with the Grocery Manufacturers Association (GMA) formerly known as the National Food Processers Association (NFPA) in Washington, DC for more than 20 years.
