He is now based in Quito Ecuador as the Project Coordinator for E-Tech International. He has taken part in water and sanitation projects in The Philippines, Lesotho, El Salvador, Honduras, and as E-Tech, has been involved in environmental evaluations and community training in Ecuador and Peru. While in Ecuador, he helped train native Shuar communities on environmental baseline monitoring near a proposed open-pit mine and ran workshops to illustrate the impacts of mining on surface water and groundwater. In Peru he worked with the with native Quechua environmental monitors on the Pastaza river to increase their knowledge of contaminated site characterization. He also supported the Kukama community of the Marañon River in a field evaluation of environmental damage caused by oil exploitation in the Pacaya Samiria natural reserve. Ricardo has a bachelor of science in geological engineering from the University of British Columbia where he was part of Engineers Without Borders and the EIESL project, which took a critical look at North-South relations in development projects.

Diana Papoulias - Aquatic Toxicologist

Diana Papoulias is E-Tech’s Aquatic Toxicologist. Dr. Papoulias recently retired after 25 years of conducting research on the adverse effects of chemical and non-chemical stressors on fish and aquatic health for the US Geological Survey’s contaminants and environmental health programs. The applied research conducted by Dr. Papoulias has been used by federal and state natural resource agencies to identify exposure and effects of pollutants at many levels of biological organization from the molecular level to the population level. Much of her work has focused on the large variety of environmental chemicals that affect the endocrine system of fish and amphibians and the adverse effects these chemicals have on reproduction. Diana has worked on projects on remote Pacific atolls contaminated with wartime legacy chemicals, the effects of industrial chemicals along the US-Mexico border, on small stream fishes affected by hydraulic fracturing in Kentucky, and most recently a large oil spill in northern Michigan. She strives to explain the connection between human and wildlife health and the consequences of polluting the planet. Dr. Papoulias has authored or co-authored over 100 peer-reviewed publications and presented her research at many national and international conferences.  Earlier in her career, Diana worked for the Arizona Game and Fish Department as a non-game biologist.  Prior to that she spent four years living in central México working at the orphanage, Nuestros Pequeňos Hermanos, where she built a fish farm to feed the 1,000 resident children; she continues as an advisor on that project today.
