Francis de los Reyes

Professor, University Faculty Scholar

Dr. de los Reyes is a Professor of Civil, Construction, and Environmental Engineering, Associate Faculty of Microbiology, and Training Faculty of Biotechnology at North Carolina State University. In 2013, he was named a University Faculty Scholar. He teaches undergraduate and graduate classes on wastewater treatment plant design, environmental biotechnology and microbiology, fundamentals of environmental engineering, and water and sanitation for developing countries.

He has conducted workshops for wastewater treatment plant operators and professionals in the US and the Philippines. He has also worked in water and sanitation issues in developing countries, and has collaborations in the Philippines, India, China, South Africa, Belgium, and Malawi. He is a TED Fellow (www.ted.com), and his TED talk on sanitation has been viewed over 730,000 times. He received the Gordon Fair Award in Environmental Engineering Education in 2015, the Outstanding Extension Award from NC State, and is a Balik-Scientist awardee of the Philippine Government. He was named Outstanding Alumnus of the University of the Philippines, Outstanding Young Alumnus of Iowa State University, and Outstanding Alumnus of Phil. Science HS. He has received the US National Science Foundation CAREER Award.

His students have won state (NC AWWA/WEA), national (WEF, AAEE) and international (IWA) awards for research presentations and posters. Current and past research projects include: molecular analysis and modeling of the competition between filaments and floc-formers in activated sludge, ecophysiology of nitrifiers and denitrifiers in microbial floc, N removal from swine waste, fate of bioagents in landfills, microbial characterization of landfills, molecular techniques for groundwater remediation sites, foam control methods, factors affecting fats, oils, and grease deposits in sewers, wastewater treatment for rural areas, water reuse systems, novel molecular techniques for detecting denitrifiers, energy from co-digestion, and solving pit latrine emptying problems.

Dr. de los Reyes is on the editorial boards of J. Environ. Eng. and Phil. Science Letters, and has served on the editorial board of Water Research. He has been a consultant for industry, engineering firms, and public utilities on activated sludge operation, solids separation problems, and molecular microbiology techniques.

Research Description

Dr. de los Reyes' research focuses on biological processes and combines modeling, bioreactor experiments, and molecular microbial ecology tools in addressing fundamental and practical issues in environmental biotechnology and environmental engineering. Another research focus is sanitation in developing countries. He is interested in two main areas: the interface between microbial ecology and environmental engineering, and global sanitation. At the ecology-engineering interface, molecular techniques are utilized as powerful tools for the analysis of microbial populations in engineered and natural treatment systems. Environmental process engineering is approached from a fundamental standpoint, combining the insights from molecular (DNA- and RNA-based) approaches with innovative process experiments and modeling. In global water, sanitation, and hygiene (WaSH), improving the technologies along the entire sanitation chain is the main focus. His team has developed a new technology for safely and hygienically emptying pit latrines in Africa and Asia. His recent research includes structure-function studies in wastewater treatment systems, landfills, soils, and decentralized sanitation systems.
