Assistant Professor

Dr. Ryan Ziels

Dr. Ryan Ziels joined UBC Civil Engineering as an Assistant Professor in February 2017. His research is in the area of resource recovery via biological waste treatment processes for the benefit of human and environmental health. Specifically, he seeks to advance the knowledge of microbial ecology within these engineered processes, leading to improved performance in the recovery of water, nutrients, bioenergy, and other resources. Currently, Dr. Ziels is investigating anaerobic treatment technologies for the recovery of biomethane, as well as microbial biotechnologies for nutrient removal.

Dr. Ziels received his PhD and MSE degrees in Civil and Environmental Engineering from the University of Washington, and his BS degree in Environmental Resources Engineering from Humboldt State University.
