Robert Bair, PhD

Senior Development Engineer

Dr. Bair is an expert on anaerobic membrane bioreactors for decentralized wastewater treatment. His passion is seeing technological advancements serving the needs of marginalized communities in developing countries. During his PhD work he worked on the NEWgenerator and has served as designer, builder, and operator of the system. He plans to continue improving the system and wants to see the technology commercialized.

Daniella Saetta, PhD

Post-Doctoral Fellow

Dr. Saetta work at USF & NASA's Kennedy Space Center where she is supporting the Bioregenerative Water Purification project. She received her PhD in Environmental Engineering from Arizona State University in 2021. Her research focused on the implementation of urine diversion systems in the United States. Her research stood on a strong backbone of cyber technologies, including low-cost sensors and data-driven control. Prior to ASU, Daniella received her B.S. and M.E. degrees in Environmental Engineering at the University of Florida.
