Dr. Ze Zhu currently holds a researcher position concentrating on advances circular systems of aquaculture, aquaponics, algae and biofloc technology at Purdue University. In 2023, he was awarded his Ph.D. from Wageningen University on nutrient dynamics and bioresource recovery in novel zero-discharge aquaculture systems, including aquaponics and biofloc. He also integrates dynamic modeling, sensors and machine learning to optimize water quality and energy use, and evaluates systems via techno-economic analysis and life cycle assessment.
