Professional Profiles
🎓 Education
Prof. Dr. Uwe Waller began his academic journey in biology, culminating in the prestigious title of “Dr. rer. nat.” — Doctor of Natural Sciences — in Germany. He earned his Diplom Biologe degree (equivalent to MSc in Biology), specializing in aquatic systems physiology and ecology. His doctoral work focused on the physiological performance and brackish water tolerance of silver carp in Northern Germany. This foundational expertise laid the groundwork for a prolific career in aquatic biology and environmental process engineering. Over time, Waller enriched his academic foundation with interdisciplinary knowledge in engineering, energy systems, and process control, enabling him to lead complex research on sustainable aquaculture. His deep theoretical understanding, combined with hands-on technological applications, allowed him to train students and professionals in both natural and applied sciences, especially in environmental and renewable energy systems.
🧪 Experience
Prof. Dr. Uwe Waller served as a professor at htw saar, where he taught and led programs in biology, aquaculture technology, and renewable energy systems. He was instrumental in developing the university’s environmental engineering bachelor’s program, integrating mathematical, structural, and ecological components. His core teaching spanned general aquaculture, biology of aquaculture species, and microalgae process technology. He also led the Renewable Energy/Energy Systems course, focusing on climate-resilient engineering. Internationally, Waller contributed to Master’s and PhD programs across Germany, Norway, Denmark, and Scotland, and conducted teaching modules in Southeast Asia, including Viet Nam, Thailand, Cambodia, and China. After his retirement in 2021, he continued lecturing abroad and consulting via the Senior Expert Service. Waller’s career merges academia, technology, and global outreach, demonstrating a lifelong commitment to sustainable aquatic and energy systems.
🏅 Awards and Honors
Prof. Dr. Uwe Waller has received numerous accolades throughout his esteemed career. Notably, in 2001, he was awarded the Technologiepreis der Region K.E.R.N., recognizing his innovative contributions to aquaculture technology and renewable energy integration. His work was nationally highlighted in 2012 by the Deutsche Bundesstiftung Umwelt (DBU) as a blueprint for sustainable aquaculture. Beyond formal awards, Waller’s interdisciplinary projects and patents in aquaculture systems and photobioreactors have gained high regard in both academic and industrial circles. His ongoing volunteer work with the Senior Expert Service in Bonn also reflects the recognition and trust placed in his expertise on a global scale. His teaching and scientific cooperation with prestigious universities and research institutions further underscore the respect and admiration he commands in the field of sustainable marine technologies.
🔬 Research Focus
Prof. Dr. Waller’s research centers on sustainable aquaculture systems with a multidisciplinary approach integrating biology, engineering, and environmental science. He developed recirculating aquaculture systems (RAS) for fish and prawns, emphasizing low energy consumption and minimal water usage. His work also explores microalgae cultivation in photobioreactors, contributing to circular systems that recycle nutrients and energy. With an eye on climate change and resource conservation, Waller innovated integrated systems that support secondary recycling processes, benefiting both aquatic organisms and the environment. He further advanced automation and remote control technologies in aquaculture, enhancing system efficiency. His concept development for sustainable ocean aquaculture includes floating marine systems and closed-loop nutrient cycling. Collaborating with international universities and institutions, Waller’s forward-thinking designs aim to meet global food demands while protecting aquatic ecosystems.
