• Adib Amini

  Program Director

  Adib Amini, Ph.D., PE, ENV SP, BCEE serves as Program Director in the College of Engineering’s Office of Interdisciplinary Professional Programs, with a focus on Water, Wastewater, Stormwater, and Sustainability. Dr. Amini also works with cities and industries as an engineering consultant, with experience in both drinking water and wastewater treatment. Dr. Amini has expertise in sustainability, engineering design, technology innovation, and renewable energy. Dr. Amini’s work has included the design of novel technologies, including on-site energy systems at facilities. He spearheaded the designs for the first wastewater treatment facilities in Iowa that are 100% powered by on-site renewable energy systems. Dr. Amini invented a novel system for ventilation of rated spaces, such as wastewater headworks buildings, for which he holds a provisional patent. Dr. Amini also has performed award-winning research in technology innovation and sustainability. Dr. Amini has spoken widely at conferences on topics related to water/wastewater treatment, sustainability, PFAS, on-site energy systems, and resilient infrastructure.
