• Jim McQuarrie

  
  Jim McQuarrie’s professional career is evenly split between engineering consulting and public utility roles. His career in wastewater began as an entry level operator working at a small wastewater treatment plant. As an operator, the exposure to wastewater treatment and the service it brings to society fueled his passion to learn more. After graduate school he moved to engineering consulting and specialized in wastewater process design and in particular application of biofilm processes to achieve intensification of processes to reduce footprint. He returned to the public sector for 10 years serving multiple roles at Metro Water Recovery in Denver Colorado where he was tasked with helping to develop and support a culture of innovation and formalizing establishment of a successful Technology and Innovation Department. Today, Jim serves as the National Wastewater Market Sector Lead at AECOM and now calls Philadelphia, Pennsylvania his home city.

• 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.
