Dr. Ahmed AlSayed is a civil and environmental engineer by training, with a strong interest in enhancing the sustainability and resilience of wastewater treatment systems. His work brings together biological process engineering, environmental biotechnology, and data science to tackle real-world challenges in the water sector.

Ahmed is currently an assistant professor in the Department of Civil and Environmental Engineering at Western University. He received his PhD and master’s degrees in civil engineering from York University, where his research focused on high-rate processes for carbon and phosphorus recovery, energy-efficient nitrogen removal, and methane biovalorization using methane-oxidizing bacteria. Following his doctoral studies, Ahmed was an NSERC Postdoctoral Fellow at Northwestern University, where he developed machine learning tools for process modelling and control, and mitigation and advanced research on quantification and mitigation of greenhouse gas emissions from wastewater treatment plants.

Prior to joining Western in 2025, Ahmed contributed to several applied research projects across North America, working closely with utilities, consultants, and academic partners. These projects focused on biological wastewater treatment process intensification, data-driven modelling and process control, and GHG quantification and mitigation. Most recently, Ahmed was part of the R&D team at Veolia Water Technologies & Solutions, where he contributed to pioneering efforts in advancing water and wastewater innovation.

Let's Connect

I’m still very much an engineer who’s curious about how we can connect the dots between data, biotechnology, and infrastructure to build more sustainable and resilient water systems. My work often blends hands-on experimentation with data-driven approaches, aiming to solve real-world problems in wastewater treatment.

If you’re a prospective MSc or PhD student interested in working at the intersection of environmental biotechnology, process engineering, and machine learning, I’d love to hear from you. I’m especially excited to work with curious, persistent and resilient students.

I also welcome collaboration with academic and industry partners. Whether you're exploring new technologies, trying to optimize existing systems, or looking to integrate data into operations in meaningful ways—let’s talk. I believe in applied, curiosity-driven research, and I’m always open to new ideas and perspectives.

Feel free to reach out if any of this resonates with you. Let’s see what we can build together.
