Our Department ranks as number one in Canada for Chemical Engineering according to the U.S. News and World Best Global Universities.
The department's small class-sizes, engaging teaching practices, and hands-on learning in our state-of-the-art facilities empower our students to solve real-world problems.
The Department of Chemical Engineering is a vibrant center of collaborative research addressing some of the most pressing challenges in energy and materials. Our faculty members are engaged in a diverse array of research in areas such as machine learning and process systems engineering, CO2 capture and conversion, polymer engineering, renewable energy, synthetic biology, environmental remediation, and materials science that push the boundaries of innovation.

Pendar Mahmoudi wins two teaching excellence awards
The Department of Chemical Engineering is proud to announce that Professor Pendar Mahmoudi is the 2025 recipient of the Faculty Teaching Excellence Award and the Boyce Family Teaching Award.
"I feel truly honoured and humbled to win these awards. Getting rewarded for a job I enjoy is a blessing. I am extremely thankful for the support of my colleagues in the department, who will happily listen to new ideas or issues and offer assistance or advice," says Mahmoudi.
The Faculty Teaching Excellence Award is adjudicated by program chairs and directors, whereas the Boyce Family Teaching Award is a student-driven award.
Although judged by very different groups, they both reached the same conclusion that Mahmoudi’s teaching methods successfully incorporate experiential learning, innovative teaching and commitment to student connection and success.
Mahmoudi began teaching in 2018 after finishing her PhD at the University of Waterloo. It was during her graduate studies that she discovered her passion for teaching.
A greener future for personal hygiene products
A chemical engineering research group led by Professor Tizazu Mekonnen has developed an eco-friendly super absorbent hydrogel that could dramatically reduce the environmental impact of personal hygiene products like diapers, menstrual pads and tampons.
Unlike current products, which take centuries to break down, this new material degrades harmlessly in soil within three months.
In North America, billions of disposable diapers end up in landfills annually, according to the U.S. Environmental Protection Agency (EPA) taking up to 450 years to decompose.
Around 1.8 billion women menstruate monthly, and most single-use menstrual pads and tampons also end up in landfills. These products are about 90 per cent plastic and can take up to 500 years to break down, according to the United Nations Environment Programme.
Chemical engineering team excels in circular water economy challenge
A team of graduate students from the Department of Chemical Engineering earned an impressive second place in the WEF Technical Exhibition and Conference (WEFTEC).
The student team, supervised by Professor Sarah Meunier, first won the Water Environment Association of Ontario (WEAO) competition. The contest, a municipality that provides a current and relevant problem. After that the team, sponsored by WEAO moved on to a second-place win at WEFTEC.
WEFTEC is the largest water quality exhibition in North America, and they hold an annual international student competition. The University of Waterloo team, which included Joseph Wortman, Rosa Maria Castillo, Maryory Ocana and Jinxuan Zhang competed against students from universities from across North America in the new Circular Water Economy category.
The teams were tasked with optimizing a wastewater treatment plan in Barrie. One of the biggest real-world hurdles is that Barrie expects its population to double by 2051, but the treatment plant itself has no room to grow.

PhD Thesis/Transport and Irreversible Retention of Hydrophobic Nanoparticles by Fluid-Fluid and Fluid-Solid Interfaces in Porous Media by Youssra Rahham
Thesis Title: Transport and Irreversible Retention of Hydrophobic Nanoparticles by Fluid-Fluid and Fluid-Solid Interfaces in Porous Media
Abstract:
Hydrophobic nanoparticle (NP) transport in porous media has implications for aquifer transport and retention of a wide range of contaminants that infiltrate water resources and threaten human health as well as aquatic environments. Comprehension of NP transport and interactions with hydrophobic surfaces and interfaces -given their ubiquity in porous aquifers- is essential for groundwater remediation from organic contaminants, toxic engineered NPs, and nanoplastics.
This research investigates the transport and attachment of hydrophobic NPs under varying physicochemical conditions in saturated and unsaturated porous media by integrating experimental observations across multiple scales, theoretical extended-DLVO predictions, and numerical modeling. A non-toxic, negatively-charged, hydrophobic model NP system synthesized from ethyl cellulose (EC), and exhaustively characterized for colloidal stability and interfacial interactions, was employed to systematically explore NP interactions with fluid-fluid and solid-fluid interfaces.
The upscaling capability of an advection-dispersion-retention continuum model was compared vis-à-vis a pore network model of irreversible NP attachment onto fluid interfaces in 3D columns packed with spherical glass beads, showing that the latter captures key pore-scale dynamics such as bypassed interfaces, slow-moving corner flows, and diffusion-dominated retention.
Transport experiments in 2D microfluidic pore networks confirm that the dynamics of NP retention in unsaturated porous media depend not only on the saturation of the non-wetting phase, but also on its connectivity and the accessibility of immobile fluid-fluid interfaces.
