Researchers at the University of Waterloo are taking a novel approach to tackle the critical issue of microplastic pollution in water systems. The research team is engineering bacteria that already exist in wastewater to break down Polyethylene terephthalate(PET).

Plastic waste in water systems is an urgent environmental concern. PET plastics degrade into microplastics that adversely impact the ecosystems of our lakes, rivers, and oceans.

Professor Marc Aucoin from the Department of Chemical Engineering and Professor Brian Ingalls from the Department of Applied Mathematics with PhD student Aaron Yip are developing a technique that enables wastewater bacteria to break the links between plastic molecules so PETs can be degraded.

In 2023, Professors William Anderson and Marc Aucoin supervised preliminary research on concussion biomarkers found in bodily fluids, particularly saliva.

Exploring concussion biomarker research

Initially, Shazia Tanvir, a research associate of Anderson’s, began exploring research on concussion biomarkers. She was later introduced to Andrew Cordssen-David, who was a Master of Business, Entrepreneurship and Technology student at the Conrad School of Entrepreneurship and Business at the time.

Cordssen-David was also a former student-athlete who played for the varsity men’s hockey team at the University of Waterloo and had experienced his share of concussions. Recognizing the potential impact of a saliva-based concussion test, Cordssen-David and Tanvir got to work, committing themselves to developing a new concept for a saliva-based concussion screening tool.

A new study by researchers at the University of Waterloo has uncovered a crucial mechanism in the evolution of regulatory systems in E. coli that could have far-reaching applications in cancer therapy and biomanufacturing for products such as insulin or mRNA vaccines.

The critical insight arose when the research team examined a regulatory mechanism near the tail end of a protein called PykF

“A helpful analogy to understand this mechanism is the speedometer in a car. When you're driving through a town, where there are dangers to avoid, you need to know how fast you're going, so the speedometer is important. But, if you're on an open stretch of road with no risks, you can throw the speedometer out the window and put the pedal to the metal,” said Dr. Christian Euler from the Department of Chemical Engineering. “The research opens up the potential to one day put a new stoplight on the road to limit growth rate.”

The Department of Chemical Engineering is proud to announce the appointment of two of its faculty members as Canada Research Chairs (CRC). The designation of Canada Research Chair is an honour bestowed upon exceptional emerging researchers. Professors Valerie Ward and Tizazu Mekonnen are both trailblazers in their respective fields.

Ward now holds a CRC in Microalgae Biomanufacturing. Her research group uses microalgae to make a variety of products.

The highest honour for graduates in the Faculty of Engineering is the Alumni Achievement Medal. Baoling Chen, who completed her PhD in Chemical Engineering in 2015 was bestowed this honour in recognition of her exceptional talent for strategic industry partnership development, mission-driven leadership, and disruptive biotechnology research.
