Why did you decide to study engineering?

I was interested in engineering when I was a high school student, although I didn’t know what kind of engineer I wanted to be. Chemical engineering is where I started, and once I began graduate school I gravitated to environmental engineering and research.

Tell us about your research on water treatment.

My research focuses on finding ways to ensure water is safe to drink, particularly in Indigenous and rural communities.

"Globally, nearly two billion people do not have access to safely managed drinking water, and some of those people are here in Canada."

Around 20 per cent of the country’s population lives in rural areas and their water is at greater risk of being contaminated than water in urban areas. Many remote communities do not have adequate water treatment infrastructure, or the existing infrastructure has not been properly designed or maintained. My research aims to develop water treatment solutions that are effective and robust, yet simple to operate.  

One other important aspect of my research is finding ways to remove PFAS – per- and poly-fluoroalkyl substances– from drinking water. These chemicals are found in many everyday products, and they have a range of potentially dangerous health and environmental impacts. They are aptly known as forever chemicals and eliminating them from drinking water is therefore very challenging.

How do you work with communities to develop effective solutions that make a difference? 

"A holistic and collaborative approach is required to develop technical solutions that meet the specific needs of each community."

Having technology that is appropriate for a small community is one thing, but making sure that technology is accepted by its members and that it works in that setting is another.  

By engaging with communities early on, the solutions we develop are far more likely to be accepted and sustainable over the long term. Historically, engineers or governments often parachuted in solutions that were not aligned with a community’s needs. My research group works to overcome this challenge by bringing together the rightsholders and stakeholders to not only identify the problems, but also participate in co-creating the appropriate solution.

How do your water treatment solutions work? 

"The technology we’re developing for smaller communities needs to be simple and effective. That’s actually very hard to do and requires us to be innovative and creative."

One approach we’re taking is to use nature as our inspiration. Knowing that contaminants in the environment are naturally degraded by bacteria and sunlight, we can explore how to mimic those qualities to eliminate contaminants in drinking water. An example would be developing devices that emit ultraviolet light to eliminate microbes from water. 

Are these water treatment solutions being used? 

Yes. Over the past few years our solutions have helped eliminate or lift water advisories in more than 10 communities in British Columbia and one in Ontario.

What courses do you teach? 

I teach second-year courses on engineering design and environmental sustainability and a third-year course on water pollution control. I also teach at the graduate level and in the Master of Engineering Leadership program in Integrated Water Management.  

What skills do you think students need to develop to have an impact as engineers? 

"My students are learning both the technical and social skills needed to develop solutions, and they’re seeing the positive impact technology can have on individuals and society."

Co-op students in my lab work directly with people in impacted communities to learn what their needs are. When they come back to the lab or classroom they have a much better understanding of the community’s needs and how to go about solving the problems to have a positive impact in society.
