Sustainability Changemakers Showcase

The Sustainability Changemaker Showcase! is a special event highlighting the groundbreaking research of three graduate students selected from the SEDTalks! series. These students have been recognized for their innovative work advancing sustainability in engineering and design.

As part of a TISED initiative, the event will feature TEDTalk-style presentations from our three Changemakers, followed by a live Q&A session, where you'll have the opportunity to engage with them directly.

The event is free to attend, with doors opening at 5:00 pm. After the presentations, join us for a cocktail reception—an excellent chance to connect with the Changemakers and fellow attendees.

Meet our Changemakers

Hoda Ahmed

Hoda Ahmed 

PhD Candidate, Mining and Material Engineering 

Supervisor: Prof. Jinhyuk Lee

Title: A Dash of Salt for more sustainable batteries 

Using renewable energy to charge batteries is a great environmental step forward, but the batteries themselves need to be made greener too.  Hoda’s work uses manganese-based disordered rock salt (Mn-DRX) cathodes to replace Cobalt ones. This innovative approach synthesizes single-crystal nanoparticles smaller than 500nm, maintaining regular morphology and substantially improving the density and stability of Mn-DRX cathodes. 

Steven Walker

Steven Walker 

PhD Candidate, Chemical Engineering

Supervisors: Prof. Sylvain Coulombe and Prof. Jan Kopyscinski

Title: Making Natural Gas out of Thin Air  

If natural gas can be produced by reacting captured carbon dioxide (CO2) in the atmosphere with green hydrogen; the process would be carbon neutral. For this process to work an efficient catalyst is needed to increase the conversion of CO2. Steven’s research explores producing carbon neutral natural gas using a unique catalyst that looks like a Twizzler covered in Nerds but 1000 TIMES SMALLER. 

Saadia Wasim

Saadia Wasim 

PhD Candidate, Civil Engineering 

Supervisor: Prof. Stephanie Loeb

Title: A ray of sunshine for cleaner water 

Modern water treatment methods are effective, yet they require expensive infrastructure and have high operating costs making them incompatible with rural Africa, the area in the world that needs it most. Saadia’s research is developing a low-energy, low-cost solution via solar powered plasmonic-photocatalytic nanoparticles to remediate contaminated in water. This work helps in developing a sustainable solution for communities in resource limited regions.
