Research interests + projects

Transdisciplinary Climate Emergency

Exploring complex systems around low carbon futures through transdisciplinary approaches. Collaborating and co-creating with others to advance environmental literacy in higher education and connect with communities and other partners to imagine change. Ongoing curiosity about how collective and relational efforts may help us understand the patterns of interactions and ultimately catalyze effective movements towards hopeful futures.

Transdisciplinary PhD Collaborative on Climate Emergency 


Carbon Capture, Utilization and Sequestration (CCUS) Implementation

Connecting with academic, public, and private stakeholders on knowledge translation and mobilization for regional and national decarbonization strategies. Integrating processes and technologies for carbon circular economy.

British Columbia CCUS Visioning Workshop


Multiphase Systems and Reaction Engineering

Understanding the hydrodynamics of fluidized beds as critical to the design and scaling of fluidized bed reactors that are used as various reactors. Deploying various measurement techniques and modeling methods to study and predict the behaviour of fluidized beds and other multiphase reactors. Fluidized bed applications include biomass utilization for energy production and carbon capture through looping systems.
