Research Interests

The overarching theme of my research group is the development and optimization of novel separation processes.  Toward this end, we typically focus on microscale processes (MSP) - the study of conventional processes (e.g. chromatography, membrane filtration, adsorption) but in miniaturized formats such as micro-columns, micro-well plates, and microfluidic devices. The advantages of this approach are considerable - it is extremely cost-effective since it requires minimal amounts of material and it is very efficient since it uses a parallel architecture approach. Our research uses a unique combination of experimental work, statistical analysis, and advanced tools for sample characterization and process modelling.

Microscale processing in environmental engineering:

We are developing novel separation processes for a variety of 'tough-to-treat' applications including tailings (i.e. suspensions of clay particles) from mining operations, biosolids from municipal WW treatment, and vegetable 'wash-water' from agricultural processing.  Our work includes both physical, chemical and biological-based processes including the development of the first ever high-throughput microscale stirred cell filtration device for flat sheet membranes, the first ever high-throughput microscale filtration device for hollow fiber membranes, a lab-scale anaerobic digester featuring recuperative thickening technology.  Our lab is home to the Micro-scale Separations and Analysis Suite (MSAS), a collection of specialized equipment that is essential for the execution and analysis of micro-scale experiments, that was supported by the Canada Foundation for Innovation (CFI), Ontario Research Fund (ORF), and NSERC Research Tools and Instrumentation (RTI) programs.

Downstream purification of oncolytic viruses:

We are working to solve the considerable challenges associated with the downstream purification of oncolytic viruses (OVs), an innovative anti-cancer therapeutic that has attracted considerable attention. The establishment of a cost-effective OV manufacturing process is critically dependent on the development of new technologies for downstream processing - the finished product must be of a sufficiently high purity and immunogenic activity (to fulfill regulatory demands) that is ready for clinical trials and full-scale commercialization.  This work is being done in collaboration with scientists at the Ottawa Hospital Research Institute and University of Toronto through the Alliance for Biotherapeutics Manufacturing Innovation (ABMI).
