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).

I joined McMaster in July 2012 following post-doctoral work (in the School of Applied and Engineering Physics at Cornell University) on the development of microscale technologies for biological systems. Prior to that, I completed my Ph.D. (in the Department of Chemical Engineering at The Pennsylvania State University) on the development of membrane filtration processes for DNA purification. Between my undergraduate and master’s degrees I worked in the membrane manufacturing division at ZENON Environmental (now SUEZ Water Technologies & Solutions) on the design and development of hollow-fiber membrane systems for water treatment. In 2014 I was awarded the Young Membrane Scientist Award from the North American Membrane Society and in 2018 I was awarded an Early Researcher Award from the Ontario Ministry of Research, Innovation, and Science. Also, in 2020 I was named the inaugural Education Innovation Fellow by the North American Membrane Society for my work on developing educational initiatives that introduce membrane technologies into the undergraduate engineering curriculum.
