The Complex Fluids Laboratory at the University of Toronto works on practical problems driven by curiosity, industrial challenges and scientific and technological issues facing global health and development. Our current research projects are motivated by such diverse areas as mass transport in flows of concentrated suspensions (e.g. drilling muds and blood), kinetics and mass transfer aspects of dissolution of CO2 in switchable solvents, emulsification and drop coarsening mechanisms in oil sands, fabric softeners, embolic ischemia, multiple sclerosis and blood flow. Our long term vision is to make the Complex Fluids Laboratory at University of Toronto a world leader in the characterization of soft-particle suspensions and particle-surface interactions, and in the design of new materials for highly specific applications.

Our laboratory conducts experimental and theoretical studies that elucidate the structure and properties of complex fluids. The complex fluid that is the focus of our lab is the particulate suspension- a mixture of particles with an immiscible fluid. Of specific interest to us are suspensions of soft particles, such as drops, microgels, vesicles and capsules, which are ubiquitous in our day-to-day life and in the industry. Our current studies are focused on both hydrodynamic and non-hydrodynamic (thermodynamic) aspects of the interactions between two soft particles or between a soft particle and a surface, and we are building devices to measure these interactions.
