About

I am a Postdoctoral Fellow at the University of Alberta in the Department of Chemical and Materials Engineering. My research centers on the computational and experimental analysis of multiphase microfluidics, with a focus on flow dynamics in geometrically constricted microchannels. I am actively incorporating AI/ML methodologies into my work, particularly applying Physics-Informed Neural Networks (PINNs) alongside open-source CFD frameworks to validate and optimize multiphase flow systems.
