Bio

As a fluid dynamicist, I am interested in the flow and rheology of complex fluids. Methodologically, my group conducts research that combines mathematical, experimental, and computational approaches. My research has a wide range of applications, including inkjet printing of paint, waste management in industrial ponds, and cementing processes in oil and gas wells. These systems involve fluids with complex rheology, which can lead to intricate flow behavior. We study the dynamics of these flows and their interaction with nonlinear rheology to address related engineering challenges.

Recent research includes studies of jetting dynamics and drop deposition in high-speed inkjet processes, addressing issues such as overspray from satellite droplets. We also investigate bubble dynamics in complex fluids, motivated by emissions from industrial ponds, focusing on the effects of nonuniformity and time-dependent rheology. Additionally, we examine leakage from oil and gas wells during construction and decommissioning, considering how fluid yield stress influences flow and sealing performance.

Research is carried out in the Thermal Science Lab (12-203) at Cal Poly, in a highly interdisciplinary environment. I welcome opportunities for collaboration and advising on industrial challenges related to complex fluid flows. Interested undergraduate and graduate students are welcome to contact me about opportunities to join my group.
