My research interests lie at the intersection of advanced computational fluid dynamics, with particular emphasis on free-surface and open-channel and groundwater hydrodynamics, near-wall boundary layer behavior, microfiltration processes, and applications in nanofluidics.

In my recent work, I utilized high-fidelity Computational Fluid Dynamics (CFD) simulations to explore the biophysical ecology of salmon redds (nests), aiming to explain the intricate interactions among surface hydraulics, redd morphology, sediment permeability, riverbed roughness, and egg-pocket location. This research provides critical insights into how these physical parameters influence hyporheic exchange flows—subsurface flows that govern the delivery of oxygen and nutrients essential for the development and survival of salmonid embryos. Recent results have contributed to a broader understanding of ecohydrological processes and informed river restoration efforts targeting aquatic habitat sustainability.

My work also includes "Wetting Properties and Re-entrant Geometry of Nanotextured Interfaces" and "Microfiltration of Oil-in-Water Emulsions,".
