Research Interests
My research is focused on decoupling complex synthesis processes by integrating plasma-based nanoparticle generation with advanced reactor design. I'm interested in leveraging computational fluid dynamics (CFD) and in-situ diagnostics to control aerosol dynamics, catalyst evolution, and the synthesis of high-performance nanomaterials.
