My research program is focused on solving problems that involve transport of heat, mass, and momentum in a wide range of applications including film growth for energy-efficient electronic devices, novel material processing for photovoltaic applications, and nanomaterials for treatment of cancer. Our recent effort is focused on the behavior of nanofluid transport in porous structure such as tissue and fiber matrix using a multi-scale approach. My team has developed a multi-physics model that considers particle-surface interaction as well as macroscale particle transport in fluid and tissue deformation using finite volume, particle tracking, and meshless methods. We have used this model to study the flow and deposition of nanofluid in tissue during an intratumoral infusion process that involves complex physicochemical processes with large disparity in length and time scales. This multi-scale approach can be applied to target drug delivery using nanocarriers and nanofabrication with colloidal fluids. I am also interested in novel material processing for energy-efficient electronic devices and low-cost photovoltaic facilities. My research group has developed models to study fluid flow, heat and mass transfer, phase change, chemical reaction kinetics, and electromagnetic heating involved in Chemical Vapor Deposition, Physical Vapor Transport, Directional Solidification, and Liquid Composite Molding. These models have been used to study the growth of silicon carbide film from vapor phase, solidification of bulk multi-crystalline silicon, and growth of silicon wafer on substrate. Information obtained through the simulations allows material scientists to link growth conditions to growth rate, defect formation, and material properties, and ultimately, lead to improved system design and optimized processing conditions.infiltration_2
