Our research intersects the multidisciplinary fields of thermal-fluid sciences, interfacial phenomena, and surface science. We study how interfacial and bulk transport processes can be tailored to address challenges in energy conversion, thermal management, and aerospace systems operating under extreme conditions. To achieve this, we combine advanced optical flow diagnostics and thermophysical measurement techniques with micro/nano-fabrication methods to reveal the fundamental dynamics of interface-driven transport processes, in multiphase systems, and across multiple time and length scales.
