First principles-based multiscale modeling, synthesis-structure-property relationship of nanostructured materials, surface and interface chemistry, defect and dopant structure and dynamics, semiconductor processing, fuel cells, electrochemical energy storage.
Dr. Hwang's research has an emphasis on fundamentals and applications. Using first principles-based atomistic modeling his research group focuses on developing a better understanding of (1) surface chemical reactions and dynamics, (2) solid-solid and solid-fluid interfacial interactions, and (3) defect nature and formation as well as their role in controlled chemical doping. By incorporating the fundamental knowledge and understanding into larger scale simulations, Dr. Hwang's research group also attempts to solve engineering problems encountered in the fabrication of nanoscale electronic, chemical and biological devices.
The primary goal of Dr. Hwang's research lies in developing (1) strategies for predictive multiscale, multiphysics computational models which can be utilized to guide the rational design and fabrication of next generation nanoscale devices and (2) a detailed understanding of the relationship between the synthesis, structure, and properties of nanostructured materials and systems.
