Dr. Chang-Yong Nam is a Scientist (Research Staff 6) at the Center for Functional Nanomaterials (CFN) of Brookhaven National Laboratory (BNL). He is also an Adjunct Professor of Materials Science and Chemical Engineering at Stony Brook University, where he teaches a graduate course and advises graduate and undergraduate students. As a member of Electronic Nanomaterials Group of CFN, he leads a research program focused on developing atomic layer deposition techniques towards microelectronics and energy applications. He also oversees a part of Materials Synthesis and Characterization Facility of CFN. Currently, he is also a lead PI of $8M DOE Accelerate Award Project titled "Angstrom Era Semiconductor Patterning Material Development Accelerator", which aims to accelerate the development of next-generation EUV photoresists via vapor-phase materials synthesis and machine learning correlation between proxy variables and ultiamte EUV patterning performance.
