Dr. Chang-Yong Nam is a Scientist 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 students. Dr. Nam received his Ph.D. in Materials Science and Engineering from the University of Pennsylvania in 2007, studying the synthesis and electronic device applications of GaN nanowires (with the late John E. Fischer). Dr. Nam joined BNL in 2007 as a Goldhaber Distinguished Fellow (with Charles T. Black), working on organic photovoltaics. Since then, he has risen through the ranks to Scientist. As a member of Electronic Nanomaterials Group of CFN, he leads a research program centered around atomic layer deposition techniques towards micro/nanoelectronics and energy applications. He also oversees a part of Materials Synthesis and Characterization User Facility of CFN.
