Group Members

sarmi.jpgSarmishtha Sircar: A PhD student (EME) whom joined the group in Fall 2008 and expects to defend her PhD in 2013.  Sarmishtha has published papers in diffusion into expandable metal organic frameworks (with Prof. Jing Li of Rutgers), and has recently submitted a very rigorous analysis of high-pressure differential adsorption methodology.  We expect her third and fourth papers (which concern adsorption and diffusion into expandable metal organic frameworks) soon!

chengyu.tifCheng-Yu Wang: A PhD student (EME; minor chemical engineering) working on incorporating catalysts into metal-organic frameworks, and other basic studies of the hydrogen spillover phenomenon. Cheng-Yu joined the group in Summer 2010, and his expected graduation date is early 2014. He has presented at several DOE conferences, and is expecting his first authored publication in a few months. He came to the group with significant research experience at the Institute of Nuclear Energy Research in Taiwan, where he also studied materials for hydrogen spillover.  Cheng-Yu expanded group expertise into MOF synthesis and doping, adsorption characterization, and very rigorous combined adsorption/temperature-programmed desorption experiments.
