Professor of Chemistry
Christian M. Rojas, Professor of Chemistry, joined the Barnard faculty in 1997 after completing an NIH Postdoctoral Fellowship at the Massachusetts Institute of Technology and the Scripps Research Institute.
Professor Rojas's research interests focus on new methods for incorporating nitrogen into organic molecules and application of these methods to the synthesis of amino sugars.
His work is currently supported (2014-2017) by a National Institutes of Health (NIGMS) grant entitled: "Construction and Union of 2-Amino Sugar Building Blocks." Previous Barnard undergraduate student researchers from the Rojas group have gone on to careers in science, teaching, and medicine, including positions in the pharmaceutical industry, academia, public-school teaching, public health, and government.
