Linda A. Peteanu has been named head of Carnegie Mellon University's Department of Chemistry. She has served as acting head since January 2016 and succeeds Hyung Kim, who stepped down from the position in the fall of 2015 after serving 14 years as department head. A member of the Carnegie Mellon faculty since 1993, Peteanu is well known for her expertise in applying fluorescence-based methods, including microscopy and electric-field effects, to condensed-phase systems. One focus of her research involves measuring the morphology and electronic properties of molecules used to make light emitting diodes (OLEDs) and photovoltaic cells. Peteanu also applies fluorescence-based methods to the study of nucleic acids as a member of Carnegie Mellon’s Center for Nucleic Acids Science and Technology.
