Dr. Conron’s area of expertise is physical organic chemistry, with an emphasis on the physical characterization of electron transporting materials for use in energy conversion and storage. She has experience with synthesis of organic dyes and artificial photosynthetic systems, and she specializes in design and performance analysis of organic photovoltaics.

Dr. Conron has experience with a wide variety of physical characterization techniques including UV-Visible spectroscopy (UV-Vis), photoluminescence (PL), PL lifetime, electrochemistry (CV, DPV), transient absorption spectroscopy, small- and wide-angle X-ray scattering (SAXS/WAXS), spectroscopic ellipsometry, and atomic force microscopy (AFM). Additionally, Dr. Conron is versed in standard organic synthesis and purification methods [flash chromatography, gel-permeation chromatography (GPC), size-exclusion chromatography (SEC), high-pressure liquid chromatography (HPLC)], molecular characterization [nuclear magnetic resonance (NMR), infrared spectroscopy (IR), mass spectroscopy (GC-MS, LC-MS, MALDI-TOF)], and methods of organic thin film fabrication including spin coating and vacuum thermal evaporation.

Prior to joining Exponent, Dr. Conron worked as a postdoctoral research associate at the University of Southern California where she specialized in fabrication, analysis, and optimization of organic photovoltaics incorporating novel electron transporting dyes. At USC, she also studied interfacial dynamics and surface characterization of vapor- and solution-deposited organic solids. Before working at USC, Dr. Conron’s Ph.D. research focused on synthesis and characterization of artificial photosynthetic systems for use as light harvesters and electron transporters. She analyzed the solution-phase electron transport properties of organic donor-acceptor systems, nanoscale aggregates, and DNA hairpins.
