My research interests are in developing and understanding materials used in various photovoltaic and light emitting devices. My on-campus research develops structure-property relationships connecting molecular properties, bulk morphology, interfacial morphology, and solid-film optoelectronic properties in small-molecule organic thin films. This research includes the use of atom probe tomography to understand fundamental science and improving device efficiency in small-molecule organic light emitting diodes and small-molecule organic photovoltaics. My other research interest, primarily with collaborators at NREL, is the integration of III-V materials with silicon for optoelectronic platforms such as photovoltaics.

My research interests revolve around using insights gained from Atom Probe Tomography (APT) to engineer more efficient, longer-lasting organic semiconductor devices. Using APT data as feedback on the structure of layers and interfaces in these devices, important design flaws can be identified and modified to better suit the device’s intent. For example, chemical degradation products can be identified and located spatially within a device to help understand the degradation process and how better design can help avoid or slow it. If dopants which are assumed to be well dispersed actually tend to aggregate, potential solutions to this problem can be tested in APT and correlated with device performance to determine how nanometer-scale structure and molecular distribution affects device properties.
