Brendan O'Connor


Dr. O’Connor is interested in fabrication, characterization, and modeling of organic electronic devices. Organic semiconductors have enormous potential to transform how we interact with electronics, with wide-ranging application opportunities including low-cost solar power, biocompatible electronics, and ubiquitous integration of electronics into our surroundings (the internet of things). Current research interests in Dr. O’Connor’s group include the development of robust flexible and stretchable devices, producing devices with unique capabilities, and establishing scalable processing methods. Devices of interest include solar cells, photodetectors, transistors, and thermoelectrics.

Dr. O’Connor teaches MAE 589 Direct Energy Conversion, MAE 421 Solar Energy, MAE 412 Design of Thermal Systems, MAE 310 Heat Transfer Fundamentals, and MAE 301 Thermodynamics 1.
