Stuart Cogan is a Professor in the Department of Bioengineering at the University of Texas at Dallas (UT Dallas), affiliated with the Erik Jonsson School of Engineering and Computer Science. He leads the Neural Interfaces Lab, focusing on materials and devices for chronic neural stimulation and recording. His research emphasizes implantable electrode stability, electrochemical characterization, and minimizing tissue damage.
Education: ScD in Materials Science (MIT, 1979), MS in Materials Science (Duke, 1977), BS in Mechanical Engineering (Duke, 1975). Research interests include neural prosthetics, thin-film electrode fabrication, and long-term implant performance. Key innovations involve amorphous silicon carbide coatings and flexible microelectrode arrays.
Recent work explores electrode materials for chronic use, including iridium oxide and ruthenium oxide, and evaluates their electrochemical stability under stimulation. Studies address mechanical insertion mechanics, parasitic capacitance in arrays, and wireless stimulation systems for peripheral nerves.
Publications span neural interface design, in vivo testing, and material degradation analysis. His lab’s advancements aim to improve chronic implant longevity and therapeutic efficacy in neural prosthetics and neuromodulation therapies.
