Stuart Cogan joined the UT Dallas faculty as a professor of bioengineering in 2014. In 2016 he was inducted into the American Institute for Medical and Biological Engineering College of Fellows for "outstanding contributions to the understanding of the electrochemistry and properties of neural stimulation and recording electrodes.” Dr. Cohen is also the Principal Investigator for the Neural Interfaces Laboratory at UT Dallas. His research interests focus on materials and devices for stimulation and recording of the nervous system with the goal of "the development and characterization of materials and devices that are stable in long-term chronic implants and that safely provide therapeutic levels of stimulation." This includes:

  • the fabrication of thin film multielectrode devices,
  • the development of implantable encapsulation,
  • electrochemical characterization and long-term testing in the laboratory and in vivo, and
  • the study of stimulation-induced electrode and tissue damage mechanisms.
