Dr. Robert Cohn

Professor of electrical and computer engineering and director of the ElectroOptics Research Institute and Nanotechnology Center (ERINC)

Dr. Robert Cohn is a professor of electrical and computer engineering at the University of Louisville's J.B. Speed School of Engineering. He also is director of our ElectroOptics Research Institute and Nanotechnology Center (ERINC).

Before UofL, he was a technical staffer at Texas Instruments, focusing on system devices for signal processing, including precision-fabricated surface acoustic wave filters and deformable mirror devices that now are widely used in digital light projectors.

Cohn's research at UofL has included developing video rate calculations and displays for computer-generated holograms. His work has increasingly focused on fabrication of high aspect ratio nanostructures and self-assembly, including of self-assembled freestanding metal alloy nanowires, which were the basis for the spin-off company NaugaNeedles, and self-assembled polymer nanostructures. 

His specialties include:

  • Optical imaging (including tissue optics) and holography;
  • Laser materials processing;
  • And nanofabrication, nanomanipulation/ nanomechanics and nanoscale imaging (e.g. atomic force microscopy and electron microscopy).

Cohn is Fellow of the Optical Society of America for his research on real-time computer holography and in 2000 he received our President’s Award for Scholarship, Research and Creative Activity. He also lays claim to more than 60 refereed journal publications and eight patents, in addition to serving as principle investigator for more than 40 grant contracts. 

Cohn earned his undergraduate degrees in English literature and electrical engineering, along with his master's in electrical engineering, from the University of Kansas. He earned his doctorate in electrical engineering from Southern Methodist University.
