Paul Kohl received a B.S. degree from Bethany College in 1974 and Ph.D. from The University of Texas, both in Chemistry. After graduation, Dr. Kohl was employed at AT&T Bell Laboratories in Murray Hill, NJ from 1978 to 1989. During that time, he was involved in the design and processing of electronic packages for Bell system components. He created new chemical processes for silicon, compound semiconductor, and MEMS devices. In 1989, he joined the faculty of the Georgia Institute of Technology in the School of Chemical and Biomolecular Engineering, where he is currently a Regents' Professor and holder of the Thomas L. Gossage/Hercules Inc. Chair. He is the President of The Electrochemical Society and past Editor of Journal of The Electrochemical Society and past founding editor of Electrochemical and Solid-State Letters.

Dr. Kohl's research interests include the design of new materials, processes, and packages for advanced interconnect for integrated circuits and MEMS devices. He is the past Director of the Semiconductor Research Corporation/DARPA Interconnect Focus Center. The goal of this center was to create new technological solutions for future electronic devices. Current projects include creation of new photosensitive dielectric materials for electronic packaging and the design and fabrication of MEMS packages. He also has programs in new approaches to fuel cells and lithium batteries.  The new direct methanol alkaline fuel cells and hybrid alkaline/acid fuel cells have the potential reduced water management and platinum free usage. The integration of high energy density lithium batteries for self-powered integrated circuits and sensors is of interest. Many of these electrochemical devices use ionic liquids as the electrolytes, including the all-sodium battery. Ionic liquids are also being used as the absorber in a new absorption refrigeration cycle. The first ever ionic liquid/fluorocarbon absorption refrigeration cycle has been demonstrated and modeled.

Research Areas of Interest:
  • Photosensitive, low dielectric constant materials for electronic packaging and interconnection
