Professor Benziger's interests are in chemical reaction engineering and catalysis. His recent work has focused on reactors for organic vapor deposition for electronic devices, design, operation and control of Polymer Membrane Fuel Cells, and new reactor processing for sulfur removal from petroleum. In collaboration with Professor Steve Forrest Professor Benziger and has developed new reactor designs for the successful implementation of continuous large scale process of organic thin films for OLEDs and patterning methods with Organic Vapor Phase Jet Deposition. This work has successfully demonstrated the key design and control parameters for OVPD and OVJP key to the demonstrations of these techniques by Professors Forrest’s and Benziger’s groups.

In the Fuel Cell area Professor Benziger’s group has developed new reactor configurations for Polymer Electrolyte Membrane Fuel Cells that provide the essential information for controlling the dynamic behavior of PEM fuel cells. This work has demonstrated the existence of steady state multiplicity in PEM fuel cells along with a key discovery of the coupling of the chemical reaction in the fuel cell with mechanical relaxation processes in the polymer membrane.

Professor Benziger and his group has also demonstrated a new sulfur recovery process for hydrocarbons streams that operates at low temperature and with has very low energy requirements. Professor Benziger has been a part of the Borexino Solar Neutrino collaboration where he has led the group that developed the methodology and equipment to purify multi-ton quantities of liquid scintillator. Professor Benziger co-authored over 100 papers in refereed journals, and given over 50 invited talks on subjects related to surface reactivity. He has received the Exxon Award in Solid State Chemistry from the Inorganic Chemistry Division of the American Chemical Society, and the Purdy Award from the American Ceramic Society.
