  • Metalworking Fluid Purification and Life Extension
  • Microfiltration Processes
  • Micro-scale Manufacturing Processes



John joined the University of St. Thomas in 2009 with the goal of developing engineering graduates that have a global perspective of engineering as well as being technically excellent.  Before joining St. Thomas, John was a postdoctoral research associate at the University of Illinois where he worked on various projects related to fluid dynamics and sustainable manufacturing such as the development of a 2nd generation atomization-based cutting fluid application system for micro-machining and the development of a three dimensional fluid dynamic model of membrane fouling of ceramic microfiltration membranes in metalworking fluid purification.  His work has led to multiple journal papers and conference presentations and the writing of funded grant proposals from the National Science Foundation and the Illinois Sustainable Technology Center. While at the University of Illinois, John taught Introduction to Manufacturing Systems and Eco-Design and Environmentally Conscious Manufacturing, a course he developed.  Prior to earning his doctorate John worked as a Transportation Design Engineer for the City of Tulsa.
