"Particle technology is ubiquitous in essentially all industries that employ chemical engineers but it is almost absent in the chemical engineering curriculum. I am working with numerous regular and adjunct faculty to correct this educational gap by developing and teaching the Masters of Engineering in Particle Technology (MEPT). This program provides this important skill set and knowledge base, valued by industry but generally unavailable in one place or with such singular focus. Our focus is on developing and refining a comprehensive curriculum that sets the standard for particle technology education globally.

While I currently do not have an active research program, my research interests include granular flow and segregation, particle size enlargement through binder granulation, and particle characterization."
