About R. Bertrum Diemer

My primary object as Professor of Practice is the development, teaching and oversight of the new professional masters program leading to a Masters of Engineering in Particle Technology degree. While particle technology is practiced throughout the process industries, and is the focus of programming in professional organizations such as AIChE through its Particle Technology Forum, it is not taught in a focused way in the chemical engineering curriculum. I am working with numerous other regular and adjunct faculty to close this gap. My partner in this endeavor is Prof. Jim Michaels. I also have primary responsibility for teaching the capstone design course to senior undergraduates.

While I am not currently directing a research program, I serve on the dissertation committee for a doctoral student employing population balance methods in the understanding of complex colloidal rheology. My research interests include advanced population balance modeling techniques, gas-to-powder conversion processes, particles as photochemical reactors, high-temperature thermochemistry, inorganic solid-liquid equilibria, and chemical reaction engineering.
