In recognition for his devotion to advancing research, intellectual merit, and benefiting the broader impacts to society, the Department of Mechanical Engineering recognized Dr. John Greenhall with the 2017-2018 Outstanding Dissertation Award. Advised by mechanical engineering associate professor Bart Raeymaekers, Greenhall was a member of the Utah Tribology and Precision Engineering Laboratory, while earning his degree. Currently he is a post-doctoral researcher at Los Alamos National Laboratory, Los Alamos, NM.

Greenhall’s dissertation entitled, “Three-dimensional printing engineering materials via integration of ultrasound directed self assembly with stereolithography,” has implications in a wide range of applications including 3D printing composite material structures with high mechanical strength and/or embedded electrical wiring and manufacturing metamaterials for acoustic and electromagnetic cloaking and sub-wavelength imaging.

Committee member mathematics associate professor Fernando Guevara Vasquez said, “John’s thesis was impressive by the breadth and creativity of the approaches he used to control particles with ultrasound waves with application to 3D printing.  John is fearless and didn’t shy away from experiments, simulations or even mathematical analysis. I consider myself fortunate to have collaborated with John!”
