Bio

I am an applied physicist who is adept at characterizing materials, analyzing processes, and solving problems. My area of specialization is in experimental polymer physics and rheology, with a focus on materials and interfacial science. I worked as an industrial physicist for 17 years in R&D at Eastman Kodak and Bausch and Lomb.

I've built structure-property models to improve the on-eye comfort of contact leses and studied how branched polymer architecture impacts manufacturing and product performance for inkjet inks, electrophotographic toners, photochemical coatings, and extruded plastics. I've designed and built custom experimental equipment to learn about the flow and deformation of polymer melts and colloidal suspensions and polymer solutions. I've also modeled how the mechanical properties of polymer films, and the tribology of hydrogel networks, impact product features in consumer products.

Since the fall 2014, I have been a Lecturer in Physics at RIT.

Currently Teaching

PHYS-212
4 Credits
This course is a continuation of PHYS-211, University Physics I. Topics include electrostatics, Gauss' law, electric field and potential, capacitance, resistance, DC circuits, magnetic field, Ampere's law, inductance, and geometrical and physical optics. The course is taught in a lecture/workshop format that integrates the material traditionally found in separate lecture and laboratory courses.
PHYS-365
3 Credits
In this course light waves having both amplitude and phase will be described to provide a foundation for understanding key optical phenomena such as interference, diffraction, and propagation. Starting from Maxwell's equations the course advances to the topic of Fourier optics.
