I am the Research Project Manager in the Nanotribology Laboratory of Prof. Robert W. Carpick, in the Department of Mechanical Engineering and Applied Mechanics, at the University of Pennsylvania. My research at Penn primarily employs a combination of liquid-cell, colloidal-probe atomic force microscopy, nanomechanical characterization and surface analytical techniques to explore functional mechanisms of lubricated nanoscale contacts. A key focus of my research is in identifying viable lubricant additives for the next generation of low-viscosity basestock.

Prior to Penn, I was a Graduate Research Assistant in the Materials Tribology Laboratory, at the Department of Mechanical Engineering, University of Delaware, where I obtained my PhD under Dr. David L. Burris. My thesis research focused on friction and wear mechanisms in molybdenum disulfide, although my doctoral research included various solid lubricants such as diamond-like carbon coatings, alumina-PTFE nanocomposites and aluminum-matrix nanocomposites. Most of the macroscale tribological studies were performed on custom instrumentation, which I designed and fabricated.   

Both my doctoral and postdoctoral research have sought to better understand the operating physical and chemical processes at material interfaces through a combination of multiscale tribometry, mechanical characterization and surface analytical techniques. The overarching goal of my research is to enable system-scale improvements in reliability and efficiency through a better understanding, and therefore, better control of interfacial phenomena.
