My current research focuses on the characterization of surfaces using x-ray photoelectron spectroscopy (XPS). Most recently, I have been involved in two projects involving the biofunctionalization of various surfaces for selective protein binding. In addition, I have looked at adhesion behavior of a therapeutic monoclonal antibody to various bio-relevant surfaces. I have also been a part of many other projects, performing XPS to characterize a variety of samples, including Si and C nanowires, isotopically-enriched Si, and atomic layer deposited H3N4 and TiN films. Prior to my surface study work, I used planar laser induced fluorescence (PLIF) and optical emission techniques to investigate the gas-phase chemistry behavior in fluorocarbon plasmas used in semiconductor oxide etching. I also serve as the caretaker of the multi-user XPS instrument and am the laser safety representative for my division.
