8/97-cur. University of California at Berkeley, advisor Prof. R. O. Ritchie
Studying the effect of numerous chemical environments and loading conditions on the bulk metallic glass, Zr-Ti-Cu-Ni-Be in order to assess this novel material's advantages and limitations.
Summer 97 Seagate Magnetics Corp., Tribology Research Group
Evaluated the surface spreading kinetics of many polymers that have been considered for use as hard disc lubricants, acquiring the time to repair damage to a thin film of each polymer.
7/95-5/97 University of California at Berkeley, advisor Prof. T. M. Devine
Combined surface enhanced Raman spectroscopy and galvanostatic polarization to evaluate the passive film on iron in borate buffer.
Summer 94 Xerox Corp., Manufacturing Technology Center
Conducted experiments to determine the variables affecting shrinkage in Selective Laser Sintered parts and the feasibility of extrusion as a method for coating fuser rolls for copiers.
Spring 94 Brookhaven National Laboratory, Corrosion Research Group
Performed experiments on the electrochemical process for etching Pt/Ir in chloride solutions and W in caustic solutions with the objective of producing better Scanning Tunnelling Microscope probe tips.
