University of North Texas, Denton, TX. 5/10-5/14: Associate Professor, Department of Materials Science and

Engineering, University of North Texas, Denton, TX. 9/05-5/10: Assistant Professor, Department of Materials Science and

Engineering, University of North Texas, Denton, TX. •Established a materials tribology laboratory to measure friction,

wear and lubrication processes by in situ and ex situ methods. •Constructed a viscous flow atomic layer/chemical vapor deposition reactor to synthesize solid lubricant and wear resistant coatings for moving mechanical assembly applications. •Secured several external federal grants (listed under current funding). •Developed two new courses: Bonding, Structure and Crystallography and Tribology of Materials.

6/06-8/06; 7/07-8/07; 7/09-9/09; 6/11-7/11, 7/12-8/12, 6/13-8/13 & 6/14-8/14: University Summer Faculty, Microsystems Materials, Tribology, & Technology (2006 & 2007), Multiscale Metallurgical Science &

2

Technology (2009, 2011 & 2012), and Materials Aging and Reliability Departments (2013 & 2014), Sandia National Laboratories, Albuquerque, NM. •Investigated solid lubrication mechanisms in diamond-like carbon, lubricious oxides and MoS2/Sb2O3/Au nanocomposite coatings for applications in moving mechanical assemblies, such as weapon system components, microsystems, and space (satellite) components. •Studied high temperature wear behavior and mechanisms of Tantalum- and Cobalt-based alloys.

6/03-9/05: Limited Term Member of the Technical Staff, Microsystems

Materials, Tribology, and Technology, Sandia National Laboratories, Albuquerque, NM. •Co-developed a new process for the deposition of crystalline tungsten disulphide (WS2) solid lubricant coatings with monolayer precision by atomic layer deposition (ALD) for potential applications in moving mechanical assemblies such as MEMS (SMM and LIGA) and rolling element bearings. •Investigated the coverage, friction, and wear behavior of PECVD diamond-like carbon (DLC) and diamond-like nanocomposite (DLN) coatings for potential applications in low mass mechanisms and LIGA technology. •Characterized the self-mated tribology of ultrananocrystalline diamond (UNCD) thin films for potential applications to MEMS resonators.

6/00-6/03: Postdoctoral Research Associate, Tribology Section, Naval

Research Laboratory, Washington, D.C. •Investigated the friction and wear life under dry sliding of amorphous diamond-like carbon (DLC) coatings using the NRL homebuilt in situ Raman tribometer. •Developed a model for quantifying the thickness of thin coatings and wear scars using Raman spectra in spot and line modes. The calculated thickness compared well with stylus profilometry values and complement it by determining thickness, not physical height. •Investigated lubricated sliding wear of DLC in Krytox lubricant with in situ Raman tribometry. The Raman carbon (DLC coating) and silicon (substrate) signals were monitored during sliding using a line scan attachment. It was determined the coating wears linearly until failure based on increasing Si:C intensity ratios. The in situ Raman line map profiles inside the wear track showed the coating wore unevenly based on mapping Si to C intensities, and there were no detectable transfer films inside the contact, just a hydrodynamic boundary film.

1/95-6/00: Research Assistant/Teaching Assistant, Department of Metallurgical and Materials Engineering, The University of Alabama. •Designed and constructed a dual ion beam assist technique in high vacuum to deposit ultrathin hard coatings and solid lubricant films. •Demonstrated experimentally that discrete amounts of substitutional nitrogen incorporated into dc/rf sputtered and ion beam deposited diamondlike carbon thin films dramatically improve the resistance to wear, resistance to plastic deformation, and lower the friction coefficient.

•Determined that depth-sensing reciprocating scratch tests on protective overcoats can produce repeatable and accurate wear and friction properties down to 20 Å film thickness. •Performed the first set of experiments to compare different contact loading regimes on the wear and friction properties of ultrathin films using Nanoindenter II nanoscratch option and an IBM home-built microwear scan technique. •Developed a technique to measure ultrathin (<50 Å) film coverage of underlying magnetic media using Angle-Resolved XPS. •Conducted extensive depth-sensing nanoindentation measurements of many mechanical properties of thin films including hardness, elastic modulus, and strain-rate sensitivity. •Experienced in many structural characterization techniques including high and low angle x-ray diffraction, FE-SEM with EDXS, AFM, spectroscopic ellipsometry, XPS/VBXPS/AES, Raman spectroscopy, and Fourier transform IR spectroscopy.

1/99-6/99: Research Scientist/Engineer, IBM, Almaden Research Center, San Jose, CA.

•Conducted extensive wear testing using an unique IBM built system on 10 (first time reported) to 60 Å thick protective overcoats on rigid disks, e.g., ion beam deposited CHx, CHxNy, CNx, sputtered CHx, CNx, BCx, BCxNy, SiNx. •Established a new wear rate ranking methodology for sub 60 Å thick overcoats with 1 Å resolution using Auger electron spectroscopy measurements within the wear track. •Analyzed the effects of biasing, ion energy, nitrogen concentration and depositing seed layers on mechanical wear strength and friction. •Determined experimentally by AFM and HRSEM that the failure mechanisms are different for ultrathin 10 and 20 Å sputtered overcoats. •Ascertained correlations between the adhesion strength and microstructural measurements, namely density (XRR) and sp3 content (NMR), of ultrathin overcoats.
