5/04 – 5/05   
Center for Nanoscale Science and Engineering (CNSE), Sr. Research Scientist.  Provide metallurgical expertise regarding metallurgy, sample preparation, and evaluation of bulk materials and thin films.  Established and maintain metallurgy laboratory.

9/97 – 5/04 
Assistant Professor, NDSU, Mechanical Engineering Department.  Taught materials courses.  Performed research in materials related to surface engineering: corrosion, wear, surface modification. 

12/91 – 9/97 
Principal Engineer, Babcock and Wilcox, VA.  Provided technical support in materials and manufacturing.  Studied manufacture and performance (corrosion, microstructure, diffusion bonding) of zirconium and nickel alloys.  Studied surface modification techniques.  Performed failure analysis.

6/91 – 12/91  
Assisted Kaiser Engineers, Oakland, CA in the design of underground waste storage tanks located in Hanford, WA. 

6/85 – 6/91 
Resident Engineer, Babcock and Wilcox, in Oregon and Utah.  Responsible for material performance.  Customer representative at Teledyne Wah Chang, Albany, OR and traveled 1 week per month to competitor’s facility, Western Zirconium, Ogden, UT.  Resolved technical issues concerning process manufacturing deviations.  Examined microstructure and determined resulting affects on corrosion performance.

1980 – 1985 
Engineer for Babcock & Wilcox, VA.  Interface with companies that provide metals and machining and testing.  Solved technical problems as they arose within B&W and problems that developed at the vendor that was pertinent to our material or services.  Performed experiments characterizing materials at various process steps, e.g., extrusion and hot rolling.  Utilized statistical software package, SAS, to analyze large data bases.
