Professional History
Lexmark International- Research and development division- Lexington, KY
Research / Chemical Engineer
Supplies Engineering
July 2006 – October 2014
Latex (for uses in toner) formulation development
• Developed styrene-acrylate latex formulations
o Designed to duplicate material from vendor
o Decrease single sourcing complications
• Designed experiments to optimize latex formulation
• Designed experiments to optimize latex processing
• Designed experiments to correlate latex properties to final product properties
• Created “quick response” screening test of latex materials for use in the toner
process
Improving robustness of rubber roller printer component
• Instrumental in choosing metal catalytic materials
o Current iron-based catalyst does not result in stability of roller material
across environmental changes
• Created formulations for rubber roller using alternate catalyst material
• Created molded rubber buttons to test rubber physical properties
“Green” coating materials’ development
• Developed water-based, polyurethane coating formulation for rubber roller
printer component
• Developed process for coating application on rubber roller printer component
• Executed trials to functionally test new coating material
• Selected for Research and Technology Symposium Presentation
o “Waterborne Coatings”
Lexmark Research and Technology Symposium
Lexington, KY
Failure analysis in printing
Identified material change that caused severe failure in printing
•
o Component of interest: semi-conductive rubber roller
Lead on functional testing to confirm hypothesis (of material change)
•
Lead on developing process for improved rubber roller component
•
Successfully scaled-up process for manufacturing
•
Lexmark International- Materials supplies division- Lexington, KY
Supplies Engineer
New Rubber roller qualifications
• Lead the screening process for potential failure from coating formulation
changes
• Lead the screening process for potential failure in coating process changes
• Developed off-line testing technique for determining failure potential from
formulation and/or process changes in the coating material
New Product Qualifications
• Instrumental in development and qualification of in-house coatings for rubber
roller for cost savings and second source potential
• Lead of determining coating impacts on print quality
Qualification of process changes
• Headed the testing/ qualification for production processing changes to reduce
production time and improve through-put
• Determined risk for implementing production process changes on print quality
Once Upon a Child –Management position- Lexington, KY
Store Manager
July 2003 – May 2005
• Responsible for hiring and training new employees
• In charge of payroll and accounting for two stores
• Created employee incentive plans
• Overseeing purchase of product for the store
