Performed formulation makeup and testing, both analytical and screening, in research and development of Chemical Mechanical Planarization (CMP) slurries.Worked in both R&D, and Commercialization departments on problem resolution and reformulation. Executed table-top polishing for cost effective non clean-room screening including slurry make up, planning, polishing execution, post analysis and summary.Performed analytical testing of developmental slurries both short and long term evaluating stability of size, zeta potential, pH, conductivity, peroxide pot life, and comparative room temperature/oven aging studies.Coordinated with senior scientist, clean room polishing technicians, and pilot plant, for slurry and oxidizer delivery and sampling.

Aurora, Il

Assisted in coating formulation makeup and testing, on lab scale production equipment, in R&D facility directly attached to production. Implemented a raw material retention, and specification validation system that lead to discovery of off spec materials. Prepared developmental paint coatings and padding solutions to produce lab scale products including printable, fire proof, water proof, and tape backing textiles. Tested intermediate and finished products for coating thickness or weight, print-ability, fire proofness, water proofness, and long term weather-ability.Conducted investigations and assisted in problem resolution to production floor issues.Sampled incoming raw materials, collected and documented retains, from raw material drums, and validated density, pH, percent NV solids, and viscosity.

R&D method development on Laser Induced Breakdown Spectroscopy (LIBS) project, including technique development, drafting custom hardware, program user-ability testing, and documentation writing. Assisted post docs in adjoining coatings lab with data collection including Electro Impedance Spectroscopy (EIS) salt cell.Performed method development on LIBS utilizing brass and steel alloys with a range of percent compositions of Cu, Sn, Pb, Zn, and Cr, Ni, Mn, respectively, to create calibration plots for unknown determinations. Acted as end user and tested general operations and program modules, of custom CoatID software, to find errors and suggest improvements.Drafted 2-D layouts for custom LIBS system housing and accessory components, and coordinated with in-house machinist for production.Created PCB CAD layouts, from paper schematics, using Eagle by CadSoft and sent gerber files for fabrication.Composed, edited and designed text and page layout for sections of CoatID user manual.
