Work Experience
Exatec, Division of Sabic Innovative Plastics, Wixom, MI, 2006 – 2011
After graduating in 2006, Dr. Gilliam took a position at Exatec, a division of Sabic Innovative Plastics, as the Plasma Technology Leader, supervising global technology programs and directing international R&D teams to develop next-generation coated polymer products. As the Plasma Technology Leader, Dr. Gilliam gained experience in translating processes to industrial scale, process characterization and control, statistical design of experiments and data analysis, quantifying relationships between process parameters and product outcomes, root cause analysis, linking customer requirements to manufacturing conditions, product validation, leading cross-functional teams, and technology road-mapping.

Research Statement
The research program involves surface treatments and coatings using atmospheric plasma for a variety of applications on rigid substrates as well as micro- and nano-sized particles. Surface modification and coating is often performed to improve adhesion, tailor hydrophobic or hydrophilic properties, increase scratch and abrasion resistance, improve biocompatibility, tailor bioactivity, increase barrier properties, reduce friction, enhance resistance to chemicals, and other goals. Plasmas can be applied to modify very thin surface layers or to deposit single or multi-layer coatings without altering the bulk characteristics of materials. Atmospheric pressure plasma processes offer the versatility of plasma processes without expensive and high-maintenance vacuum equipment. Furthermore, the processes can be implemented as a continuous process without load/lock chambers for adjusting pressures.
Current research projects are targeted for applications in biomedical materials, medical diagnostics, particle dispersions, light-weight materials for transportation, UV-blocking coatings, and more. Investigation work focuses around innovative modifications of the process and apparatuses, testing various precursors, process characterization, and optimizing for performance. Experiments are designed to characterize the effects of the precursors and process parameters on the material properties and outcomes. This characterization generates process predictive models that subsequently provide the basis to tailor the properties of the coating or surface to meet the requirements.
