My role as an industrial researcher comprised scientific and engineering projects that were fundamental to advancement of technology for new products. Often this included solving problems that caused shipping delays and field failures. The duration of these projects was from several weeks to several years. For each project, I would identify experts within the company and in academia. Then I would lead the team of engineers, technicians, temporary hires, post docs, and university students. I obtained corporate funding for several students through their PhD program in the Chemical Engineering Department at Carnegie Mellon University. Larger projects required me to identify and purchase capital equipment for specialized measurements such as rheometers, ellipsometers, and spectrometers. In some cases, I designed the layout of new chemical laboratory facilities for the project.
In one recent project, I was collaborating with a colleague who is a renowned expert in finite element modeling to interpret apparently anomalous friction test results. He discovered a new and unexpected phenomenon that could account for the results, but then he left the company before the model could be validated. I attended the training classes on finite element modeling, and continued the modeling. For modeling the airflow under the cellular pocket structure of the disk polishing tape, the deformation of the the soft elastomeric pad was needed to calculate the inlet flow. I developed the elastic solid model for the polishing pad and tape assembly loaded on the spinning disk.
In a related project, I employed the multiphysics package to model and design a lab test device for reactive gas injection into the disk boundary layer during polishing. Later when I transferred to another division within the company, I learned ANSYS and rebuilt the polishing pad model for a different polishing pad geometry. The completed projects below are documented in my publications, conference presentations, and patents.
