> Qualified an outsourced baseline process by root-causing defects, sources of variability, and downstream performance issues. Developing new process guidelines and refining product specs eliminated the primary defect and downstream performance issues. Worked with vendor to bring product in control and reduce product variability. Concurrently, determined legacy baseline process step had no added value, increased process turnaround time by 40% and was a source of downstream variability. > Key contributor of process baseline successor as a drop-in replacement; successor process reduced costs by several orders of magnitude. Helped mature baseline successor by refining downstream process parameters, developing understanding on defect formation and impacts on cell cycling, and refining metrology tool to improve defect detection. Translated data into metrology methods and specifications. > Multitasked to take on administrative responsibilities such as evaluating new hires and supporting HR in recruiting top talent. Innovated technician candidate selection process that improved quality of candidates selected.

> Key participant in a team effort to baseline a critical manufacturing process. Utilized experiment DOEs to determine fundamental process-structure-property relations and establish processing parameters. Company was able to scale up from a 11mm coin cell form factor to commercially-relevant form factor as a result.> Transferred mature process to production team and supported production efforts by continuously optimizing process yield, throughput, defect reduction, and process specification refinement. > Earned a leadership role as a team lab manager to author SOPs, spearhead continuous process improvement, and ensure proper resource allocation among group engineers. > Reduced engineer-technician feedback loop. Improved internal data infrastructure and systems by implementing regular technician updates.
