Working in the Additive Assembly Lab on developing advanced manufacturing techniques to fabricate smart textiles for apparel and wearable technologies.

• Designed print test platform to screen textile ink for printer reliability.• Planned, organized and managed the execution of multiple system-level tests for ink formulations. • Analyzed and communicated results of system-level testing to local and international team members, guiding ink development towards improved compatibility with thermal inkjet printing.• Created custom images for print tests in Python, elucidating mechanisms of printer-textile ink-paper interactions.• Coordinated testing with beta customers and communicated findings from initial product interaction to marketing and engineering groups.

• Led internal Army effort to develop wearable supercapacitors based on ionic liquid gel electrolytes and textile-based electrodes• Proposed and obtained funding for new research project to evaluate flexible supercapacitors for military applications• Mentored undergraduate student researcher, which resulted in future DoD scientist recruitment through the SMART (Science, Mathematics & Research for Transformation) scholarship program

• Designed coplanar supercapacitor devices based on carbon paper electrodes and ionic liquid gel electrolyte • Electrically characterized supercapacitor devices using electrical impedance spectroscopy, cyclic voltammetry, and chronopotentiometry (charge/discharge)

• Worked in a team of five to conduct Man-in-Simulant Testing of chemical protective suits to understand performance on a system level.• Led efforts to characterize chemical protective technologies in development using chemical vapor and aerosol permeation systems, adsorptive testing, and contact angle measurements.• Expanded lab capabilities for improved technology readiness level assessment of chemical protective applications leading to product transition recommendations.• Communicated project results through oral presentations to site technical director, and at program reviews hosted by the Defense Threat Reduction Agency and the Joint Program Management Office.• Presented poster on research at external conferences.
