She oversaw product development from early-stage research to prototype testing to production. During her five-year tenure at Eos, she built a track record of driving improvements in battery performance, taking out cost and increasing ease of manufacturing. She is listed as a co-inventor on three resulting patent applications.

Her previous academic research focused on chemistry and materials science. Working as a doctoral research assistant at the University of Sheffield, she developed a special class of porous crystalline materials, the structure of which can be intelligently controlled on the molecular level. The types of novel materials she helped develop may be applicable to industrial chemical production processes and gas separation/storage technology. 

Rebecca holds a doctoral degree in chemistry from the University of Sheffield (United Kingdom), master’s and bachelor’s degrees in chemistry from the same university.
