P. Roxanne (“Roxi”) Kellar, Ph.D.—former mechanical engineer and botanist-turned-educator. I create measurable STEM learning materials and edit scientific writing for clear communication and alignment between argument and evidence. I provide SME facilitation, substantive editing, and WCAG-minded QA so teams can focus on ideas, not confusion.
