What I'm looking for

I’m looking for an R&D role where I can develop and scale high-performance personal care formulations, combine rigorous quality/regulatory work with materials-informed research, and collaborate across cross-functional teams to launch products.

I am an innovative, detail-oriented Research & Development Processing Chemist with advanced expertise in materials chemistry, formulation science, and solid-state materials research. I develop and optimize personal care products, including sunscreens, lotions, creams, lip balms, soaps, body washes, and deodorants, while ensuring adherence to regulatory standards and quality specifications.

My background includes doctoral research in solid-state chemistry on layered intermetallic materials, studying the magnetocaloric effect and investigating catalytic water-splitting conditions. I lead scale-up processes, document formulation protocols with precision, and collaborate across Quality Assurance, Manufacturing, and Product Development to deliver high-performance formulations for commercial use.
