Freelance Regulatory Affairs Specialist for Drugs, and Medical Devices/Regulatory Writer, Drug Developer

Profile Summary

Bridging the gap between complex chemical problem-solving and strategic regulatory navigation, I contribute to the development of innovative pharmaceuticals that meet the highest standards of safety and efficacy. With a strong foundation in organic chemistry and a nuanced understanding of drugs, biologics and medical devices regulations, I play a pivotal role in guiding drug substances from early-stage synthesis through to commercialization and regulatory approval.
