Senior analytical chemist with 10 years of experience, including 3 years in a GMP environment.

Profile Summary

I am an analytical chemist with 10+ years of experience in method development, LC-MS/MS, and managing complex analytical workflows. I’ve led cross-functional teams, co-managed GMP analytical operations, and driven multiple R&D projects from early development to implementation. I enjoy building efficient laboratory processes, mentoring scientists, and working closely with stakeholders to turn technical challenges into practical solutions.
