Analytical and Synthetic Chemist - Advancing Drug Discovery and Development

Profile Summary

Ph.D. Senior Scientist, synthetic and analytical chemist with a decade of experience advancing pharmaceutical R&D through expertise in both analytical and synthetic chemistry. Skilled in chromatography (HPLC, UPLC, LC-MS, GC-MS) and spectroscopy (NMR, FT-IR, UV-Vis), as well as designing and executing synthetic routes, scaling reactions, and developing novel methodologies for small molecules, peptides, and complex chemical probes. Currently embedded with the Synthetic Molecule Design and Development (SMDD) department via Eurofins PSS, where I drive analytical method development, troubleshooting, and regulatory compliance to accelerate small-molecule drug pipelines. My career spans academia, biotech startups, and industry partnerships, reflecting adaptability and a commitment to innovation. I’ve authored peer-reviewed publications, open-access lab notebooks, and technical documentation aligned with GMP standards, while mentoring teams and collaborating cross-functionally to deliver reproducible, high-quality results. Bridging science and compliance, I thrive in environments where precision, creativity, and collaboration fuel discovery.
