About Sepideh

A scientist,
then a leader.

Sepideh began her career on the bench — performing QC release and stability testing for biologic products using HPLC, CE, LC/MS, ELISA, PCR, LAL, and sterility assays. Over two decades, she progressed through Senior Associate, QA Technical Manager, Senior Supervisor, Director, and Senior Director roles across Biogen, Genentech/Roche, Bachem Americas, and BioDuro.

At BioDuro she directed Quality Control operations supporting 35+ client programs across biologics and peptide therapeutics, built a high-performing QC organization of 20+ scientists and 4 managers, and hosted client and QP audits supporting commercial readiness. At Genentech she led technology transfer of a Phase III biologic assay and contributed to successful FDA inspection outcomes.

In 2023 she launched Mahcom Consulting Services to bring that depth — bench-up, leadership-tested, inspection-proven — directly to clinical-stage and commercial biopharmaceutical clients worldwide.
