Mavuon Ok

QC Associate

Mavuon Ok received his Bachelor of Science degree in Chemistry from the University of San Francisco, San Francisco, CA. He has over five years of combined experience working in academic/research institutions and biotech/biopharmaceutical companies.

Before he joined LCGM, Mavuon was a staff research associate in the Cancer Immunotherapy Program at the UCSF Helen Diller Family Comprehensive Cancer Center as well as the Parker Institute for Cancer Immunotherapy. Under the supervision of Dr. Fong, Mavuon was involved in 1) defining the immunological mechanisms that mediate tumor regression, 2) determining immunotherapies both in cancer patients and in pre-clinical studies, and 3) preparing libraries for human immune profiling. His last project was on the development of homegrown CAR-T qualification assays. In addition to his academic and research expertise, Mavuon has hands-on experience working in fast-paced biotech and biopharmaceutical companies using state-of-the-art instruments and equipment.

At LCGM, Mavuon is primarily responsible for supporting and testing CAR-T products ranging from cell culture, flow assay, and RT-qPCR assay. On top of the CAR-T project, he is also supporting other projects.

Julie Antonio-Sipin

QC Specialist

Julie earned her Bachelors of Science in Medical Technology degree from Lyceum Northwestern University, Philippines. Collectively, she has over 10 years in the Quality Control role with the healthcare/ biotechnology industry.  She also has 5 years of flow cytometry in a cGMP environment. Previously, she worked as a QC Analyst III for Minaris Regenerative Medicine (formerly known as: HCATS- Hitachi Chemical Advanced Therapeutic Solutions) in the Bay Area.
