Maria Matei

Results-driven Biochemistry Scientist with hands-on experience in protein purification,

conjugation, and analytical characterization within GMP/GDP-regulated environments. Skilled in

CAPA investigations, Quality Notifications and root cause analysis for process deviations and

material performance issues. Proficient in advanced techniques (FTIR, MALDI-TOF, XRD, DLS,

TEM, SEC, UV-Vis) and experienced in maintaining documentation under ISO 13485 and GMP

standards. Known for accuracy, collaboration, and a methodical approach to problem-solving in

diagnostic and biopharmaceutical workflows.

I am a biochemistry scientist with hands-on experience in antibody and antigen purification and conjugation within a regulated laboratory environment. I currently work at Siemens Healthineers, where my role focuses on immunoassay-related activities, including protein purification (SEC, desalting, TFF), antibody–enzyme conjugation, and analytical techniques such as SDS-PAGE, Western blot, and BCA assays.

I am trained in using ÄKTA systems and have experience working with bioprocessing equipment, method optimisation, and troubleshooting. I routinely follow SOPs, maintain accurate documentation, and work in compliance with quality and safety standards. I also collaborate closely with cross-functional teams to support manufacturing and development activities.

I hold a Bachelor’s and a Master’s degree in Biomedical Sciences, providing a strong academic foundation in biochemistry, immunology, molecular biology, and laboratory research techniques relevant to biomedical and biopharmaceutical applications.
