He received his PhD in biochemistry from the University of Nijmegen, the Netherlands. While at the State Institute for Quality Control of Agricultural Products (RIKILT) he also worked part-time at the EU Bureau Communautaire de Reference where he was involved in harmonization of laboratory testing quality management across Europe. At pharmaceutical company Organon he headed the immunochemistry and cell-based assay activities, and held responsibilities for the implementation of a Laboratory Information Management System and for outsourcing of bioanalysis work to (inter)national CROs. Through the latter contacts he made a transition to Phoenix International Life Sciences to head up the ligand-binding assay services department in Montreal, Canada where he is now living for more than 20 years. After a short stint at startup biotech Xanthus Life Sciences, in 2002 René became Chief Operating Officer of Genizon BioSciences, a genetic and pharmacogenomics research company. After Genizon he spent several years in the field of biological sample management before joining Mondial Diagnostics as Managing Director in 2016. Throughout his career René developed extensive experience in R&D management, business planning, budgeting and finance. He combines his expertise in biomarkers, laboratory assays, and quality management with a strong track record of building multidisciplinary teams with a problem-solving attitude.

Theresia Abdoel - Senior Development Specialist

Theresia is an experienced research technician specialized in the development and evaluation of diagnostics. She obtained her BASc in microbiology at the Hogeschool Eindhoven in 1998 and since then has gained extensive experience in the development of rapid diagnostics assays such as the lateral flow and latex based agglutination assays. She developed several diagnostic tests, including lateral flow assays for the detection of leptospirosis and brucellosis for human and veterinary use, and has worked on the development of a simple diagnostic tool for simultaneous diagnosis of HIV and syphilis infections in pregnant women. Theresia has extensive knowledge and experience with a variety of laboratory techniques such as ELISA, cell culture, molecular cloning, protein expression and purification, and is well versed in quality management systems and documentation (SOPs). She is also trained as an internal auditor.
