Dr Lizahn Haasbroek

Product Manager (Specialising in pharmacogenetics)

PhD Clinical Pharmacology (UCT), BSc Hons in Pharmacology (UP), BSc in Human Physiology (UP)

Dr Haasbroek joined the team in 2020 and brought with her essential knowledge and expertise in the role that genetics plays during drug metabolism and efficacy. Lizahn leads the development of pharmacogenomic product offerings and their significance in the clinical setting through the evaluation of various genomics technologies from microarray to Next-Generation Sequencing. Lizahn’s portfolio of experience includes management of our Ancestry testing product line; development of ISO-compliant pharmacogenomic applications for clinical trial research activities and implementation of the organisation’s first fully accredited online training programme to create awareness and understanding of the impact of genetics in Precision Medicine to both clinical professionals and academic researchers alike. As a student of knowledge herself, Lizahn looks forward to continuing to bring new insights discovered through genetic testing to further enhance product offerings and their meaning to the patient.


Paidamoyo Kachambwa

Senior Bioinformatician

PhD Candidate Human Biology (UCT), MSc Med Bioinformatics (UCT), BMedSci Hons Bioinformatics (UCT) and BSc Computer Science & Microbiology (UCT)

Paidamoyo Kachambwa interests and strengths lie in the development, management and implementation of computational processes and programs that aid in the understanding of genomic data to provide better insights into Precision Medicine. Paidamoyo’s expertise span the implementation of processes for data analysis ranging from Genome-Wide Association Studies (GWAS) in areas of oncology to applications for clinical diagnostics such as COVID-19 testing, NIPT, HLA-typing and Whole Exome or Whole Genome Sequencing (WES/WGS) for rare diseases and panels like the Hereditary Cancer Panel. Further, Paidamoyo’s domain-specific bioinformatics skills have seen her expertise being consulted to both local and international collaborators to advance their systems and processes

Part-time, she is pursuing a PhD which looks to explore factors that contribute to developing competencies in the evolving biomedical field that experiences a constant change of scope in work, largely due to continual advances and refinement in the field. Paidamoyo is outcome driven and lives the belief of supporting a holistic approach to the delivery of care, preventative and remedial, in a patient’s journey.

Dr Chris Maske is our passionate and energetic Medical Director and Consulting Pathologist, developing new products and ensuring continuous Quality Improvement through his extensive clinical genetic expertise. Dr Maske’s biomedical career spans more than two decades with both local and international experience in pathology, laboratory medicine and research.

Chris began his medical journey graduating in medicine at the University of Cape Town and completing his internship at Groote Schuur Hospital (GSH). Exploring his passion in medical research, Chris obtained an Honours degree in Medical Biochemistry at UCT followed by a PhD in Molecular Cell Biology from Oxford University, UK. Returning to Cape Town, Chris completed his Fellowship in Anatomical Pathology at UCT and GSH. Chris joined Lancet Laboratories in Johannesburg as a consulting pathologist and later headed it's Department of Molecular Pathology for eight years. Chris led a spectrum of molecular diagnostic activities and the introduction of new technologies that included somatic tumour genetics for cancer therapy, high-risk HPV-based screening for cervical cancer and, in partnership with Artisan Biomed, saw the introduction of the first non-invasive prenatal genetic screening assay within South Africa.

Chris founded QLAB Laboratories in 2017, with a focus on diagnosis, risk stratification and biomarker detection in solid tumour malignancies. He is consulting pathologist at the Breast Care Centre of Excellence at Milpark Hospital in Johannesburg and performs diagnostic and research work in the pathology and genetics of breast cancer. Chris is driven by developing and innovating technology for cost-effective and clinically effective genetic screening and diagnostic applications that will be beneficial to all patients providing them with a feeling of safety.
