@petronelaletlonkane
Staff Scientist in molecular diagnostics specializing in virology and clinical laboratory workflows.
South AfricaI am a results-driven Staff Scientist with a strong academic foundation in Microbiology, Medical Microbiology (Hons) and an MSc in Medical Virology, focused on Cytomegalovirus diversity and drug resistance. Over five years I have developed advanced molecular diagnostics expertise, performing high-throughput nucleic acid extraction, PCR/RT-PCR, sequencing workflows and rigorous quality assurance in clinical laboratory settings.
I consistently streamline processes to meet urgent diagnostic demands (e.g., processing thousands of COVID-19 samples), troubleshoot complex assays, and collaborate with multidisciplinary teams to translate genomic and diagnostic data into actionable clinical results. I bring additional client-facing experience in technical sales, strong communication skills, and certified training in GLP/GCLP, sequencing, and clinical laboratory management.
