Cornelius is the Chief Scientific Officer at Iraka Biotech. He holds a DTech (Chemistry), MSc (Life Sciences), BTech, and National Diploma (Biotechnology). He has also completed advanced courses on Clinical Vaccine Development and Biomanufacturing, Human and Veterinary Vaccinology, and Science of Quality Improvement at Oxford University. His interest in immunomodulation was triggered by the need to understand the impact of solar disinfected water (SODIS) consumption on the immunity of consumers. Resource-poor communities use Solar Disinfection (SODIS) to sterilise water before consumption because it is cost-effective, environment-and user-friendly.
