Simon earned his Bachelor of Science in Food Science and Nutrition (First Class Honours) from Karatina University, Kenya, in 2018. During his undergraduate studies, he investigated the bioactive profile and antioxidant properties of tempeh processed from a drought-tolerant lablab bean cultivar.

Simon subsequently completed a master’s degree (higher distinction) in food science and biotechnology at Kangwon National University (KNU), South Korea. His master’s research focused on evaluating the functional properties of edible plant seeds, with the aim of developing functional food ingredients with anti-obesity and anti-Alzheimer’s potential. From this study, he developed a fermented food ingredient from industrial hempseed, which demonstrated efficacy in mitigating obesity and obesity-induced Alzheimer’s disease–like symptoms in high glucose-fed Caenorhabditis elegans and a high-fat diet–induced mouse models by modulating the gut microbiota and associated metabolites.

In June 2025, Simon joined the Baker Heart and Diabetes Institute (Metabolomics laboratory) to pursue a PhD program supported by the Monash Graduate Scholarship. Simon interest is to understand lipid-mediated mechanisms in cardiometabolic diseases. His research focuses on the development and application of stable isotope lipid tracer approaches in individualised cultured cells derived from human cohort studies to elucidate the genetic regulation of lipid metabolism in cardiometabolic disorders. Findings from this research will help in identifying genetic drivers of lipid dysregulation in cardiometabolic diseases.
