Résumé

Hi, I’m Trenton!

I’m an epidemiologist working at the intersection of maternal and child health and systems biology. My research focuses on understanding the foundations of vulnerability during pregnancy and infancy, particularly in low- and middle-income settings. 

I combine field epidemiology, clinical research, and multi-omics methods to study disease in the real-world setting, with a strong emphasis on translating biological insights into the developement of targeted therapeutics and nutritional interventions.

I completed my doctoral training at Action Against Hunger in Paris, where I led a multi-country study investigating phenotypic vulnerability in children with severe acute malnutrition. Since 2020, I have led the biomarker discovery portfolio within the Department of Food Technology, Safety, and Health at Ghent University.

I have over a decade of experience living and working across Africa and Asia.

You can find me at trenton@dailey-chwalibog.com 🥰
