Jennifer C. Onuora, PhD

Scientist. Consultant. Advocate.

Jennifer C. Onuora is a PhD-trained scientist, consultant, and advocate whose work sits at the intersection of global maternal and child health, data science, and social impact. She completed her doctoral degree in Nutritional Sciences at the University of Toronto's Temerty Faculty of Medicine, where she achieved a perfect GPA of 4.0/4.0 and was recognised as the most outstanding doctoral graduate by her department.

Her doctoral research generated one of the most comprehensive characterizations of early-life gut microbiome development produced from an urban low- and middle-income country. Her findings challenged prevailing assumptions about how infant gut communities develop, demonstrating that shared environmental exposures and horizontal transmission are equally important in shaping the infant gut microbiome in low and middle income settings.

Jennifer holds an MSc from Newcastle University, England, where she was awarded the prestigious Commonwealth Master's Scholarship, selected among the top 1% of international applicants globally. Prior to this, she completed her BSc in Biotechnology from Ebonyi State University, Nigeria, graduating with First Class Honours and as the Best Graduating Student. Following completion of her secondary education at Mater Misericordiae Girls' Secondary College, she graduated as the Best Student as well as the Best in Sciences. She also received the Exceptional Scholars Award for her record-breaking performance in the diocesan examinations in 2012.

Jennifer is the founder of Ellveris, a science-based platform for women that translates evidence across beauty, health, mind, and career. She is a Research and Development Scientist at Vitract, where she leads bioinformatics infrastructure and clinical trial coordination, design and analysis to generate actionable recommendations for health practitioners. She is also a Fellow at HaloHealth and a consultant through Verax Partners.
