This year’s Episteme Laureate has dedicated her career to researching, innovating, and educating with an aim to providing the best care for mothers and children in Rwanda, Kenya, Sierra Leone, and her native Uganda. She has published more than 20 articles in high-impact journals focusing on reproductive, maternal, newborn, and adolescent health. Her innovative project, “The Nutrition and Wellness Hub” has assisted thousands of people in underserved communities, equipping them with up-to-date, evidence-based nutrition and wellness information, nutritional assessments, and appropriate interventions. Her vision has been to empower the community to become champions of nutrition advocacy, health promotion, nutrition education, and disease prevention.

As a midwife, Lilian has touched the lives of hundreds of women in under-resourced communities. She is also passionate about educating the next generation of midwives and nurses. Through Aga Khan University, she is an accredited continuous professional development provider and has conducted trainings that have reached thousands of nurses and midwives across Uganda. Additionally, her project “Your Nurse and Midwife on Air” aims to raise the profile of nursing in Uganda and beyond through social media, collaborations and partnerships, and training in advocacy and policy involvement.
