Senior Global Health Consultant | Researcher | AI Student I work to find better ways to deliver high-quality life-saving health services to people in the most remote and complex settings. For over 20 years, I have worked on developing and implementing community health and malaria control programs across Africa and Asia. My work spans research, technical advising, program leadership, and health systems strengthening in resource-constrained and crisis-affected settings. I'm currently focused on studying AI and how AI tools can be applied to improve global health. As I learn, I'm sharing educational content on AI & GH, building AI tools, building community, advising global health organizations on integrating AI tools into their work, and supporting AI capacity building efforts.
