 I bring greetings from Kenya. It's really a great honor for me to have received this invitation to chair this session by MSF, which is an amazing organization reaching out to areas where other people don't go. I really appreciate the things I've listened to this morning from your directors about the value of implementation science and its place in improving the work that we do, constantly questioning how we do it, questioning our processes, and seeing how we can improve them. I think that we all know medicine is full of wonderful interventions, which are in dustbins, literally, and have never been implemented or well-intended programs that never took off and never achieved the goals they were set out to do. So when I went through the program this morning, and I looked at the diversity and the work done by various people from MSF who will be presenting this morning on various projects from TB self-testing, which is a pet project now for pre-exposure prophylaxis. Thank you for having those presentations. Maternal child health care, palliative care, and keeping in mind what we had from your director, but always keeping in focus the people that we serve and being clear on the goals of what we do.
