**Reminiscing Professor Ogobara K. Doumbo (1956-2018)**

Professor Doumbo, a renowned scientist in Tropical Medicine and Parasitic Diseases, more specifically malaria, died on June 9th, 2018 of complications of surgery. 'Ogo', as we used to call him, was a talented, inspiring, kind and brilliant man from the famous Dogon region of Mali, West Africa. He graduated with degree in Medicine and served as surgeon in remote and poor areas of Mali. In 1992, he founded the Malaria Research and Training Center (MRCT) in Bamako (the capital city of Mali) where he built a strong network of collaborations especially with scientists from the USA and France. Ogo was a researcher 'par excellence' bestowed with several national and international awards and fellowships of prestigious academies. In May 2017, he accepted with enthusiasm our invitation to participate in this book for contributing a chapter entitled "*Malaria transmission-blocking vaccines: Present status and future perspectives*" keeping us abreast with the latest in this discipline of research. It is with an immense grief and sorrow that we learned about his demise and wish to express our deepest condolences to bereaved family and his close associates. In fond memories of this departed soul, Prof Sylvie Manguin and Dr Vas Dev dedicate this book to Professor Ogobara Doumbo for his great acumen for research and services in sharing knowledge and expertise, which would continue to inspire future generations of scientists in service to mankind.
