Prof had a unique way of folding the curtain in his office, to catch a glimpse of what's going on around...., but alas! the curtain has symbolically fallen. He has made indelible marks in my career. I can't forget how he called me into his office about 3 days before my PhD oral exam (defense) to tutor me and boost my confidence. I was also very surprised to see him show up in person at the dedication of my son. Nigeria would have ran into trouble for lack of personnel to handle molecular diagnostics, especially at the beginning of the ongoing pandemic if not for the the number of people that have been trained with facilities made available through his unselfish efforts. He has a way of using his personal life experience, through stories, to address every situation. You instill in us to always aim for the best, especially when it comes to publishing articles. So many memories of you to share. In summary, I can say again and again that you impacted your world. Goodnight My Prof. - Dr Olukunle Oluwasemowo
