Beyond Being a Dean of Science & Vice Chancellor Emeritus, Prof. Luboobi was a Friend. Just That!

Prof. Livingstone Sserwadda Luboobi, Africa’s Icon of Mathematics is gone. The continent has lost a true giant in the field of mathematics, specifically biomathematics. This dynamic and evolving discipline, which applies mathematical principles to the study of biological systems and phenomena, has been deeply shaped by Prof. Luboobi’s legacy. At Makerere University and across Africa, his influence is etched into the fabric of research, mentorship, and innovation. Prof. Luboobi’s contributions have left lasting marks, on the hundreds, perhaps thousands, of lives he touched directly and indirectly. Each of us carries a unique memory, a lesson, or an inspiration drawn from his life and work. We will dearly miss Prof. Luboobi, a brilliant mind, a generous mentor, and a true icon of African science.

May you rest in eternal peace, Professor. Your legacy continues to inspire

To me and my peers, he was our Dean, Faculty of Science in 1995, and he read-out our names at our graduation in January 1999. Later in 2004 as Vice Chancellor, he signed off my official 4-year PhD study leave in Scandinavia. When the 4 years elapsed before I could complete, we returned to the table and successfully negotiated for extra 2 years of grace which enabled me to complete in excellence in January 2010.

Lately, after his retirement, we found ourselves closely intimate, sharing deeper thoughts on a number of social, development, strategic leadership and governance, and academic matters. As a plant biologist, spending time with a retired Professor of Mathematics, one could wonder what we would possibly have to talk about. And yet, our discussions were rich and thought-provoking. One moment that left a lasting impression on me was his quiet humility. Despite the respect and priority I extended to him, he never assumed entitlement. If he sensed I was busy, he would simply wait outside my office, whether at the Botany Building or my current Dean’s office at CONAS, without interrupting. That gesture spoke volumes.

We often talked about science, and I had much to learn from him. I asked how he had managed to start and sustain the Uganda Mathematical Society (UMS), since we were in the process of setting up the Biology Society of Uganda (BioSU) at the time. I also wanted to hear about his journey – from his undergraduate days to becoming a retired professor. As he shared his story, pausing to catch his breath after long sentences, I sensed he was deeply concerned about something. His concern was that, as of 2017, nearly all senior academics at Makerere University had begun their careers humbly as teaching assistants and risen through the ranks in various disciplines, but that opportunity had since been lost.

He believed that trying to establish a sustainable staffing system without a pool of junior staff, selected directly from the best-performing undergraduate students, was a risky path for the university’s future. With a troubled tone, he said: “I wonder how you people will manage university staffing in the long term when you have removed the foundation…” There were many lessons in that conversation for me.

In October 2023, I started assembling a grant application together with my European and American colleagues (5 Universities) for submission to National Science Foundation (NSF, USA), addressing a certain plant disease conundrum in East Africa. I realized Prof. Luboobi’s expertise in Biomathematics could be relevant. I co-opted him along with another colleague from the Department of Mathematics. I was fascinated at the express knowledge he displayed in modelling biological systems, and in our case, plant disease modelling. Much as his physical strength was less, the intellect was razor-sharp. Even though we didn’t succeed on that attempt, I had numerous other lessons to learn from his seniority.

We shared personal stories. I re-learnt that living simple as much as possible helps a lot. Although this was not new, hearing it from one you respect takes on a whole new meaning. If I died today, I wonder what my peers or junior colleagues would say about me? I would not hear it, though. I am happy I had chance to tell Prof. Luboobi what he meant to me when he was still alive.

I regret his death. We usually say it is untimely, but will death of a loved one ever be timely? Holy Scripture says, “Seeing his days are determined, the number of his months is with You; You have appointed his bounds that he cannot pass.” – Job 14:5. This is an emphasis of God’s sovereignty over life and death, highlighting that He determines the length of a person’s life and sets unchangeable limits, just as He does in setting boundaries and limits for all His creation. Prof. Luboobi could not cross the boundary set by the creator.

I am grateful that the Principal, College of Natural Sciences (CoNAS), Makerere University and his team did their best to mobilize support at the most critical moment of need. I am grateful to God for gifting Makerere University with Prof. Luboobi, and for allowing me in particular a chance to walk a little close with him in his evening days of his life between 2023-2025.

Good bye Prof. Livingstone S. Luboobi! Go and serve God with the angels. We will also join you, in the course of time! See you later when that time comes!
