Prof. Serwadda’s Nostalgic Student Life, Impactful Research and Joy of Mentoring Leaders
When Prof. Serwadda travelled to universities in the USA and other countries in the 1980s, he realised that students struggled to buy books in those countries. “They work in restaurants to be able to buy books and then I said oh My God, we were so privileged,” he says.
When Prof. David M. Serwadda joined Makerere University as a student pursuing a Bachelor of Medicine and Bachelor of Surgery in August of 1977, the University was offering the best to its students.
This was both in terms of the institutional environment for academia, students’ basic needs, and the general eco-environment. Halls of residence were less congested, for instance, Prof. Serwadda, who was a Livingstone resident, says he only shared a room in the first year.
Like any other student of his time, Prof. Serwadda had an account in the bookstore that would guarantee the purchase of any book that he wanted. “I would just go there, I pick this book, they deduct from my account. I would have in my bookshelf very many books,” he says. “I would be a second-year student, but buying books for third year because if you didn’t finish your account that year, when you get into the following year, you forfeit it and reset the account to zero.”
In a wide-ranging interview, Prof. Serwadda, who is retiring this year after 31 years of teaching, discusses his time at Makerere, the challenges and opportunities for the institution that is celebrating 100 years. Prof. Serwadda was in 1985 the lead author of a research paper entitled “Slim disease; a new disease in Uganda and its association with HTLV-II infection” published in The Lancet, one of the global top medical journals that first confirmed HIV/AIDS in Uganda.

A medical doctor and professor of infectious diseases at Makerere University School of Public Health, Serwadda is a co-founder of the Rakai Health Science Program (RHSP) which has in the past three decades pioneered research on the HIV/AIDS epidemic. He was the first Ugandan academic coordinator of the Masters of Public Health program at Makerere University School of Public Health. He also served as Director of Makerere Institute of Public Health from 2003 and 2007 and Dean from 2007 to 2009 when the Institute became a School.
In December 2019, he was appointed to the Board of Trustees of the World Population Council and in the same month he was elected together with 36 others among the world’s most accomplished scientists living in or focused on the developing world by The World Academy of Sciences (TWAS).
1970 and today’s generation of students, lecturers
Contrasting students and staff activism of his time, Prof. Serwadda says it was the time of President Idi Amin, the third president of Uganda from 1971 to 1979 who had crushed Makerere’s activism spirit.
Prof. Serwadda says the current generation of students have more space for activism but also opportunities to succeed because they have more freedom, liberty, and multiple platforms through which to speak out and make their demands. “You have a highly energised and a much larger population of students that can easily be organised to rally against any grievance they have,” he says.
Whereas students of his generation seemed much more obedient, students of today know their rights and are likely to talk and make staff members and management more accountable which is good if it’s not disruptive.
Students of his time were always busy. They had many job offers. He mentions for instance that during his campus days, he would never have time to idle around. From first year, Prof. Serwadda says he was on study projects working, in laboratories and wards thus many students had no time to engage in activism. For instance in my fourth year of Medical School, under Professor Charles Olweny, I was a student during the day and a research assistant throughout the night and all weekends including Christmas at Uganda Cancer Institute. “It is my perception that we were much busier than students of today and I feel that current context has made students much more demanding and engaged in more advocacy,” he says.
Regarding research and funding, Prof. Serwadda says the current generation of students and lecturers have better prospects to succeed. The internet has levelled the communication space, and created huge opportunity for global networks for research and learning. For example, if an organisation sends out a research fellowship, or scholarship opportunity, any person across the world can access the call and apply. But in the old days, only those countries with a functioning post office would receive information in a timely manner. “A new journal would come in the library and we were all booking to read them. But now, you go on the internet and download your journal,” he says.
“The world is flatter for all of us than it was. There are more funding opportunities and much easier ability to access them,” he adds.
For lecturers, as they complain about salary increments, they also need to broaden their concerns and to talk about the need for resources for research, health insurance, and expanding facilities for teaching. “They are in large part always complaining about pay, pay, we need to systematically advocate for a more comprehensive research and learning environment,” he says.
Out of the gates of Makerere, beginning of research career
After graduation in 1982, Prof. Serwadda reminisced about his internship at Nsambya Hospital after which he later joined Mulago Hospital, a National Specialised Hospital which was and still is the teaching facility of Makerere University College of Health Sciences as a Medical Officer in the Uganda Cancer Institute, UCI, in 1983. In 1985, Dr. Serwadda enrolled as a Senior Health Officer (SHO), studying a Masters of Internal Medicine at Makerere University. He would later graduate in 1989. He says he had a dead year at Makerere which he spent in the United Kingdom, the UK studying Metabolic Medicine at Newcastle Upon Tyne Medical School.
Prof Serwadda’s research in HIV/AIDS began when he was working at the Cancer Institute between 1983 to 1985. The institute was receiving patients of “Kaposi Sarcoma,” a disease which causes plaque-like lesions on the upper arms and legs and also in aggressive form involves the lymph nodes, internal organs, and mucous membranes lining the mouth, nose, and throat as often is seen with individuals with immune deficiencies, such as AIDS. This was strange then because the clinical manifestations of Kaposi Sarcoma were at the time what was being seen in the United States of America where “men were having sex with men.”
More intriguing was, according to Prof. Serwadda, as time went on, almost all patients with aggressive Kaposi sarcoma that were admitted at UCI come from Masaka and Rakai districts.
“There used to be a surgeon called Mr. J.W Carswell, who linked us to a virologist in the UK called Dr. Robert Downing and we were able to send blood samples of some patients from Uganda Cancer Institute, some of whom were residents of Masaka and Rakai districts,” he says. “The results indicated that of the 25 samples I had sent, 4 were positive for HIV, which at the time was referred to as HTLV-III,” he adds.
Though the first cases of patients with Kaposi Sarcoma had first been identified in around 1982, these were the first blood tests to confirm HIV/AIDS in Uganda. Prof. Serwadda and his colleagues knew they were on to something big, hence they travelled to Masaka and Rakai–self funded–tested more blood samples which confirmed more positive cases, and then drafted a paper for The Lancet based on results from the tests. It would take months of back and forth communication with editors, through snail-mail given that there was no internet.
The paper was published in October 1985. The paper brought visibility for Prof. Serwadda which consequently had positive and negative impacts.
There was political resistance at the time from the Obote government when stories of patients with Kaposi sarcoma signs and symptoms started emerging. When local newspaper The Start, published on December 29, 1984, the headline “Mysterious disease Kills 100 people in Rakai” Ezra Nkwasibwe, the then minister of health in Obote II government sent out a team to investigate, they concluded that this was typhoid.
On the positive side, it brought recognition to the authors. Prof. Serwadda together with co-authors wrote a big proposal that was eventually funded to establish the Rakai Health Science Program (RHSP) in 1988. “It’s like when you have built a house, and you want to build another one, it’s easy to get funding,” he said, explaining how easy it becomes for researchers to get funding once they have established a reputation.
With significant funding over the years, he says they generated an impressive number of high-impact publications in the HIV/AIDS field which has enabled Uganda and the world to understand the dynamics of transmission better. But most importantly provided HIV prevention and care to over 200,000 clients in Rakai and the greater Masaka region.
Immense research output, nurturing leaders
During his three decades at Makerere University, Prof. Serwadda says he along with colleagues has contributed immensely to research, policy, and practice. This work has underpinned some of the significant contributions to the reduction of HIV transmission and acquisition, through treatment and prevention. Prof Serwadda has on several occasions been the recipients of annual awards from Makerere School of Public Health as the most prolific publisher. he says. “We have contributed our part in uplifting Uganda and Makerere University. Makerere University is known as a place one can do excellent medical research, however, we should and must increase our effort to invest in young researchers if it is to continue to have a top ranking.”
Prof. Serwadda says seeing his former students climbing ladders in academia and leadership gives him boundless joy. “Dean Rhoda Wanyenze was my student, I supervised her Masters of Public Health, we have done a number of projects together with her, and she is now the Dean, School of Public Health,” he says. Prof. Serwadda says there is no head of the Department at School of Public Health who has not been his student at the undergraduate, post graduate level. “Now they are my bosses and I like that. That is building for the future and that’s what Makerere is all about. Seeing my students in positions of effective leadership and being able to help where I can give me enormous satisfaction.”
Before becoming an optometrist, researcher, programmer, and eye health entrepreneur, Timothy Khabusi walked barefoot to school along rough roads in Manafwa District, Eastern Uganda. For most of his primary school years, Timothy walked more than nine kilometres each day from his home to Bubulo Mixed Primary School in Manafwa District.
He would leave home at about 6:00 a.m., walk to the highway, and join other children on their way to school. On the murram road, sharp stones pressed into his feet. When the rains came, he sometimes arrived at school completely drenched. Occasionally, a truck carrying market vendors would stop and offer them a lift. “Those were few lucky days,” Timothy recalls.
At the time, however, Timothy did not see his life as unusual. It was simply how life was for many children in his village. What he did not yet know was that those long walks were helping shape a determination that would eventually take him from rural Manafwa to Makerere University and, later, the University of Edinburgh in Scotland.
Timothy Khabusi is the sixth of eight children (5 boys and 3 girls). His father, 68, a retired primary school teacher, and his mother, 60, a small retail shop owner, had limited resources but were determined to give their eight children opportunities they had not enjoyed themselves.
The family tried several ways to make ends meet. His mother ran a small local brew joint, selling malwa, a traditional fermented cereal drink. When Timothy was about ten, the family closed the malwa joint and moved on, first trying farming and later, in 2009, opening a small retail kiosk with money earned from selling a small coffee harvest.
The family kiosk changed things. Timothy started taking snacks to school and also began developing an interest in business. He sold sugarcane and later teamed up with his younger brother, Mark, to make mandazi, a popular delicacy among schoolchildren.
Behind these modest ventures were sacrifices his parents made for their children’s education and health. His father took loans to support the family through school, while both parents repeatedly emphasised the importance of education.
Timothy’s own academic journey was far from perfect.
At rural Bubulo Primary School, Timothy performed very well and earned a place at one of the best secondary schools in Eastern Uganda, Mbale Senior Secondary School, in Mbale city.
At Mbale Secondary School, he became a strong academic performer and earned a renewable merit-based bursary that covered most of his school fees. Mr Mabaku, his Mathematics teacher, taught him to connect classroom concepts to real-life problems—a way of thinking that would later shape his interest in technology and programming.
Then came a setback.
Timothy’s A-level results (15 points in Physics, Chemistry, and Mathematics) were far lower than he had expected. For someone who had always seen himself as a top student, the outcome was deeply disappointing, and he missed out on the much-coveted government scholarship. He even wondered whether university was still possible. He considered repeating his A-levels but instead applied to Makerere University on private sponsorship. He was admitted to study Optometry, although he had initially wanted to pursue Medicine and Surgery.
Then came the opportunity that changed everything.
In 2017, Timothy became a Mastercard Foundation Scholar at Makerere University, receiving support that enabled him to continue his university education. The financial uncertainty that had threatened his university education was resolved. What initially felt like failure became an opportunity that redirected him towards a field he had not planned to enter. Through optometry, he discovered a profession that linked clinical care with science, technology, research and public health.
His career journey after graduation.
After graduating from Makerere University in January 2022, Timothy set out to fulfil his ambitious mission to improve eye health in Uganda. His career began far from his village home in Manafwa: he started at a private clinic in Arua town, West Nile, hundreds of kilometres from Manafwa in Eastern Uganda. Asked why he didn’t find a job in Kampala, as most of his peers did, Timothy quickly explained that his mission is to provide the best eye health care to communities with limited access to these services.
After working for one year in Arua, he returned to Kampala. He first worked at Dr. Agarwal’s Eye Hospital from 2023 to 2025, then moved to Med-Optics, another popular eye clinic in Kampala. In February 2026, he opened his own eye clinic, Khabusi Vision Care Centre, a modern optometry centre dedicated to providing eye care services at subsidised rates to individuals and families who may face financial barriers to accessing these services.
His leadership journey
For Timothy, leadership is not about collecting titles. At Mbale Senior Secondary School, he led the Science Club, organising seminars and holiday revision programmes. At Makerere, he served as a minister at the College of Health Sciences and as a leader in the Optometry Students’ Association. Those experiences shaped a simple philosophy: leadership means seeing what needs improvement, taking responsibility, and bringing others along.
That philosophy now drives his ambitions for Khabusi Vision Care. In the coming years, he aims to strengthen the organisation’s clinical, public health, digital and research work. His longer-term vision is to build a major Ugandan eye health organisation with branches across the country, comprehensive services, research programmes and locally developed diagnostic and ophthalmic technologies.
Impact in the community
Asked about his impact in the community, Timothy quickly pointed to the number of patients whose sight he has helped restore at a modest cost they otherwise couldn’t have afforded.
“I am proud to have treated more than 10,000 patients and enabled them to see better since I began my optometry practice in 2022. Among the patients, I vividly remember a police woman who was on the verge of going completely blind due to a misdiagnosis she had received at different facilities she had visited in Kampala, until she came to Khabusi Vision Care Centre in Kyanja, where I was able to help correct the optical issue she was grappling with.” Timothy proudly states.
Timothy further enumerates the number of young people he has mentored and continues to mentor in optometry. He also offers graduate internships at his clinic and employs five young people as permanent staff. He also conducts regular community outreach activities, offering free eye check-ups in the community and subsidised treatment for those who need it.
A word to the Mastercard Foundation Scholars Community
Timothy expressed his gratitude to the Mastercard Foundation Scholars Program and Makerere University for giving him the opportunity to pursue a quality university education at a time when he had lost hope of attending university after failing to secure a government scholarship.
“I am forever grateful to Mastercard Foundation and Makerere University for giving me a scholarship that changed my whole life; without the scholarship, I would not have been able to afford the university fees; therefore, I wouldn’t have become what I am today,” Timothy points out.
Asked what advice he would give to current Mastercard Foundation Scholars, Timothy urges them to take advantage of the additional skilling and development programmes the Mastercard Foundation Scholars Program offers.
“I urge my young brothers and sisters on the Mastercard Foundation Scholars Program currently to take the capacity-building training the Mastercard Foundation Scholars Program offers; it is what will give you an advantage over others in the job market,” Timothy advises.
Looking ahead
Beyond healthcare, Timothy is a writer, programmer, and researcher. He has published “From the Slopes of Mount Elgon”, a novel about a young girl who confronts poverty and betrayal while pursuing education and dignity. Timothy’s story is not a straightforward journey from challenge to success. It is about unexpected turns: the barefoot walks, the disappointing A-level results, the unexpected scholarship, and the career he never originally intended to pursue. His advice to young people comes from that experience: one disappointing result or difficult season need not decide the rest of your life. Sometimes, you have to keep walking.
“Keep learning, keep improving, and when opportunity comes, use it—not only to change your own life, but to create opportunities for others,” Timothy advises.
Timothy is now pursuing a Master’s degree in Patient Safety and Clinical Human Factors at the University of Edinburgh. The programme has reshaped his approach to healthcare. Rather than focusing solely on individual mistakes, he examines the systems that allow failures to occur and how to redesign them to improve patient safety.
On October 5, 2026, Makerere University welcomed Mrs. Anne Twinomugisha Muhairwe, the Deputy Inspector General of Government (DIGG) and her delegation for a courtesy visit ahead of the International Ombuds Day 2026 commemoration under the theme “Ombuds: Office of Options”.
The delegation was received by Professor Barnabas Nawangwe the Vice Chancellor of Makerere University in his office where they discussed the Ombuds Day theme, the university’s successful reconciliation-based conflict resolution, ongoing infrastructure projects, and a renewed commitment to institutional partnership.
Mrs. Twinomugisha Muhairwe, who also spoke as the President of the African Ombudsman and Mediators Association (AOMA), emphasised that her office aims to be a partner in building and strengthening public institutions rather than merely a critic. Therefore, this visit marked a big step in the evolving relationship between public institutions and the Office of the Ombudsman at the Inspectorate of Government, where it is headed by Director Kakooza Savio Ntensibe, who was also part of the delegation.
The DIGG shared that the office provides essential options for resolving grievances such as administrative injustice, where people feel victimised, and unheard.
Reconciliation Underscored
While addressing the delegation, Professor Nawangwe, framed the visit as a turning point in the institution’s relationship with oversight bodies. He welcomed the DIGG, an alumna of Makerere, and commended the Ombuds methodology that prioritizes reconciliation as initiated by neutral persons or bodies to resolve disputes.
“The style of reconciliation has worked very well for us as well, ever since we started talking to the students, it has kept peace in the university,” the Vice Chancellor remarked.
“We started talking to the students and… eventually, they started to understand. Today, if you come and begin talking of strike, fellow students will tell you, ‘We came here to study’”, added the Vice Chancellor.
The engagement also discussed the practical realities of student welfare. Mrs. Twinomugisha Muhairwe, with specific interest, probed the Vice Chancellor on the status of hall renovations. In response, the Vice Chancellor explained the phased approach to renovations, noting that the university is systematically upgrading facilities to improve the living conditions.
The Vice Chancellor thereafter invited Mrs. Twinomugisha Muhairwe and her team to visit the university museum, as a gesture to underscore the spirit of the day where the Ombudsman and the university stand together.
About Ombuds Day
Ombuds Day is an international observance held annually on the second Thursday of October to raise public awareness of the ombuds profession.
According to the International Ombuds Association, an ombuds is an independent, neutral, and confidential professional who helps resolve disputes, investigate complaints, and address systemic issues within an organization, government agency, or institution.
