The Advanced Data Science & Bioinformatics for Genomic Epidemiology Workshop was attended by over 20 fellows from various countries, who gained advanced skills in data analytics, including epidemiological modeling, phylogenetics, metagenomics, data visualization, AI, and bash scripting.
MSc & PhD scholarships
We seek motivated individuals with backgrounds in Mathematics, Statistics, Epidemiology, Biostatistics, Global Health, Data Science, Computer Science, or other related quantitative fields. In the world of research, deadlines are relentless, and competition for funding is fierce. Without strong grant writing skills, even the most innovative ideas can fall through the cracks.
The last few months have been a blast! Spring has arrived in South Africa, bringing many friends and colleagues to visit. We participated in several events, including Africa in the World, one of my all-time favourites. This event brings together politicians, business leaders, artists, journalists and scientists to advance the agenda of African excellence. Too-often, Africa is viewed as backward, poor and inefficient but this generalization is both wrong and unjust. Despite many challenges, Africa has the potential to contribute meaningfully to solving global issues. One of the highlights was sharing the stage with a good South African friend, Professor Salim Abdool Karim, who recently won the Lasker Award, which is often called “America’s Nobel Prize” for its high prestige in honouring medical scientists.
In this edition of the GEM, we highlight our opinion piece in Science on the third age of genomics, a new era poised to bring substantial global benefits. However, for this to become a reality, we need to make sure that recent investment in genomics in the Global South are maintained and expanded. This new era also requires major investments in training and capacity building in data sciences, bioinformatics and AI. In September, we hosted an advanced Data Science Workshop, selecting 20 fellows from over 2,700 applicants across Africa. We continue to expand our capacity-building programmes, recruiting multiple new MSc, PhD and postdoctoral candidates, as well as organizing additional hands-on workshops, including an upcoming laboratory-based training on library preparation in partnership with Roche.
I hope you enjoy reading this edition of the GEM as much as we enjoyed creating it. May spring in the Southern Hemisphere bring new energy and excitement for the pursuit of excellence

The first era of genomics started with the publication of Watson and Crick’s notable work on the description of the DNA double helix in 1953. This era lasted 50 years, until the publication of the human genome in April 2003. The second era is associated with the period between the completion of the human genome and the present day. I argue that, with the discontinuity caused by the COVID-19 pandemic and the spread and increased use of genomics to every corner of the world, we are entering a new, third era of genomics that provides major opportunities to advance the health of humans, animals, and the planet. However, this can only happen if the capacity that has greatly expanded in recent years is maintained and expanded further rather than left to atrophy, particularly across the global south.
The first era was mostly led by research. It involved major basic science discoveries and the development of scientific methods to first visualize, describe, and then sequence DNA. This era was characterized by small-scale
sampling and the characterization of genes, mutations and genomes of pathogens, parasites, and uni- and multicellular model organisms. As DNA sequencing technologies matured, the concept of sequencing the human genome evolved, and the Human Genome Project began. Launched in 1990, it took more than 20 years to complete and cost billions of dollars. Close to its completion, a new technology called shotgun, or short-read, sequencing emerged, allowing genomes to be sequenced more rapidly and economically. This launched the second era of genomics, often referred to as the postgenomic period, that progressed beyond the gene-centered approach of the previous era and unlocked the power of genomics to produce thousands of genomes of different organisms.
The postgenomic era also linked these data to functional studies and converted the knowledge into practical solutions, such as the identification of drug resistance mutations in microorganisms and the understanding of disease emergence, transmission, and evolution. During this era, genomic information was also used to design and
ine-tune diagnostics, therapies, and vaccines for human, animal, and plant organisms. Despite massive developments in the postgenomic era, such as “next generation” sequencing technologies, the process to develop solutions was still costly, with long turnaround times and the time from initial sequencing to the development of an intervention normally taking several years. Most were sequenced in centralized facilities, such as the Wellcome Sanger Institute, the Beijing Genomics Institute, and the BROAD Institute of MIT/Harvard.
The development of hand-held sequencers, the decrease of sequencing costs, and the use of genomics in the COVID-19 pandemic was a watershed moment to genomics and brought untold advantages. Not only did it allow the field of genomics surveillance to advance rapidly, but it also brought it to the attention of the world. For the first time in the history of genomics, whole genomes of viruses were produced within days of sampling. Originally restricted to rich countries, this capacity to sample and sequence whole virus genomes in a matter of days moved into the global south. During the COVID-19 pandemic, SARS-CoV-2 genomic data were public within minutes of being produced and could be analyzed everywhere. Highly effective genomics citizen science efforts arose, with nontraditional genomics researchers, such as high school teachers. Data production advanced to a new level, and more than 17 million genomes of SARS-CoV-2 were generated and are shared through the Global Initiative on Sharing All Influenza Data. This created a profound acceleration in sequencing. High-throughput DNA sequencers were set up in every corner of the globe, finally providing access to genomics to developing countries. In addition, the COVID-19 pandemic turbocharged the use of genomic data to develop diagnostics, therapeutics, and vaccines. Development of vaccines from a genome that formerly would take years can now be done in days or months. The discovery of COVID-19 variants in the United Kingdom, South Africa, Brazil, and India generated a series of rapid changes, some of which were very positive, such as bivalent vaccines and diagnostics that had been rapidly adapted to the new variants. This led to the belief that ambitious programs, such as the 100 Days Mission to make effective vaccines, therapeutics, and diagnostics within 100 days of identification of any pathogen, were not science fiction but a reality.
Trust between scientists, policy makers, industry, and the public will be essential to advance the new age of genomics. Impact will be measured
in terms of the interaction between public health, pharma, and discovery research to translate the results into action and products that can control an epidemic or better treat a genetic disease with precise therapies within days of its discovery. The recent characterization of Oropouche virus reemergence from the Amazon Basin allowed Brazilian health authorities to develop and implement diagnostics rapidly to detect and control outbreaks in multiple states. The same happened with Mpox in Africa, as a new clade (i.e., variant) was discovered in 2024, a health emergency was called by the World Health Organization and Africa Centres for Disease Control and Prevention, and finally, vaccines are being made available on the continent. The third era of genomics will also need to advance conservation genomics and precision breeding, particularly focused on developing resilient, higher-yield, and drought-resistant plants, crops, and animals. We need to conserve the natural environment and maintain food production with less harm to the planet so that we can survive and thrive in the time of climate change.
To allow genomics to thrive in a more unpredictable and rapidly evolving world and to achieve the ambitious objectives and unleash an era of extreme potential for genomics, decision makers and politicians have a choice to make on whether to support and expand the genomics infrastructure and expertise that were developed during the COVID-19 period. Unfortunately, this capacity is at risk of being dismantled in many global settings. If not careful, the investment in the global south can vanish in a few years as equipment gets older and is not replaced and as funding for reagents and personnel dry up. If capacity in the global south plateaus or degrades, then many of the trained scientists there may emigrate to the global north. We also need to ensure that the health benefits that can arise from these investments and efforts are truly widespread and evenly spread. The third era of genomics can provide huge opportunities if we invest and embrace it, supporting global development. Alternatively, it can increase disparities if the use of genomics turbocharges access to interventions in the global north that are unaffordable in the global south. Will the whole world see the benefit of the third area of genomics? Time will tell.

Global Collaboration
Publication in PLoS Biology, new website & tools to better classify Dengue genomes for public health response.
The new nomenclaure system is built off experience developing lineage systems for other viruses of public health importance, and is the result of a global collaboration of researchers and public health professionals.
The system aims to provide additional spatial and temporal resolution with which to discuss the large genetic diversity of dengue virus. Specifically, it splits up existing genotypes into smaller groups and provides a standardized, neutral naming system.
Broadly speaking, we define major and minor lineages within each genotype. These lineages are defined by the same rules, but use different nomenclature. In theory, minor lineages should be more useful for country-specific questions, and major lineages for regional questions. We designated an initial set of lineages based on all publicly available whole genome sequences with coverage greater than 70% in mid-2023.
We envision two ways of generating new lineage suggestions. The first is through community effort via a github repo, which is what this page is designed to help
with. Here, members of the dengue research/public health community can suggest new lineages to help with their surveillance efforts. These will be reviewed with some regularity and given a “putative” name.
The second method is an annual review, where all publicly available whole genome data is run through custom scripts to ensure that all new lineages have been identified, including appropriate putative ones suggested throughout the year. These will then be reviewed by an advisory board and assignment tools are updated.

Researchers warn that climate change is transforming Europe into a breeding ground for mosquito-borne diseases, with elongated summers, higher temperatures, and increased rainfall creating ideal conditions for mosquito populations. This year, the European Centre for Disease Prevention and Control (ECDC) reported 715 locally acquired cases of West Nile virus (WNV) across 15 European countries, exceeding last year’s figures and the 10-year average, with 51 fatalities recorded as of September 2024.
WNV can lead to West Nile fever, characterized by symptoms like fever and fatigue, and severe complications in vulnerable populations, particularly the elderly. The primary vector, the Culex pipiens mosquito, has historically inhabited Europe, but climate change has expanded its transmission capabilities into previously unaffected regions. According to Rachel Lowe, a climate and health scientist, the spread is associated with both climate shifts and increased travel following the COVID-19 pandemic.
Moreover, the Asian tiger mosquito (Aedes albopictus), responsible for transmitting dengue and chikungunya, has established itself in 13 European countries, resulting in reported cases in Italy and France this summer.
As mosquitoes proliferate in line with warmer, wetter conditions, researchers advocate for preventive
measures, such as using repellents, wearing suitable clothing, and eliminating standing water to decrease breeding sites. Additionally, there’s growing concern over asymptomatic donors possibly contaminating blood supplies with WNV.
With the rise of these diseases prompting urgent calls for surveillance and preparedness in both endemic and non-endemic areas, experts emphasize the interconnectedness of global health challenges and the need for comprehensive strategies to combat the emerging risks.
Researchers say people who live in areas where outbreaks have been reported should take precautions to avoid mosquito bites.
“We are faced with a problem where new places could become hotspots of transmission that were not prepared for this before,” says Houriiyah Tegally, a genomic epidemiologist at Stellenbosch University in South Africa.
A July preprint from Ethiopian Public Health Institute and Addis Ababa University, KRISP and CERI, on which Tegally is a co-author, found that dengue virus strains in Ethiopia closely resemble those in Italy’s 2023 outbreak. “It’s impossible to prove the directionality of this movement,” says Tegally. But this “tells us that the world is very connected, and Europe could at one point, if not already, act as a source of these arboviruses as well, because there’s local transmission”.
Stay Safe: Rising MosquitoBorne Diseases Demand Precautions
As mosquito-borne diseases increase in previously uncommon areas, researchers emphasize the importance of taking protective measures against mosquito bites. It’s recommended to use repellent, wear long-sleeved, light-coloured clothing, and install mosquito screens on windows. Reducing stagnant water in urban environments—such as in gardens, plant pots, and flower vases—can also minimize potential breeding sites. The Asian tiger mosquito, identifiable by its black-andwhite-striped legs, is a key concern.
Scientists warn of the risk posed by asymptomatic carriers who may unknowingly contaminate blood banks with diseases like WNV and Dengue Virus. Although testing mitigates this risk, it could impact the availability of blood and organ supplies; recent data showed that 190 blood donors in the U.S. tested positive for WNV this year.
These emerging risks underscore the necessity for vigilant surveillance of mosquito-borne diseases, even in non-endemic regions.

Can global health learn from FIFA’s benefit sharing model?
text:
Cheryl Baxter summary illustration: Midjourney.
Anew proposal draws inspiration from FIFA’s benefitsharing model to support fair reward systems in global health, especially in pandemic preparedness. Following the COVID-19 pandemic, global health experts recognized the critical role played by scientists, particularly those in the Global South, who identified and provided vital data about the Omicron variant. However, these scientists, like Botswana-based virologist Sikhulile Moyo and South African bioinformatics scientist Tulio de Oliveira, were the last to benefit from the treatments developed due to geopolitical constraints, even facing travel bans and threats for their contributions.
Gabriel Butin, head of global health at an international forum, spearheaded a study exploring how FIFA’s solidarity model might offer a framework for fair compensation in global health. In soccer, FIFA’s system mandates that clubs compensating players’ training clubs with solidarity payments for each transfer, providing long-term benefits to smaller clubs involved in
player development. This “solidarity mechanism” has led to substantial financial returns across players’ careers, like when Sporting CP and Manchester United received payments from Cristiano Ronaldo’s transfers.
Inspired by this model, global health advocates such as Spring Gombe suggest that a similar framework could address inequities in how health benefits and resources are distributed. A centralized clearinghouse, like FIFA’s, could track contributions from scientists worldwide and distribute resources fairly. This system could benefit the researchers and institutions contributing to pandemic data, thus sustaining research efforts in low-resource regions that often bear the brunt of epidemic responses.
The proposal is timely, as ongoing pandemic treaty negotiations with the World Health Organization (WHO) seek equitable frameworks for data sharing and benefit distribution. An approach akin to FIFA’s could streamline processes, automate benefit distribution, and establish accountability mechanisms that safeguard contributors from retaliatory actions like
travel bans. Although differences in global health governance complicate direct implementation, integrating a centralized clearinghouse and digital platform could enhance collaboration and resource sharing.
Critics, however, caution that such a model might favour wealthier nations or organizations, much like how FIFA’s structure benefits richer clubs. This risk of inequality underscores the need for flexibility and alignment with existing regulations, such as the International Health Regulations (IHR). Still, supporters argue that the pressing need for fairer pandemic preparedness systems makes FIFA’s model a valuable reference.
Ultimately, a benefit-sharing model for global health could foster international solidarity by ensuring fair rewards for pandemic data providers, fortifying research infrastructure worldwide, and building trust—elements essential for effective, equitable global health responses.

Six months can make a world of difference, especially when spent in a hub of scientific excellence. This was certainly the case for Débora Glenda Lima de LaRoque, a PhD student from the University of São Paulo (USP) in Brazil, who came to Stellenbosch University’s Centre for Epidemic Response and Innovation (CERI) to enhance her research in dengue virus phylogenetics and phylodynamics.
“My PhD project is about dengue phylogenetics and phylodynamics, and CERI has some of the biggest experts in the area,” Débora explains. “I wanted to learn how to present my findings in a way that is relevant to my field.” Her work focuses on dengue virus evolution in a small endemic area, driven by her passion for studying viruses and the local impact of dengue in her home city
As part of the fellowship, the Sigal Lab hosted Debora at the Africa Health Research Institute (AHRI). During her stay, Débora trained in virus isolation and neutralization assays to advance her research on dengue virus phylogenetics and phylodynamics. It’s always exciting to be part of these collaborations, where the exchange of knowledge and skills strengthens our ability to tackle emerging viral infections.
For anyone considering a short-term fellowship at CERI, Débora’s advice is simple: fully engage. “They have so much to teach, and the most valuable lessons come from daily interactions and meetings,” she says. As she heads back to Brazil, Débora is excited to apply her newfound skills and carry the fond memories from her time in South Africa with her.

Microbial communities, though invisible to the naked eye, shape the world in profound ways. These communities –composed of bacteria, fungi, viruses, and other microorganisms–are essential to the health of our planet and ourselves. From the air we breathe to the food we eat, microbes are involved in sustaining life, driving ecological processes, and even influencing human health. This was the backdrop against which Prof. Thulani Makhalanyane delivered his thought-provoking inaugural lecture on October 8th, 2024, at Stellenbosch University.
Marking his first year at the university, Prof. Makhalanyane’s lecture, titled “Unveiling the hidden world
within us: What environmental microbiomes can teach us about ourselves,” explored how these microbial communities are active, essential contributors to ecosystems and human health. His research focuses on how environmental changes impact the diversity and functionality of these microbes, which are critical to processes like carbon cycling, nutrient exchange, and even human digestion.
In his opening remarks, Prof. Makhalanyane offered a powerful metaphor: “The planet is a sick patient, and microbiome scientists are its healers.” This vivid image highlights the urgency of understanding and safeguarding microbial communities to heal the damage caused by human activity. His work on microbial ecosystems, particularly in the Southern Ocean, contributes
to addressing pressing global challenges, aligning with Sustainable Development Goals (SDGs) such as SDG 14—Life Below Water.
Through his research, Prof. Thulani Makhalanyane shows that microbiome scientists are indeed the healers of this planet, offering hope and solutions to some of the most critical issues facing our world today. In understanding microbes, we begin to understand ourselves and the delicate balance required to sustain life on Earth.

In the world of research, deadlines are relentless, and competition for funding is fierce. Without strong grant writing skills, even the most innovative ideas can fall through the cracks.
Writing a compelling grant proposal is an essential skill that determines whether a project will flourish or fade into obscurity. Recognizing this, researchers, scientists, and scholars gathered on the 15th of October for an insightful lecture and workshop on grant writing, hosted by Stellenbosch University’s Public Squares initiative.
This initiative, managed by Stellenbosch University’s Division for Research Development (DRD) and led by Dr. Astrid Treffry-Goatley, is designed to foster researcher capacity in collaboration, develop bold and creative ideas, and support the pursuit of competitive grant proposals. The workshop was led by Professor Tulio de Oliveira, Director of the Centre for Epidemic Response and Innovation (CERI), who has an
extensive track record in securing large-scale research grants. His message was clear: successful grant writing is not a solitary endeavor-it takes teamwork, preparation, and persistence.
Dr. Astrid Treffry-Goatley, who leads the SU Public Squares initiative, emphasized the importance of equipping researchers with these skills:
“The grant writing masterclass is a key part of our strategy to help transdisciplinary teams turn their innovative ideas into impactful, fundable projects.”
Professor de Oliveira further noted that grant writing isn’t just about securing funding; it’s about aligning research goals with funders’ priorities, learning how to communicate complex ideas effectively, and building a strong collaborative network. He stressed,
“Writing successful grants is not a one-man show. It takes teamwork.”
1. Start with a Strong Idea
A successful grant application begins with a focused, innovative research idea. “Don’t try to solve all the world’s problems in one grant,” de Oliveira advised. He emphasized the importance of a hypothesis-driven proposal with achievable aims, designed to lay the foundation for further research.
2. Align with the Funder’s Goals
To increase the chances of success, applicants must ensure their proposals align with the strategic goals of the funding body. Whether applying for national (NRF, SAMRC) or international (Wellcome Trust, EDCP) grants, understanding the specific requirements and objectives of the funder is crucial.
3. Plan and Build a Team
Grant writing takes time and collaboration. De Oliveira encouraged participants to plan months in advance, involve co-investigators early, and seek feedback from both scientific and non-scientific peers.
“Don’t submit a half-baked application—reviewers will remember your bad applications,” he warned, stressing the importance of quality over quantity.
4. Learn from Rejection
Rejection is an inevitable part of the process, but it shouldn’t discourage applicants. Instead, de Oliveira encouraged researchers to seek feedback, reassess their strategies, and enhance future applications.
5. Master the Details
Grant writing goes beyond the research plan. Supporting documents like CVs, letters of support, budgets, and data-sharing plans must be meticulously prepared. De Oliveira advised researchers to “become experts” in all aspects of the grant submission process, from formatting to budget justification.
6. Building a Diversified Funding Portfolio
In a post-pandemic world, securing multiple streams of funding has become more important than ever. De Oliveira encouraged researchers to diversify their funding sources, reducing reliance on a single grant.
Several attendees shared their reflections on the workshop and how it has enhanced their understanding of grant writing.
Amina Abdullah, a project manager from the Division of Health Systems and Public Research, reflected on her challenges with grant writing: “I have worked on a grant for a month and not submitted it. Indeed, it’s not a one-man job. I take with me that one should plan ahead. It was also amazing to have an expert willingly and freely sharing their grant sources.”
Hamond Motsi, from the Soil Science department, highlighted the importance of time management and teamwork: “To enhance grant writing skills, I learned new techniques in writing and searching for grants. It’s a team effort, and I also learned the best way to use feedback to improve.”
Liezel Smith, a senior scientist at the Division of Molecular Biology and Human Genetics , appreciated the sense of community fostered by the workshop: “It’s good to hear an expert sharing about failure and rejection; this process is daunting and can be lonely. From this lecture, I also realized that mentorship is key even in this regard.”
The Public Square workshop underscored the necessity of mastering grant writing, not just as a technical skill but as a strategic tool for career development. Whether it’s learning to navigate the complexities of funders’ requirements or building a collaborative team, researchers
left the workshop with a clearer understanding of what it takes to succeed in the competitive world of grant applications.
Grant writing is an essential skill for researchers looking to make a lasting impact, and as Professor de Oliveira aptly put it:
“Think like a reviewer—imagine you’re tired, grumpy, and hungry, and then review your application. Make it easy for them to say yes.”
“”
ful grants is not a one-man show. It takes teamwork.
