SACEMA participates in “Science in Context” programme

SACEMA PhD student, Elisha Are together with his promotor, Prof John Hargrove and SACEMA postdoc fellow, Joseph Sempa participated in the first ever “Science in Context” programme, initiated by the Faculty of Science at Stellenbosch University.The programme is designed to give first-year students exposure to contemporary issues in science that require interdisciplinary perspectives. Twenty-five students chose SACEMA’s proposed topic: “To date, we have only managed to eradicate two infectious diseases one in humans (smallpox) and one that affected livestock (rinderpest). Discuss the major barriers to eradication of an infectious disease. Which disease is likely to be the next one eradicated, and why?” This has been more shortly titled: “Eradication of infectious diseases”. The students selected Malaria, Polio, Measles and Guinea-worm disease as the most likely diseases to be eradicated. At the end of the programme students will submit an essay and give a final project presentation.

SACEMA PhD students participate in Next Einstein Forum in Rwanda

SACEMA PhD students, Eva Ujeneza and David Niyukuriparticipated in the second Next Einstein Forum (NEF) global gathering, held in Kigali, Rwanda, from 26-28 March 2018. The NEF global gathering was preceded by several pre-events that included the second African Gender Summit (14th worldwide) and the official Launch of the Rwandan Association for Women in Science and Engineering (RAWISE) for which Eva is a founding member and the Vice-President. One particular aspect of NEF is that it is a cross-disciplinary platform where around 50% of the participants areunder 42 years, and of these at least 40% are women.

The NEF 2018 was attended by 1600 delegates from Africa, Europe, Asia, and America, and it was one of the major scientific conferences in Africa. The main theme “Connecting Science to Humanity”, was addressed through different plenary sessions and side events. Amongst the highlights of the event were the launch of “Scientific African” a new open-access science journal owned by the Next Einstein Forum, and a presidential panel on “Laying the groundwork for knowledge-led economies: Policy and practice”. The panel was composed of a number of dignitaries, including President Macky Sall of Senegal, President Paul Kagame of Rwanda, Mmamoloko Kubayi-Ngubane (South Africa’s Minister of Science and Technology),Theresia Bauer (German Minister of Science, Research and the Arts, Baden-Württemberg State) and Thierry Zomahoun (CEO and President of AIMS).

The upcoming Next Einstein Forum (NEF) global gathering will be held in Nairobi in 2020, under the patronage of Kenya’s President Uhuru Kenyatta.

SACEMA PhD student attends 68th Lindau Nobel Laureates Meeting

David Niyukuri, a SACEMA PhD student was nominated by the African Academy of Sciences to attend the 68th Lindau Nobel Laureate meeting in Germany from 23–29 June 2018. This high level meeting enables cross-generational and cultural dialogue between young scientists and Nobel Laureates. David reports: “This year, the meeting was dedicated to Medicine and Physiology, and it was a great occasion to hear about great discoveries in Medicine or Physiology, Physics, and Chemistry which have led to spectacular improvement in thelives of billions of people around the world. Discussions on current health threats like antimicrobial drug resistance, the future of precision medicine and gene editing, and all the ethical questions that arise, were included in the agenda.

Besides discussions on pressing questions which need to be solved by scientists for a better future for humankind, young scientists were given an opportunity to receive advice from Nobel Laureates about their career in Science and how to do meaningful science. Young scientists were advised to be focused when applying for research positions or graduate studies, accept the pressure from their peers, and always be open to comments and criticisms. Seniors scientists and PI’s were encouraged to challenge young scientists tobe independent early in their career. The issue of impact factor, publication of negative results, Open Science and Open Access, were hot topics during a heated debate on scientific publication. Senior scientists were urged to focus, during their recruitment process for research positions, on single-paragraph narratives summarising the importance of candidates’ newest results in their respective fields. Seniors scientists agreed to take the lead in making changes in publication processes and scholarly measurement. The scientific community cannot allow the publishing process to become a surrogate for measuring scholarly value. The change of the publication process has to be driven by the scientific community. It was argued that public-funded research has to be open access; universities cannot pay twice: for publishing and for having access to articles”.

SACEMA master’s student presents at Biomath 2018

Master’s student, Khotso Matlou attended the Annual International conference on Mathematical Methods and Models in Biosciences (Biomath) which took place 24 –29 June 2018 at the Institute of Mechanics of the Bulgarian Academy of Sciences in Sofia, Bulgaria. It was part of the Year of Mathematical Biology-a joint venture of the European Mathematical Society (EMS)and the European Society for Mathematical and Theoretical Biology (ESMTB). This conference is devoted to recent research in life sciences based on applications of mathematics as well as mathematics applied to or motivated by biological studies. It is a multidisciplinary meeting forum for researchers who develop and apply mathematical and computational tools to the study of phenomena in the broad fields of biology, ecology, medicine, biotechnology, bioengineering, environmental science, etc.

The conference kicked off with the Roumen Tsanev Lecture, presented by Nevena Ilieva from the Institute of Information and Communication Technologies, Bulgarian Academy of Sciences. “It was an amazing opportunity to network with keynote speakers such as: Raluca Eftimie, Marie Doumic, Wolfgang Pauli, Miroslaw Lachowicz, Nikolaos Sfakianakis and Gail Wolkowicz”, says Khotso. The conference socials gave participants a dive into Bulgarian art, culture and history. Khotso’s presentation was entitled “Assessing risks and benefits of Indoor Residual Spraying for malaria control in Limpopo: A mathematical modelling approach”. Khotso also participated in the School for Young Scientists. The school consists of plenary lectures and sessions of an introductory nature, giving foundations and insight into the respective topic, rather than focusing on new results, and these are presented by some of the keynote speakers of the conference.

SACEMA’s director presents at meetings in the US


In February, SACEMA’s director, Prof Juliet Pulliam, attended two workshops in the United States. The first, entitled “Ecological knowledge and predictions: integrating across networks and national observatories,” brought together an international group ofresearchers who work in diverse fields within the broader discipline of ecology to discuss the state of the art of ecological forecasting. The workshop was held 19-21 February at the University of Arizona and was sponsored by the US National Science Foundation. Prof Pulliam gave a talk on epidemiological forecasting and a lightning presentation on the International Clinics on Infectious Disease Dynamics and Data (ICI3D) programme. The second workshop, entitled “Integrative approaches to understanding and predicting pathogen spill over,” focused on synthesizing data and theory to quantify the pathways that allow pathogen transmission from one species to another. The workshop was organized by researchers at Montana State University and sponsored by the Defense Advanced Research Projects Agency. Prof Pulliam presented on capacity building for epidemiological modelling. Workshop participants also worked on a number of papers that will be incorporated into an upcoming issue of Philosophical Transactions of the Royal Society, which Prof Pulliam will co-edit.
