Imperial and MIT announce winners of first Africa-focused seed fund

Strengthening collaborations in Africa

Imperial’s Vice-President (International) Professor Maggie Dallman, said: “These exciting projects bring together teams from three continents to further our understanding in physics, infectious disease and energy. “Imperial’s excellence arises from attracting talented people and working with leading institutions from across many different regions and we are eager to grow and strengthen our collaborations with partners in Africa.” Imperial has dozens of research projects taking place across Africa.

Professor Hazel Sive, Director of the MIT-Africa initiative emphasizes the outstanding quality of MIT – Africa – Imperial collaborations. “The funded projects bring together investigators of the highest calibre. We look forward to promoting this wonderful opportunity at top universities across African countries. “MIT has set Africa as a priority region for global engagement, and such high impact joint research programs contribute to strengthening mutually beneficial connections with African colleagues.” The MIT- Africa - Imperial College London Seed Fund is one of over 20 Funds facilitated by MIT International Science and Technology Initiatives (MISTI).

Successful award winners:

Fluorescence detection of tuberculosis transmission (University of Cape Town)

The “fluorTB” consortium comprising researchers from MIT, Imperial and the University of Cape Town (UCT) in South Africa will investigate how tuberculosis (TB) is transmitted. South Africa has a high incidence of TB and researchers at UCT have developed personal clean room technology to investigate when TB is transmitted – for example, whether it spreads through actions such as talking as well as coughing – and how quickly anti-TB therapy prevents the release of infectious aerosols. The MIT - Africa - Imperial College London Seed funding will allow researchers at MIT and Imperial to explore the use of advanced fluorescence labelling – causing live bacteria to glow in a manner that will increase their visibility under a microscope.  The research could help restrict the spread of TB in the future by helping doctors to determine which patients are most infectious.

UCT’s Professor Digby Warner said: “This collaboration is very exciting as it offers the potential to speed up detection of viable TB aerosols, thereby increasing the efficacy of therapeutic interventions which can be targeted to infectious individuals in real-time.”

Principal Investigators: Dr Brian Robertson, Imperial, Professor Laura Kiessling, MIT, Professor Digby Warner, University of Cape Town.

High Energy Physics (University of the Witwatersrand)

The three teams of researchers are aiming to advance knowledge and understanding of string theory – the idea that fundamental particles are not point-like dots, but tiny strings. The study of solutions to string theory that may describe our universe has led to difficult problems that require new ideas from geometry and computation. The three teams have complementary skills and the funding will enable conferences to share knowledge and expertise. The teams hope to develop new ideas and techniques that will lead to progress on these basic questions of physics and which may also shed new light on challenging problems in mathematics and computation.

Professor Vishnu Jejjala, from the University of the Witwatersrand, said: “Working with leading experts from Imperial and MIT provides the opportunity to focus shared and complementary expertise to attack old problems with novel and innovative methodology, such as machine learning. This collaboration has the potential to better characterise the kinds of models that are natural in the landscape of theories and make contact between string theory and the real world.”

Augmented Boiling with nano-Engineered surfaces and eco-friendly Refrigerants (University of Pretoria)

Boiling of fluids, such as refrigerants or water, is a very effective way to transfer heat and is therefore employed in a wide range of applications. The three teams are aiming to improve the understanding of this important process with the ultimate aim of enhancing the boiling performance of novel refrigerants. This is a necessary pathway for unlocking the efficient use and integration of next-generation, eco-friendly fluids in renewable heating, cooling and power systems. They are particularly interested in concentrated solar-power systems and fully-passive thermally-powered cooling systems that rely on the use of low global-warming potential refrigerants. To achieve this goal, they will perform world-first experimental studies in large-scale facilities using advanced laser-based and infrared diagnostic tools as well as nano-engineering techniques to modify the properties of solid surfaces. The research could also have potential impact on water-based applications such as steam generation, steam power-plant systems and solar cooking.

Professor Josua P Meyer, from the University of Pretoria, said: “The strength of this project is that different international partners with unique expertise, experiences and experimental equipment will collaborate with each other. We will learn from each other and it will create exciting opportunities to develop follow-up projects and leverage the expertise of each partner. We are looking forward to working and publishing with Imperial College London and MIT.”
