Dr. Aboagye-Antwi collaborated with Dr. Frank Jiggins of the Department Genetics, University of Cambridge on the project titled “Biotic and abiotic factors influencing the costs of plasmodium falciparum infection in Anopheles gambiae s.s.”
Using a field-like set-up, his project investigated the role of An. gambiae s.s. factors and their interaction with environmental stress factors in modulating the fitness cost of P. falciparum infection in the mosquitoes; determined if patterns of survival to the infection may be attributed to mosquito factor(s) dependent expression of the trade-off between stress and immunity.
The project investigated the possible molecular mechanisms leading to the trade-off between resistance to stress and the immune response to Plasmodium falciparum infection in An. gambiae s.s. as well as the molecular architecture of how the trade-off between resistance to stress and P. falciparum infection changes with mosquito age of An. gambiae.
The fellowship provided Dr. Aboagye-Antwi with the opportunity to further explore the subject of Anopheles gambiae stress adoptive mechanisms and their impact on malaria transmission. It has also contributed immensely to knowledge towards the development of effective novel vector control tools. The use of molecular biology approaches such as ultra-sequencing, which has a wide range of applications, in addressing the topic above will further expand his skills sets and aid in the achievement of his goal of using teaching and research to help build human capacity in the developing world towards controlling tropical vector borne human diseases.
At the international level, participating in this programme has helped to facilitate north-south technology transfer that could eventually lead to poverty reduction through improved health.
Department of Biochemistry, Cell and Molecular Biology
Dr. Quaye collaborated with Drs. Caroline Trotter and Barbara Blacklaws, both of the Department of Veterinary Medicine of the University of Cambridge on the project titled “Contribution of strain diversity to rotavirus vaccine effectiveness in Ghana: Investigating human rotavirus reservoirs and strain diversity in farm animals”.
The project was aimed at determining the reservoirs of human Group A rotavirus strains in farm animals in Accra as well as investigating the molecular diversity of these animal strains.
Group A rotaviruses are the most common cause of acute gastroenteritis among children younger than five years of age. The disease burden is worse in developing than developed countries, and this observation has prompted various explanations which include the incidence of high rotavirus strain diversity in low income countries, among others. Even though the WHO has recommended a worldwide use of two licensed rotavirus vaccines, Rotarix and Rotateq, vaccine trials and post-vaccine era surveillance suggest a stark disparity of vaccine efficacy and effectiveness between developed and developing global regions. In Ghana, as with the case in many developing countries, there is close contact between humans and domestic and/or farm animals, or with the faeces of these animals. These interactions could be prime causes of zoonotic transmission and possibly genetic reassortment which could compromise the efficacy of the vaccines.
This study hypothesized that zoonotic transmission contributes to the high strain diversity in Group A rotaviruses in humans in developing countries. The study was therefore designed to determine reservoirs of human group A rotavirus strains in farm animals (e.g. pig, cow and chicken) in Accra, Ghana, and investigated the molecular diversity of these animal strains.
The 3rd Call for Applications, which was announced in August 2014, attracted a total of sixteen (16) applications out of which ten (10) UG faculty members were selected to receive Early Career Postdoctoral Research Fellowships under the programme.

Dr. Emmanuel Nyankson
Department of Materials science and Metallurgy
Dr. Emmanuel Nyankson is working with Dr. R. Vasant Kumar on a research titled “Synthesis and application of visible light photocatalyst in oil spill remediation ”.
Oil spill causes great harm to the vegetation, food crops, aquatic species and human inhabitant in the spilled zone hence different remediation strategies are employed to minimise their effect on the ecosystem. However, the current remediation strategies are toxic and expensive. To further innovate in oil spill remediation, this project proposes an innovative highly efficient oil spill remediation method using naturally abundant solar energy and environmentally benign photocatalysts. The various hydrocarbon components in crude oil can be oxidised into innocuous compounds using the concept of photocatalysis. This research will therefore involve (a) synthesizing visible light photocatalyst, (b) application of the synthesized photocatalyst in oil spill remediation and (c) conducting toxicological studies of the entire remediation process.
