 I'm Lois Epoa Ochoa-Dante from Ghana, West Africa. I'm a second year PhD student at the Open University in the School of Engineering and Innovation, and I'm funded by the Global Challenges Research Fund. So my research project focuses on modifying the surfaces of materials to be able to absorb and degrade chemical organic compounds that are present in water bodies that you cannot see with your eyes using the power of the sun. So these materials are low-cost and environmentally friendly and they are able to absorb the highest part of the sun, which is the visible light. The long-term impact of the work is creating solar-powered water filtration systems for all mainly looking at developing countries using Ghana as a case study. Each year, millions of children under the ages of five die out of water-bond-related diseases, such as cholera and dysentery. And I've had my first kind of experience of lack of accessibility to clean water. So I think the main impact of this work is trying to save a life and save children who are future leaders in the long run. I think researching in the OU has been a very awesome experience. I've had the opportunity to be able to meet new people and also be able to learn new things. I've also had the freedom to be able to use state-of-the-art technology and its equipment and easy accessibility to leading academics to be able to help to direct your research focus. And most of the events that are organized as well has helped build me professionally and academically. I would like to use this opportunity to thank my supervisor, Professor Satish Krishnamathi and our interdisciplinary group that are helping to address global challenges in partnership with industries of the Open University and also creating that fun-loving and relaxing environment to make research in the Open University feel like home.
