Transforming Lives Fellow & Associate Professor
Summary
I am an Associate Professor of Energy -Transforming Lives Fellow at Sheffield Hallam University. I joined the Material and Engineering Research Institute in January 2024. My academic qualifications include a Bachelor of Science in Mechanical Engineering from Mekelle University (2005), a Joint Master's in Management, Engineering of Environment and Energy from UPM, EMN, and KTH (2009), and a PhD in Engineering from the University of Exeter UK (2013). I worked for over 18 years at Mekelle University in Ethiopia before joining Sheffield Hallam University. My research focuses on project management, renewable energy development, energy conservation and management, grid and off-grid energy systems, energy access, transitions, and policy.
About
I am an Associate Professor of Energy, and I joined SHU in January 2024 as a Transforming Lives Fellow. Before that, I worked at Mekelle University where I held various academic positions, including Deputy Director of Research and Development.
Prior to joining SHU, I have led and collaborated on multiple projects generating >£2.88m income to Mekelle University with a total combined projects budget value of >£8.34m. These projects were funded by UKRI, European Union, Norway Refugee Council, DAAD Germany, DfiD UK, GIZ Germany, ESRC UK, German Research Foundation, Innovate UK, KfW Germany, Tigray Regional Government, and Mekelle University. In my 18 years of academic and research experience, I have established research collaboration with more than 37 national and international universities and companies who share my research interests. The key focus of these projects include comparative analysis of off-grid and/or community energy systems in few African countries in facilitating energy access, renewable energy technology developments, understanding of the impact of energy policy in facilitating energy access, energy technologies and social interactions in the quest to facilitate energy access, curriculum and programme development in the energy sector, capacity building through funding for students at postgraduate level, energy auditing in industries to develop effective way of energy conservation and management to improve energy efficiency, off-grid energy technology developments, and other related areas. The research and collaborations continue to result in publication of high impact papers in peer-reviewed journals, including Nature Energy, Energy Policy, Energy Research & Social Sciences, Energy, Sustainability & Society, Energy Efficiency, Renewable Energy, WIREs Energy and Environment, Sustainable Energy Technologies and Assessments, and Sustainable Engineering.

Other activities
I am a fellow of the Energy Institute and serve as a mentor. I am involved in different interest groups such as a founding member of the African Institute for Sustainable Energy and Systems Analysis (AISESA) and a member of Global society of Tigrean scholars and professionals (GSTS). I regularly provided support for regional government and NGOs that include team leader for strategic energy plan for the Tigray regional government; providing professional service as a member of a Tigray power forum for the regional power sector; providing professional support for a secretariat of the Tigray infrastructure office; and developing energy policies and strategies, providing consultations for NGOs who work on vulnerable population. I regularly review manuscripts in different energy journals.
