Abdulateef Gafar, Ph.D. Candidate

Abdulateef is a PhD Candidate at the Institute for Resources Environment and Sustainability (IRES). His research focuses on renewable energy systems and their socio-economic and environmental impacts, with emphasis on bioenergy systems in Sub-Saharan Africa (SSA). Abdulateef aims to develop a methodological framework for assessing and analysing the competitive potential of using biomass residues for electrification in SSA. His research utilises software such as the Open-Source Spatial Electrification Tool (ONSSET), QGIS, Python, and R to analyse data and model scenarios relevant for the selection and installation of bioenergy systems under different geographical context.

 

Gloria Mensah, Ph.D. Student

Gloria is a Ph.D. student in the Institute of Resource, Environment and Sustainability. Her research focuses on how transitions in greenhouse gas emission accounting frameworks, land-use policy downscaling, and bioeconomy biomass feedstock production strategies for bioenergy influence equitable and sustainable climate outcomes, with emphasis on distributional justice among national and subnational regions.

Gloria is a Chartered Energy Economist (Ch.EE) and a Chartered Financial Economist (Ch.FE). She holds a Bachelor’s degree in Economics from the Kwame Nkrumah University of Science and Technology (KNUST), an MSc in Economics and Development Economics from the University of Nottingham, an MSc in Business Management from the Hong Kong Baptist University (HKBU), and an MSc in Human Resource Management and Organisational Behaviour from Lingnan University, Hong Kong.


Sylvia Mensah, M.Sc. Student

I am a dedicated climate scientist with a strong academic background in environmental Science, driven by a deep passion for sustainability and evidence-based solutions to global environmental challenges.
I graduated in 2023 with a bachelor’s degree in environmental science from Kwame Nkrumah University of Science and Technology (KNUST), Ghana. During my undergraduate studies, I. conducted a research project that explored both climatic and non-climatic stressors affecting the livelihoods of smallholder farmers in the Ahafo Ano-North District. This work was published in the Journal of Regional Sustainability and contributed to broader conversations on climate vulnerability, agriculture, and food security in sub-Sahara Africa.
Following graduation, I served as a Research and Teaching Assistant in the Department of Environmental Science at KNUST. In this role, I mentored undergraduate students through their thesis projects and collaborated on multiple research studies, some of which have been submitted and published in international journals such as the Journal of Regional Environmental Change.
I am interested in the intersection of climate change with agriculture, energy access, and food systems, and how scientific insights can inform equitable and resilient policy solutions. I am eager to contribute to ongoing research, participate in leadership opportunities and expand my professional network. I look forward to immersing herself in Vancouver’s rich natural landscapes and vibrant, inclusive campus culture.
