PhD title: "Designing low carbon pathways for rural electrification"

Supervisors: Professor Jenny Nelson, Dr Ajay Gambhir and Dr Sheridan Few.

770 million people lack access to electricity globally. This represents both a challenge and an opportunity, with clean access to electricity enabling progress on a number of sustainable development goals. Recent falls in cost of solar photovoltaics (PV), wind power and battery storage mean that low-carbon access solutions are in many contexts the least-cost option for meeting unmet demand.

My work uses and develops models suitable for household or community scale off-grid and grid-connected systems; it also develops and applies tools that combine electricity demand modelling, energy systems modelling and geospatial data to look at country or regional pathways to universal electricity access. 

Current Research Interests:

  • Potential of Agri-PV in Sub-Saharan Africa 
  • Gaining a better understanding of national grid reiability levels in rural areas of low-income countries
  • Electricity generating infrastructure for charging light electric-vehicles in cities in Kenya and Rwanda
