My research revolves around the integration of energy storage, electric vehicles and renewables into urban and rural city infrastructures. I also investigate carbon mitigation pathways with a focus on energy and climate impacts of emerging technologies such as decarbonised liquid fuels.

I am interested in decarbonisation pathways for existing power systems through decentralisation and electric power market reforms where individuals and communities would have greater control over their energy choices.


  • Projects on distributed renewables and energy storage, electric vehicles, and electric power markets.
  • Low-carbon electricity and transportation infrastructure planning
  • Convex optimisation; Heuristic design and optimisation.
  • Machine learning; cluster analysis; numerical models.
  • Techno-economic analysis; life-cycle assessments.


I am currently an Imperial College Research Fellow at the Grantham Institute and the Department of Physics. I was previously at University of California San Diego, where I worked on a range of different projects such as solar resource forecasting using sky imagers, grid-connected performance testing of battery modules, and power system modelling of cities and micro-grids that heavily adopt solar photovoltaics and energy storage systems. I completed my graduate studies at University of Illinois Urbana-Champaign and University of California San Diego.


  • (Internal) Imperial College students: I supervise BSc, MSc and PhD students from Physics, Electrical Engineering, and Centre for Environmental Policy on a wide range of projects ranging from electric vehicles to sustainable fuels. Please contact me to discuss opportunities.
