Alexandre Lefevre is a researcher at the University of La Réunion, specializing in urban climate, urban heat, and climate adaptation in tropical island environments. His research focuses on urban overheating, urban heat island effects, outdoor thermal comfort, and the interactions between urban morphology, land use, and local climate. He combines field measurements, sensor networks, spatial analysis, and microclimate modelling to assess heat exposure and identify climate-responsive urban planning strategies. His work aims to support the development of more resilient and thermally comfortable cities, with particular emphasis on the specific environmental and planning challenges faced by small tropical islands under climate change.
