Dr Lekan Popoola

2012 - till date. Postdoctoral Research Associate at the Centre for Atmospheric Science, Department of Chemistry at the University of Cambridge where with Professor Rod Jones. My main interest involve studying of a problem of huge significance in the form of air quality and its impact on human health. My work mainly focuses on development and deployment portable air quality sensors. In addition, I am responsible for developing detailed analysis technique for data captured as well as validating air quality models using field data.

My recent research involves deploying, managing and processing of data from a network of air quality sensor nodes at London Heathrow Airport as part of the Sensor Network for Air Quality, SNAQ Project. Part of the aims of the project were to provide source attribution within and around the airport, determine emission indices for different aircraft operation modes as well as comparing measurement data to dispersion model outputs for the airport. More recently, I am involved in a European Commission consortium (Citi-sense project) aimed at monitoring air quality in seven megacities across Europe using low-cost sensor technology. My task mainly will be to field validate the different instruments developed by the various partners within project.
