Audrey de Nazelle is a Senior Lecturer at the Centre of Environmental Policy. She is co-chair of the International Society for Environmental Epidemiology (ISEE) Policy Committee, and outgoing chair and founder of Imperial's Network of Excellence on Air Quality (NExAir).

Dr de Nazelle joined the Centre for Environmental Policy, Imperial College London, in 2012 as a lecturer in air pollution management. She is an expert in risk assessment and exposure science. Her research is at the intersection of environmental sciences, health behaviour, transportation, and urban planning. Her work aims at guiding decision makers towards health-promoting built environments and policies. It involves novel and holistic approaches to assessing behavioural, environmental and health impacts of urban plans and policies.

She conducted her postdoctoral research at the Centre for Environmental Epidemiology (CREAL) in Barcelona, Spain, where she developed and lead the European study Transportation Air Pollution and Physical ActivitieS: and Integrated Health Risk Assessment Programme of Climate Change and Urban Policies  (TAPAS). She holds a PhD and an MS from the University of North Carolina at Chapel Hill in Environmental Sciences and Engineering (UNC - ESE), where she still collaborates at the BME lab, and a Maîtrise in Mathematics from the University of Paris VI Pierre et Marie Curie.

Dr de Nazelle was named one of the "50 Most Influential Female Scholars" by SuperScholar, an organization that aims to help match prospective students to degree programmes.

Dr de Nazelle leads the London-based case study for the EU-FP7 project Physical Activity through Sustainable Transport Approaches (PASTA), for which she supervises two PhD students: Esther Anaya and Juan Pablo Orjuela

She supervises six other PhD students:  Andrea Calderon on low-carbon mobility policies in cities and their impacts on air quality and health; Catalina Cruz Piedrahita on urban agriculture and health; Rosie Riley on societal engagement for sustainable behaviours through the use of smart phones; Yue Wang on pedestrian route choice modeling using app-based data; Paul Clift on air pollution interventions in schools; and Karina Corada on greenspace and air pollution. 

Dr de Nazelle leads other studies on transport and health (SPHR2 and Imperial societal engagement seed-funded projects on rail transport proposal development) and on societal engagement (Imperial and ESRC-funded projects) through digital technology. She is also a collaborator on the EPSRC-funded project Managing Air for Green Inner Cities (MAGIC), and on MRC-funded projects on active travel (METAHIT and TIGTHAT). 

She supervises many MSc theses every year, and convenes the Pollution Management option of the CEP's MSc in Environmental Technology. She is leading an exciting new option on sustainable cities (Urban Sustainable Environments) with her colleague Tilly Collins

Dr de Nazelle leads Imperial's Network of Excellence on Air Quality (NExAIR) which aims at bringing together researchers from across Imperial to bring air quality for all. 

You can watch her present snidbits of her research at the World Economic Forum, and of her teaching at the Santa Fe Institute.
