Dr Marcella Ucci is Associate Professor in Environmental and Healthy Buildings at the Bartlett's UCL Institute for Environmental Design and Engineering, University College London (UK). 

She graduated in architecture from the University of Naples (Italy), and then obtained an MSc in Environmental Design and Engineering, and a PhD in indoor air quality and modelling – both from the Bartlett School of Graduate Studies, UCL. 

Her research focuses on the interactions and tensions between sustainable building design/operation and the needs of occupants in terms of comfort, health and wellbeing. Her expertise includes building performance monitoring and modelling, evaluation of indoor air quality (especially biological such as dust mites), active design, and operational aspect of buildings - especially occupant behaviour.

Dr Ucci is Secretary (Chair between 2012-2017) of the UK Indoor Environments Group (UKIEG) - a multidisciplinary network of academics, policy-makers and industry - set up to co-ordinate and provide a focus for UK activity concerned with indoor environments, health and well-being. She was also a Committee member of the Sustainability Special Interest Group at the British Institute of Facilities Management (BIFM) between 2010 and 2016.
