Research and expertise

My research mainly focuses on advanced daylight simulation and measurement. My PhD thesis investigated the applicability of Climate-Based Daylight Modelling (CBDM), looking at the more widely adopted simulation methods to evaluate annual daylight performance using locale-specific weather data. My doctoral research covered: a survey of the uptake of CBDM among academics and practitioners; a benchmarking evaluation of CBDM metrics used in energy certification schemes and in design guidelines; and a comparison between simulated and measured daylight levels, using a database of High Dynamic Range (HDR) images collected in a live school building. 

At the moment I am assessing the solar radiation models that are used to derive irradiance and illuminance values in weather files for building performance simulation. I source data from existing large databases of weather variables (Met Office, Public Health England, NOAA ISD, etc) and I test the effect of varying solar radiation models on typical building performance analyses, such as overheating and daylighting.

I heavily rely on python for data analysis (e.g. Pandas for time series analysis, Matplotlib and Scipy for regression analysis, SALib for Sensitivity Analysis) and on command-line Radiance to run daylight simulations (2-, 3-, and 5-phase methods).

My research interests also include digital image processing, art conservation, data visualisation, indoor environmental quality and model calibration techniques.

I contribute to learning and teaching activities across the Schools programmes including:


  • Advanced Design Skills (2ndYear BArch)


  • Supervision of research projects aligned to my research interests


Short courses 

  • Designed and delivered the practical part of a CPD course on Climate-Based Daylight Modelling



I graduated from Politecnico di Milano, Italy, in 2013 with a Master’s Degree in Building Engineering and Architecture. I then started my doctoral degree in the School of Architecture, Building and Civil Engineering at Loughborough University, and was awarded a PhD in 2018 for my research on the ‘Applicability of Climate-Based Daylight Modelling’. My doctoral studies were funded by an EPSRC CASE Award in collaboration with Arup UK, a world-leading engineering consultancy company where I spent some time as an intern. I presented my PhD research at numerous conferences and workshops, like the International Radiance Workshop 2016 in Padua, Italy, or the IBPSA 2017 Building Simulation conference in San Francisco, USA. The main findings from the work resulted in three first-authored journal publication, as well as a number of awards at national and international level.

The Post-Doc project I am currently working on builds on my PhD research and investigates the role of solar radiation models in Climate-Based Daylight Modelling and in other building performance simulation realms, such as overheating analysis. The project is funded by the Chartered Institution of Building Services Engineers (CIBSE) and will feed into the future releases of the official CIBSE weather files for building performance simulation.
