My PhD research investigates summertime window-opening behaviour and its role in shaping indoor heat exposure in bedrooms. Using field data collected from occupied dwellings, I analyse how occupants respond to thermal conditions and how these behaviours influence indoor environments. This work combines high-resolution environmental monitoring, including temperature, relative humidity, and COâ‚‚, with statistical and time-series modelling to characterise temperature–behaviour relationships and variability across bedrooms and households.

Alongside my doctoral research, I work as a Research Assistant on the Home Heat Health: Sleep in the City project, contributing to the analysis of indoor environmental conditions and their associations with sleep quality and thermal comfort.

My broader expertise includes natural ventilation, indoor environmental quality, overheating, thermal comfort, and building-related health outcomes, including airborne transmission of respiratory pathogens. I also have experience in computational fluid dynamics, building energy modelling, and coupled urban microclimate–building simulation approaches for assessing ventilation performance, indoor air quality, thermal comfort, and low-energy building design.

My research focuses on indoor thermal conditions, occupant behaviour, and overheating risk in residential buildings, with particular emphasis on naturally ventilated urban apartments. Since joining the ERBE Centre for Doctoral Training in October 2023, I have investigated summertime window-opening behaviour using field-based environmental monitoring and statistical modelling.

Alongside my PhD research, I work as a Research Assistant on the Home Heat Health: Sleep in the City project, where I analyse indoor environmental conditions and their relationship with sleep quality and thermal comfort in urban dwellings.

Prior to joining 91²Ö¿â, I worked as an architect, energy consultant, and researcher, specialising in building performance analysis, building physics, and energy optimisation. My previous work included sustainable building design, urban thermal comfort, natural ventilation, indoor air quality, and modelling of airborne pathogen transmission in built environments.

My technical expertise includes building energy modelling, computational fluid dynamics, statistical data analysis, artificial intelligence applications, and integrated urban microclimate–building simulation approaches. I apply these methods to evaluate thermal comfort, ventilation performance, indoor air quality, overheating risk, and low-energy building design.
