Research projects

  • 2022: Partner in the research proposal “Movable Orchard Project: A Tree Focused Toolkit for Testing the Health of our Urban Vegetation” submitted for funding in the “Urban Greenspace and People Call” – RECLAIM network.
  • 2022: Principal co-Investigator in the submitted for UROP (Undergraduate Research Opportunities Programme) project “Do tree clustering arrangements affect the local microclimate? ”.
  • 2021: Principal co-Investigator in the UROP project “Studying the effect of leaf-level biochemistry and canopy-level structural traits on spectral reflectance canopy measurements”.

Dr Halios’s research addresses questions on the urban atmospheric environment related to urban forms (i.e. buildings, green infrastructure), and urban functions (i.e. urban air quality). His research has particularly focused on the experimental and modelling study of the interaction between the urban form and atmospheric flows across scales from building to neighbourhood and cities as well as indoor ventilation; the urban trees – built environment interactions and the modification of the local microclimate by clusters of trees; and of the air quality in a wide range of indoor microenvironments such as residential premises, workplaces and healthcare facilities.

His research experience has been developed during collaboration with: UK Health Security Agency (Environmental Public Health Scientist: 2021-2022), University of Reading -School of Built Environment (Postdoctoral Research Assistant in Thermal Performance of Urban Trees: 2018-2021), University of Reading – Department of Meteorology (Postdoctoral Research Assistant : 2012-2017), Physikalisch-Meteorilogisches Observatorium Davos (PMOD)-World Radiation Center (Visiting Scientist: 2011 and 2012), University of Athens (Research Assistant: 2001-2011).
