Senior Lecturer
Chief Examiner
Director of CASE Research Centre


Qualifications: B.Arch(IIT); M.Ur. Dgn (HKU); PhD (HKU); AIA (SL)

Giridharan Joined University of Kent in 2012. He received his B.Arch (1994) degree from IIT Kharagpur, India. He did his M.Ur.Design (1997) and PhD (2005) degrees at the University of Hong Kong. He has both academic and professional consultancy work experience. He has held research appointments at University of Hong Kong (2006), Brunel University (2007) and Loughborough University (2009).  Prior to taking up the academic career, he had worked for organisations such as State Engineering Corporation, Urban Development Authority and Avant Garde Urban Design Partnership in Sri Lanka. In practice, he has designed personalised houses as well as large scale institutional and commercial projects. He also designed small scale interventions in towns to mega urban development projects in Sri Lanka.

His research focus is on Urban Morphology and Climatology (environmental design), with specific interest in Urban Heat Island effect and indoor overheating. He has secured large research grants from RGC (Hong Kong SAR) and EPSRC (UK), and small grants from European Union Regional Development Fund (EU), Herritage lottery fund/Kent County Council (UK) and University of Moratuwa (Sri Lanka). He has over 25 peer reviewed publications and 3 book chapters. He has also reviewed research papers for journals such as Building and Environment, Energy and Buildings, Building Research and Information, habitat International, Urban Forestry, Applied Meteorology and Climatology, Environmental Management, International Journal of Climatology, Theoretical and applied climatology, Energy for Sustainable Development and Environmental Engineering Science.
