Biography

I joined the University of Salford in September 2010 as a Lecturer of Building Services and Performance Simulations at the School of Built Environment. The teaching responsibilities of my role are the deliveries of both undergraduate and postgraduate programmes in the subject areas of building services, physics, performance simulations, sustainable building design, as well as the broad concept of sustainability in the built environment.

Previously, from late 2001, I studied at De Montfort University for my PhD in Computational Fluid Dynamics Modelling of Displacement Natural Ventilation of Buildings, and then worked there for 5 years as Research Fellow, during the time I carried out a number of research projects, i.e.

  • Building ventilation modelling using Large Eddy Simulations.
  • Dynamic thermal simulations for the design of healthcare building in which future weather data were used to investigate their potential impacts on the current design criteria.
  • Time dependent ventilation flow modelling for a single space with a localised heat source, collaborated with Dr Nigel Kaye, from Dept. Civil Engineering, Clemson University, USA. 
  • Advanced natural ventilation modelling for a new low-energy building design in Hangzhou, south China. Both CFD and dynamic thermal simulation tools were used to conduct the investigation.
  • Evaluation of eddy viscosity turbulence models for modelling differentially heated air cavities, initiative research.
  • Numerical investigations for double skin façades and building ventilation related applications, collaboration with Loughborough University.

Teaching

Programmes/modules taught so far:

  • HND  – Building Service & Science
  • UG – Sustainable Design & Construction, BS Discipline Project 1, MDP3, MDP2, Dissertation supervision
  • PG – Low Carbon Building Design/Sustainable Building Design programme, Building Performance Simulation module, Smart Design and Performance Simulation, Sustainable Design Theory & Practice

Research Interests

My areas of research include: Natural and hybrid ventilation design and modelling, dynamic thermal modelling of buildings, and low carbon building design and consultancy, building retrofit. These areas of research feed well into the teaching practices.
