Most of my research aims at improving our understanding of the environmental impact from information and communication technologies (ICT) and the reduction of such impact.

My most significant research contributions, so far, have been in the area of the quantifying the direct impact of ICT. I have a deep understanding of the principles that affect energy consumption in Internet-based services. Based on this, my research has pioneered new methods and tools to assess the carbon footprint of digital media which have been applied by major international media companies. I am currently leading the technical development of the DIMPACT tool (http://www.dimpact.org).

A growing area of my research focusses on the complex system of interactions between use of ICT services, use of infrastructure and design of ICT services, and in response I apply multidisciplinary methods from software engineering, human computer interaction and environmental science. 

I also develop infrastructure for sensing of urban environments, in and outside buildings, focussing mainly on energy consumption and air quality.

In my teaching, a positive student learning experience is a top priority for me. I draw from my professional experience to create an authentic learning environment that is motivating and effective in preparing our students for their future careers. 

In our software engineering unit (https://bristol.ac.uk/software-engineering) students build prototypes for a wide set of “clients”, including local not-for-profit organisations from Bristol, all the way to international corporations; and is inviting new project proposals.
