Research

My research seeks to change the way that emerging photovoltaic (PV) technologies are developed by using techno-economic, energy system, and PV device models to show how they behave within energy systems.  This has two main aims, to enable scientists to infer real-world performance from lab-accessible measurements, and to use exploit the differentiated properties of new PV technologies compared to commerical Silicon.  

I am also interested in the charge transport physics of disordered materials.  This includes understanding how charge transport can influence the performance of Organic Photovoltaics (e.g. through use on Monte Carlo models) or Organic LEDs and LEFETs, as well as how disordered Carbon Nanotube Networks can be trained to perform Analogue computing functions like classification.

He has published more than 50 papers, book chapters, and review articles that have been cited more than 2500 times. He is Durham lead for two EPSRC funded Centres for Doctoral Training, ReNU and ReNU+ which collectively will train more than 100 PhD students to enable an equitable transition to Net Zero.

 

Prospective Research Students

I am always happy to talk to prospective students who are interested in undertaking a PhD or MRes in areas aligned to my current interests. It would be useful when you contact me if you could let me know what kind of research you are interested in (e.g. simulation, experiment, solar cells or otherwise) as this will help ascertain whether there is a suitable, interesting research proposal.  In cases where it is not possible to progress an application (e.g. lack of relevant expertise, or mismatch in research interests) I will try to direct you to another more suitable colleague or opportunity.

Please note that if you do not have your own funding ,you will need to secure some a Scholarship before you could start.  Like most academics in the UK, I do not have my own Scholarships to award, however, applicants can apply for a Scholarship through Durham Engineering's competitive process.   This usually happens around December each year for entry to a PhD in the following October.

Teaching

Currently I teach the Analogue Electronics content in the degree at levels 1 and 2 with the aim of equipping all of our undergraduate Engineers with a working knowledge of underpinning circuit theories and how sensor and actuator systems operate.  I also supervise Level 2 Design projects, and as well several Capstone projects at BEng, MEng and MSc level, usually around the application of Solar PV in Energy Systems.
