Dr Shenfield is a member of the Geometric Modelling and Pattern Recognition (GMPR) research group in the Communication and Computing Research Centre (CCRC) and is involved in several current research projects in the fields of image processing and interpretation and pattern recognition including:

• The Vision-based Early Warning System (VIEWS) project in collaboration with North Middlesex University Hospital looking at automatic identification of facial expressions and correlation of those to physiological states in patients at risk of deterioration.
• The Intensive Care Unit Artificial Neural Network (IcuANN) project in collaboration with North Middlesex University Hospital and the North East and North Central London Hospital Network looking at the prediction of patient response to intensive care unit admission.

Alex has successfully supervised 2 PhD students to completion in the fields of machine learning and intelligent control systems and is currently Director of Studies for a PhD student looking at developing smart grid systems for recreational vehicles.

Dr Shenfield is also actively involved in applied knowledge transfer with the Materials and Engineering Research Institute (MERI), and has recently completed successful supervision of a 2 year knowledge transfer partnership (KTP) project looking at embedding modern electronic systems design knowledge within the company partner, Thetford LTD.
