Research : Baker works in the area of semi conductive polymers and polymer composites of polyaniline, polypyrrole, polyamic acid and polysulfone may be readily synthesised as electrochemical transducers onto screen printed electrodes. These electrodes are compatible with multi array ensembles, for the purpose of multi element analysis, which reduces the cost and time associated with evaluation and quantitative analysis. Electro-responsive polymers can be used to prepare materials that swell, shrink, or bend in response to an electric signal.

They can transform electrical energy into mechanical energy and have shown promising application in biomechanics, artificial muscle actuation, sensing, energy transduction, sound dampening, chemical separations, and controlled drug delivery, these polymers are an increasingly important class of smart materials. Since 2005- 2011 Baker has been grant holder for bilateral research grants with key partners at Bangor University, Wales (UK), Coimbra University (Portugal), State University of New York, Binghamton (USA)and Neubrandenburg University (Germany). SensorLab (UWC) and LPPI (Cergy Pontoise) have partnered in collaborative research projects (2011-2019), student training, teaching and publication in these areas of mutual research interest. The collaboration between these international laboratories draws on specialization in physical chemistry, analytical chemistry, materials science and more recently organic synthetic chemistry. The main objective remains the design and production of novel nanostructured materials for efficient electrocatalysis and energy focused applications .
