Adrian Kelly is a lecturer in the Faculty of Engineering and Informatics and Manager of Extrusion research activities in the Polymer IRC research group at Bradford.  Adrian has a first degree in mechanical engineering and received a PhD for his research developing in-process rheological measurement techniques for polymer extrusion. He has a strong background in polymer processing (particularly extrusion and injection moulding) and process monitoring, having recently managed a large DTI funded project (CHBJ/005/00110C) to encourage the use of process metrology in the UK polymer industry.  He has an interest in thermal optimisation of polymer processing and currently holds an EPSRC grant to optimise thermal management in polymer extrusion (EP/G059330/1) in collaboration with Queens University, Belfast.

Pharmaceutical polymer engineering is one the main focuses of Adrian's current research activities, particularly twin screw extrusion of pharmaceutical formulations (solid dispersions and solutions) and the application of process monitoring techniques (PAT).  Working closely with colleagues with Pharmaceutics expertise, he is developing novel polymer-drug formulations, novel processes and novel extruded and moulded product forms.  He is also applying his knowledge of polymer melt rheology and material characterisation to pharmaceutical polymer processing. Adrian has developed a novel continuous process to manufacture co-crystals in collaboration with Professor Anant Paradkar; this has been funded through a Yorkshire Forward Proof of Concept award and is the subject of a patent application (GB0813709.3).

Adrian has experience of processing a wide variety of polymeric materials, including materials formulation research with composites, nanocomposites and additives. In addition to conventional commodity and engineering polymers, he has expertise in recycled polymers, bio-based polymers and biodegradable polymer systems.  Adrian has worked closely with a large number of companies across the polymer, additive, machinery and instrumentation sectors.

He has received research funding from EPSRC, DTI, TSB, Yorkshire Forward, METRC and WRAP, in addition to a significant amount of contract research funding from industry collaborators.  He has received 3 SPARK proof-of-concept awards, one of which was awarded a Yorkshire Forward Innovation prize. Adrian has published over 20 journal and 70 conference papers, in polymer engineering and science related fields.  He has co-authored 5 ISBN published books and reports. Recent publications include.
