His research career at Manchester began in 2002 and involves the application of polymer and colloid chemistry principles to solar energy and healthcare research. He has current EPSRC funding as Principal Investigator in both of these areas. It is very unusual for any academic to have such funding in two very different areas of research. This demonstrates the high international standing of our group's research in both of these diverse research areas. He has an international reputation for microgel (MG) research and published his first MG paper in 1996. MGs are pre-assembled sub-micrometre gel particles. A highlight of his healthcare research is a new method for constructing gels using pre-assembled sub-micrometer microgel particles. He has 169 peer-reviewed publications and is the corresponding author for 75% of them. Of those papers, more than 90 involve polymer colloids and more than 70 involve MGs. He also has more than 35 publications involving conjugated polymers and / or light harvesting particles for solar applications, which includes 14 perovskite solar cell (PSC) papers. We design, construct and measure the performance of our own PSCs at Manchester. Our solar group has recently achieved a published PSC efficiency of 21.28%.
