Physicists observe natural phenomena – the way matter and energy interact – and create laws to explain them. They explore physical matter on every scale, from stars to sub-atomic particles, and energy in all its forms, such as light, motion and gravity. When you join us to study for a postgraduate research degree, you'll have the opportunity to make your own contribution to the pioneering work we're doing – and play a part in transforming our research into impact. Our physicists are working to advance knowledge and unlock advanced technology – and from researching new information processing and quantum computing to exploring new materials, we're using our expertise in Physics to power the future, improve industry, security, defence and the environment. In the most recent Research Excellence Framework (REF 2021), 100% of our research outputs were judged world-leading or internationally excellent, making Portsmouth the top-ranked modern university in Physics.
