Jeremy Baumberg is a leader in nanoscience and nanotechnology, working for much of his career at the interface between academia and industry. He has led interdisciplinary nano-centres at the Universities of Cambridge and Southampton, and developed novel devices within Hitachi, IBM, his spin-offs Mesophotonics and Base4. He is widely recognised as a leading innovator in Nano, with most recent awards being the Institute of Physics Faraday Medal (2017), Royal Society Rumford Medal (2014), Institute of Physics Young Medal (2013), Royal Society Fellowship (2011) and Royal Society Mullard Prize (2005). He is interested in constructing nano-materials with unusual interactions with light, especially ones that can be fabricated on a large scale which can lead to practical use. He has developed a range of unusual nanophotonics including kilometre-scale polymer opals, and am exploring what happens when we confine light to 1nm volumes or below, for probing single molecules and reactions. He has also explored how coherent and quantum properties can be manipulated by nano-structuring semiconductors, producing unusual condensates which can work at room temperature.
