Libby is a Professor of Energy Materials at Newcastle University. Research in the Energy Materials group focuses on developing materials and devices for sustainable power, fuel and feedstocks. This includes solar cell and solar fuel devices that function at a molecular level and challenge the conventional solid-state photovoltaic technologies. It also involves extracting value from waste. Her team's research involves materials development, device assembly and characterization of the underpinning photophysics and electrochemistry. Her current roles include being the academic lead for the Northern Net Zero Accelerator PB-IAA, the  EPSRC Northeast Transient Absorption Spectroscopy & Microscopy Facility, Institution Director of the EPSRC Centre for Doctoral Training, Renewable Energy at Northeast Universities (ReNU), and she is the engagement lead for the UKRI Interdisciplinary Centre for Circular Chemical Economy and the Light Harvesting theme lead for the UK Circular Chemicals Network. She is co-Director for Post-Graduate Research in the School of Natural and Environmental Science. Libby took up a lectureship at Newcastle in September 2014 and was promoted to Reader in 2018 and Professor in 2022. Her roles have included the founding co-Director of the Centre for Energy at Newcastle and Director of the £30M Newcastle University Academic Track (NUAcT) Fellowship scheme. Previously, she was awarded a Royal Society Dorothy Hodgkin Research Fellowship and a University of Nottingham Anne McLaren Research Fellowship 2010, having spent 3 years as a post-doc at the Centre for Molecular Devices, Uppsala University, Sweden, developing dye-sensitized solar cells. She completed her PhD in 2007 at the University of York, supervised by Prof Robin Perutz FRS and Prof Anne-Kathrin Duhme-Klair.
