After completing his PhD, Fuchter moved to Australia, for postdoctoral research at CSIRO and the University of Melbourne, where he worked with Andrew Bruce Holmes. In 2007 Fuchter returned to the United Kingdom, where he began his independent academic career at the School of Pharmacy, University of London. Less than one year later he was appointed a Lecturer at Imperial College London, where he was promoted to Reader in 2015 and Professor in 2019. Fuchter is interested in how considerations of chirality can be applied to the development of novel approaches in chiral optoelectronic materials and devices. In particular, he focusses on the introduction of chiral-optical properties into optoelectronic materials. Amongst these materials, Fuchter has extensively evaluated the use of chiral small molecule additives to induce chiroptical properties into light emitting polymers for the realisation of chiral OLEDs. He has also investigated the application of such materials in circularly polarised photodetectors, which are devices that are capable of detecting circularly polarised light. As well as using chiral functional materials for light emission and detection, Fuchter has investigated the charge transport properties of enantiopure and racemic chiral functional materials. Fuchter has also developed novel molecular photoswitches – molecules that can be cleanly and reversibly interconverted between two states using light – with a focus on heteroaromatic versions of azobenzene. The arylazopyrazole switches developed by Fuchter out perform the ubiquitous azobenzene switches, demonstrating complete photoswitching in both directions and thermal half-lives of the Z isomer of up to 46 years. Fuchter continues to apply these switches to a range of photoaddressable applications from photopharmacology to energy storage. Alongside his work on functional material discovery, Fuchter works in medicinal chemistry and develops small molecule ligands that can either inhibit or stimulate the activity of disease relevant proteins. While he has worked on many drug targets, he has specialised in proteins involved in the transcriptional and epigenetic processes of disease. A particular interest has been the development of inhibitors for the histone-lysine methyltransferase enzymes in the Plasmodium parasite that causes human malaria. In 2018 one of the cancer drugs developed by Fuchter, together with Anthony Barrett, Simak Ali and Charles Coombes entered a phase 1 clinical trial, and as of 2020, it is in phase 2. The drug, which was designed using computational chemistry, inhibits the cyclin-dependent kinase 7, a transcriptional regulatory protein that also regulates the cell cycle. Certain cancers rely on CDK7, so inhibition of this enzyme has potential to have a significant impact on cancer pathogenesis.
