The Centre for Radiochemistry Research (CRR) at The University of Manchester is a UK centre of excellence providing a national focus for innovative, high-impact radiochemistry research. It is a key link between academia and the nuclear sector, with activities ranging from blue skies investigations to industry-ready development work.

Our research

We are home to many different research groups, conducting a broad spectrum of world leading activities using state of the art technologies.

The CRR team

Led by co-Directors Professor Steve Liddle and Professor Nik Kaltsoyannis, we host academics from across The University of Manchester, as well as dedicated administrative and technical staff.


The CRR has an extensive network of partnerships and collaborations, both within the University of Manchester, and externally.


The CRR hosts a large number of researchers at different stages of their careers, ranging from senior postdoctoral fellows to undergraduate project students. These researchers benefit daily from the use of a wide range of facilities, gaining state-of-the-art education and training.


Louise Natarajan has been awarded £800k from the NERC for a project entitled “Optical Imaging of Uranium Biotransformations by Microorganisms (OPTIUM)”. Vanessa Timmermann, a final year PhD student in the Natrajan group, was invited to present her PhD research on ‘Evaluating the solution structure of uranium (IV) DOTA-type complexes by 1H NMR spectroscopy’ at the recent RSC NMR Discussion Group Christmas Meeting at Birkbeck College London (14th December 2017). With an aim to bring together young and eminent scientific researchers from the UK and Indian institutes towards building international connections and thereby improving the quality of their research, a Newton Bhabha Researcher Links Workshop was organized by Professor Prasun Mandal and Louise Natrajan under the aegis of the Newton-Bhabha Fund, The University of Manchester and the Indian Institute of Science Education and Research (IISER) Kolkata, India, the British Council, and the Royal Society of Chemistry, UK.

Recent work by the Liddle group published in Nat. Commun. 8 (2017) s41467-017-01363-0 has shown that uranium has the potential to execute reversible oxidative addition and reductive elimination, which are fundamental modes of reactivity normally thought to be limited to transition metals. This work conjures up all manner of possibilities, some of which are discussed in a CAMERA YouTube video. The first actinide-phosphido complexes outside of cryogenic matrix isolation have been reported by Thomas Rookes, a PhD student in the Liddle group, in Angew. Chem. Int. Ed. 56 (2017) 10495. Thomas’ work describes the synthesis of two UPU complexes prepared by different synthetic methodologies, and this hints at ways that the longstanding target of a terminal uranium-phosphido might be eventually prepared.
