I joined Sussex on a national STFC research fellowship in 2007 and was appointed as Lecturer in 2008 followed by Reader in 2013 and Professor in 2017. Before Sussex I worked at the Rutherford Appleton Laboratory (2005-2007) and obtained my DPhil (PhD) from the University of Oxford.

I am co-spokesperson of the CLOUD neutrino experiment. We are constructing a 10-ton novel opaque scintillator detector 35 metres from Europe's most powerful nuclear reactor at Chooz in France. The innovation part of this project "AM-OTech" is funded by the European Innovation Council (EIC) and UKRI.

I have been heavily involved in the NOvA neutrino experiment at Fermilab for over a decade, serving as physics analysis co-coordinator from 2019-2022 and leading the muon (anti)neutrino disappearance analysis group from 2015-2019. I was elected Chair of the NOvA Institutional Board from 2016-2021.

In 2013 I was awarded the Institute of Physics HEPP Group Prize for outstanding contributions to particle physics. In 2017 I was elected as a Fellow of the Institute of Physics. From 2012-2018 I held a European Research Council (ERC) grant "AntineutrinoNOvA".

Jul/2025: our paper with results from our LiquidO "Cube" detector is out (https://arxiv.org/abs/2507.13864). This demonstrates that LiquidO technology can surpass the performance of traditional segmented detectors and that our Cube is the world's most precise LiquidO detector ever built.

Sep/2024: a warm welcome to new PhD students Max de Carlos Generowicz and Adam Wong.

Oct/2023: my Royal Society Leverhulme Trust Fellowship for 23-24 started. Many thanks to them for the research support.

Sep/2023: a warm welcome to postdoc Nicolo Tuccori who joins us to work on opaque scintillator detector technology
