Professor Phil Lightfoot
Deputy Head of School (Teaching),



Having completed a BSc in Pure Physics at Bristol University, I transferred to an MSc in Solid State Physics mainly because of an interest in advanced semiconductor devices and because of the clear route into an industrial career. Although I loved the research element of the programme, I wasn't sure that I would be satisfied working long term in the field. At the end of the course I therefore completed a PGCE at Cambridge University before returning to Bristol to take up a PhD in Polymer Physics based around developing dielectric coatings for high power semiconductor components used in high speed trains.

I’ve always tried to see the sciences as a whole rather than split into narrower and narrower branches and at the end of my PhD I applied for a research associate position within the Particle Astrophysics group at Sheffield University developing cryogenic detectors in the search for Dark Matter. I worked at Sheffield for 11 years and at ETH Zurich University (CERN) for a further year.

In 2008 because of my teaching experience I was permitted to work as a temporary lecturer at Sheffield University. I enjoyed teaching greatly and applied to join the University of York Physics Department in 2009. Between 2009 and 2017 I worked in a variety of roles including responsibility for student welfare and career development. In 2017 I became the Deputy Head of Department with a focus on the development of teaching and scholarship within the Department and University. In 2017 I became a Senior Fellow of the Higher Education Academy.  I am now a Professor at the University of York

My research expertise is in the field of particle astrophysics. My research interests are related to non-baryonic dark matter searches, neutrino astrophysics (supernova and solar neutrinos), and the development of micro-pattern avalanche devices. I am particularly interested in tasks that require cross-curricular involvement and enjoy drawing on my experience in chemistry, semiconductor physics, solid state, polymer physics, and particle physics, to assist my research.

I have expertise in the areas of micro-pattern charge readout systems and noble liquid gas detector technology. I was the first to see proportional scintillation light from a silicon photomultiplier (SiPM) and thick gas electron multiplier (THGEM) combination in single phase liquid argon. This is a key step in the development of simple large scale detectors with modular construction which could potentially form the basis of multi-tonne targets for neutrino physics or proton decay experiments, and will make large volume ‘low’ cost experiments feasible.

I have also developed new methods to improve liquid argon purity, essential for multi-tonne projects. This is being done in conjunction with a design for a novel cryogenic liquid pump for industrial applications in the LPG sector.

I led development of the world’s first mine safe heavily doped liquid scintillator containing 10% gadolinium from basic components, and successfully prepared gelled and plastic scintillators featuring 5% gadolinium with high attenuation lengths and light output. These scintillators performed on a par with traditional carcinogenic, low flashpoint alternatives, but allowed for the first time multi-tonne quantities to be considered in UK mines.

DRIFT (Directional recoil identification from tracks) is a low pressure gas filled time projection chamber experiment for directional identification of dark matter recoils. I was the first to demonstrate successful operation of Bulk Micromegas (a micropattern readout device) in a negative ion gas TPC filled with carbon disulphide. This is seen as the first step to replacing the current multi-wire grids in the DRIFT directional dark matter detectors with higher resolution mass produced micro pattern readout devices, and is a key component in the realization of large area readout gas detectors.


Although I continue to have an active involvement in particle astrophysics research, the nature of my teaching role means that I'm currently heavily involved in supporting the development of a distinctive pedagogy. This is supported through my work as Chair of the Learning and Teaching Forum which celebrates and raises the profile of learning and teaching across the University, nurturing and disseminating creativity and good practice. This is achieved through lunchtime workshops, a university magazine, a blog and an annual conference.

In 2016 the conference will explore ways in which key employability skills can be better embedded within the curriculum in order to prepare our graduates even better for the world of work.
