This is my personal webpage. Find out more below about me and my work as an experimental particle physicist at the Large Hadron Collider.
Particle Physics at CERN
I am an experimental particle physicist. Ultimately, my job is to work out why the world around us, and the universe, is the way it is. I’m currently a Royal Society University Research Fellow at the University of Sussex. The experiments I work on are the ATLAS Experiment and the FASER Experiment, both based at the Large Hadron Collider, LHC, at CERN (European Laboratory for Particle Physics) in Geneva, Switzerland.
Why particle physics?
When I was younger I always got into trouble taking things apart because I wanted to understand how they work. My research at the LHC is kind of similar - we are essentially trying to reverse-engineer the building blocks of the universe. We try to understand the universe’s smallest components, fundamental particles. What properties do they have? How do they interact with each other? How does all that give rise to the world around us? Does what we see agree with our best models of how these particles should look?! This is done by trying to recreate conditions just after the Big Bang in the laboratory.
The most exciting thing about my job is that when you’re making increasingly accurate measurements or searching for new particles, every so often you reach a point in your research where you are the first person on the planet to have ever looked at this particular thing. That’s what fundamental research is all about and that’s why I love it!
I started my PhD on ATLAS during the extremely exciting period of first collisions delivered by the LHC. Since then I have made major contributions across ATLAS in several areas: physics analysis, Monte Carlo (MC) modelling, trigger and computing. This includes significant analysis roles leading to publications from Higgs, Top, Standard Model, B-physics, Exotics and SUSY groups with world-leading precision (measurements) or limits on the existence of new physics (searches). To further broaden my experimental particle physicist expertise to include hands-on detector development in January 2019 I joined the FASER collaboration where I am currently jointly responsible for the construction and commissioning of the scintillator and calorimeter sub-detectors.
Main research interest
My primary research interest is Higgs boson and Top quark measurements on ATLAS. The discovery of the Higgs boson in 2012 is one of the major scientific achievements of this millenium. Measuring the Higgs in more detail is now a critical priority of LHC research. I have led a team of physicists in measuring Higgs boson production in association with a top quark pair (tt̄H).
Below you can find a few details about my main areas of work, my publications, my main skills, contact details and more. Enjoy!
ATLAS is one of the worlds most complex and ground-breaking scientific experiments where my main contrinbutions are data analysis and Monte Carlo simulations.
FASER is a novel experiment searching for exotic long-lived and weakly-interacting new particles at the LHC.
Outreach and Public Engagement
I enjoy communicating the work we do in particle physics and science in general with wider audiences. I also think engaging the general public in the important and broader benefit of our work is really important. Here are a few examples of my work.

Royal Society Science Book Prize
The Science Book Prize is one of the Royal Societies most high profile engagement activities. I was on the judging panel in 2022. Royal Society Page
Here is an overview of my main research activities.
I am also contributing to the longer term future of the LHC experiment programs by coordinating improvement of the next generation of event generators through the HEP Software Foundation.
I have been a member of ATLAS for more than 10 years. The ATLAS Collaboration is an international team of over 3000 scientists that oversee the ATLAS detector, one of the major detectors at the Large Hadron Collider (LHC) at CERN. It is one of the worlds most complex and ground-breaking scientific experiments.
I have played a leading role in searches for Higgs boson production in association with a top quark pair (tt̄H).
I have led measurements of rare processes that contain a top quark pair and a vector boson (tt̄V)
Effective Field Theory
I am very interested in EFT fits, of multiple regions and processes, especially in the Top quark & Higgs boson sectors.
FASER is a novel experiment searching for exotic long-lived and weakly-interacting new particles at the LHC. I have been a member of the FASER collaboration since January 2019 and am responsible for the commissioning and construction of the scintillator and calorimeter sub-detectors.
I am an author of several hundred ATLAS publications (all members of the collaboration sign all papers), two FASER publications and several publications from external collaborations.
Below are the highlights of the papers I have made major contributions to, arranged into categories. Links to the publication webpage and other information can be found on each item.
Here is a quick overview of my responsibilities, employments, education and awards.

After obtaining my Masters degree and PhD from the University of Sheffield in the UK, I have gone on to study at University College London (UCL), the European Organization for Nuclear Research (CERN), Lawrence Berkeley National Laboratory (LBNL) and am now based at the University of Sussex.
I have been entrusted with significant ATLAS-wide leadership responsibilities and have been made Analysis Coordinator (selected to oversee all members of an analysis team) for several analyses across different physics groups: Higgs, Top , SUSY and B-physics.
I have recently held two major responsibilities outside ATLAS as HEP Software Foundation (HSF) Generators WG convener and Organising Committee member of Early Career Researchers selected by ECFA to give feedback on the European Strategy Update.
After more than 10 years working on cutting edge scientific experiments I have accumulated a wide range of skills and competencies. A snapshot of the areas of expertise I have developed are shown below.
