Junior Research Fellow in Physics


I am an experimental particle physicist and member of the ATLAS collaboration at CERN. I completed my masters degree in physics at the University of Manchester. I then moved to Oxford for my DPhil in particle physics, undertaken at Wolfson College, under the supervision of Professor Todd Huffman and Professor Cigdem Issever.

Research Interests

In my research I analyse the high energy proton-proton collision data recorded by the ATLAS detector in order to search for exotic new particles or interactions, and to look for deviations from our theoretical model - the Standard Model of particle physics. If such particles or deviations were discovered this would revolutionise our understanding of the universe.

My focus is on final states containing quarks or gluons (the constituents of protons and neutrons), where each quark or gluon produces a collimated spray of particles called a jet. During my DPhil, I searched for exotic new particles which decay into two jet (dijet) final states. I now plan to use my expertise in jet physics to study the Higgs boson through its decay into dijets, in order to investigate if it behaves as predicted by our theoretical model. I will also use the Higgs boson as a tool to search for exotic new particles.
