Dr Helen O'Keeffe FHEA

Senior Lecturer

Research Overview

My research focuses on particle physics, in particular measuring properties of the neutrino. I collaborate with the Tokai to Kamioka (T2K), Hyper-Kamiokande and SNO+ experiments. Within these experiments, my research interests include the analysis of neutral pion production in neutrino-nucleon interactions, development of Data Acquisition methods for next-generation experiments, precision measurements of radioactive backgrounds and searches for invisible modes of nucleon decay.

In addition to my research, I organise the annual “Particle Physics Masterclass” at Lancaster, attended by approximately 180 local sixth form students.
