I am involved in several challenging, world-leading particle physics experiments. My field, experimental particle physics, investigates the nature of matter. The current question that most interest me is: "What is the universe made of and why?". For example, why is the Universe made out of matter? We believe the Big Bang, where all matter was created, produced an equal amounts of matter and anti-matter. However, we do not find any anti-matter in our current Universe. Where did it all go? The answer could found by studying the properties of neutrino particles. Neutrinos are fundamental particles that are very prevelant in the Universe. However, we do not experience them directly as they only interact very weakly with other forms of matter. Depending on their fundamental nature and whether they behave differently as particles and anti-particles, they could be responsible for the matter - antimatter asymmetry observed in today's Universe.

Currently, I work on two neutrino experiments to study neutrinos in order to the answer this question:

  1. SNO+ neutrino experiment in Canada, which tries to determine the nature of the neutrino.
  2. The DUNE in the USA, which tries to see if neutrinos behave differently as anti-neutrinos.

Also, most of the matter in the Universe seems to be unknown to us. We call this Dark Matter. Currently, I am working on the DarkSide dark matter experiment, which is currently being designed. I am also working on the neutrino experiment JSNS2 in Japan, which is  trying to determine whether or not there are more neutrinos than we currently have discovered.
