Thanks for the question! I wanted to work on something that people do not understand and neutrinos and dark matter full fill that criteria.
Nowadays, the fact that neutrinos have mass, and the existence of dark matter are two of the biggest mysteries in our universe. Moreover, neutrinos might be linked to the reason why there is more matter than antimatter in the universe, another big mystery!
I wanted to work on something exciting and that required new theories, but that could also be tested in experiments. So neutrinos and dark matter fit right in!
