Before Fran Day entertained us with talk of particles, collisions and the end of the world she sat down for a natter with our own Claudia Schaffner.

Fran Day is a PhD student in theoretical physics at the University of Oxford. She is searching for hints of new particles by looking at the light from galaxies and galaxy clusters. Fran is a science comedian, using comedy to tackle topics ranging from quantum field theory to women in science.
