Julie Tavernier
Maths PhD Student, University of Bath
I am a PhD student at the University of Bath, supervised by Professor Daniel Loughran. I am interested in rational points, analytic number theory and applying techniques from harmonic analysis to counting problems. I am currently working how to interpret counting results for number fields via rational points on stacks.
When not doing maths, I enjoy reading books, petting animals and playing video games.
I am one of the organisers of the Great Western Number Theory (GWNT) Seminar.
