I am a PhD student under the supervision of Jan-Hendrik Evertse and Peter Stevenhagen. I am interested in number theory and surrounding areas, in particular the distribution of class groups and Diophantine equations in positive characteristic. Together with Carlo Pagano I am organizing a seminar on the work of Alexander Smith, see here.
