I am a research associate at Dartmouth College, working with John Voight as part of the Simons Collaboration on arithmetic geometry, number theory and computation. My current research is centred on Shimura curves with level structure and torsion of abelian surfaces over the rationals which acquire endomorphisms by a quaternion algebra over some extension.
