Christopher Rasmussen

Christopher Rasmussen's research is in the area of arithmetic algebraic geometry, especially the arithmetic of elliptic curves, abelian varieties, and associated Galois representations. He studies the absolute Galois group through its representation on geometric objects such as the canonical outer representation attached to the projective line minus three points and its natural completions. His collaboration with Akio Tamagawa (RIMS, Kyoto University) seeks to demonstrate a natural scarcity among abelian varieties whose Galois representations have constrained image. His work in computational number theory, joint with Beth Malmskog (Villanova), has determined a complete list of Picard curves over the rational numbers with good reduction away from 3. Currently, Malmskog and Rasmussen are working with several other mathematicians to bring general algorithms for the solution of S-unit equations over number fields to the open-source software platform, Sage.

Christopher Rasmussen was born in Morgantown, West Virginia, and earned his PhD at the University of Arizona in Tucson. He has held post-doctoral appointments at William Marshall Rice University in Houston, Texas and at the Research Institute for the Mathematical Sciences in Kyoto, Japan. He arrived at Wesleyan in 2008.
