My research is in number theory and arithmetic geometry, with an emphasis on applications to cryptography. I also work in computational number theory and am a contributor to the LMFDB and to SageMath. In my practice as a teacher, my focus is on noncoercive teaching techniques and universal design. I want my classroom to be a human, joyful space, in which all students feel welcome and cared for. Finally, I believe that the joy of mathematics is a human right, and my professional mission is to create spaces that are joyful and comfortable for all mathematicians but center people who have been historically excluded from mathematics.
