Adam Logan
Adam Logan graduated from Princeton University in 1995 and received his doctorate from Harvard four years later. He then held postdoctoral positions at MSRI, UC Berkeley, CRM in Montreal, and the University of Waterloo as well as a tenure-track position at the University of Liverpool before leaving academia, first for finance and then to work for the Government of Canada, where he has been since 2010. His primary research interests have to do with modularity of varieties of dimension greater than 1 and arithmetic of K3 surfaces, but he is easily persuaded to work on other computational problems involving the arithmetic of geometrically interesting varieties, as illustrated by recent and ongoing work on higher modularity of elliptic curves over function fields, surfaces of maximal Picard rank, Ceresa cycles of plane quartic curves, and modular forms associated to Clifford algebras. In September 2023 he joined the Collaboration as Senior Research Associate at ICERM. From January to August 2026 he will be a visiting professor at McGill University, and in September 2026 he will return to ICERM as an organizer of the semester program “Computations on K3 surfaces and related varieties”.
Jerson Caro
Jerson Caro is a postdoctoral researcher at Boston University. His research area is Number Theory, with an emphasis on arithmetic geometry and algebraic number theory.

coordinator, at the Max Planck Institute for Mathematics in Bonn. Oana is interested in rational points on varieties (such as Shimura curves and bielliptic curves) and Mazur’s Program B.
Padmavathi Srinivasan
Padmavathi Srinivasan received her PhD in 2016 at MIT under the direction of Bjorn Poonen. She joined the collaboration in Fall 2022 after postdoctoral positions at the Georgia Institute of Technology and the University of Georgia.
