Francesca Bianchi received her PhD from the University of Oxford in 2019, under the supervision of Jennifer Balakrishnan and Alan Lauder. She is mainly interested in p-adic aspects of (computational) arithmetic geometry, in particular in p-adic heights and p-adic methods to compute rational and integral points on curves. As of 2025, she is a data scientist at SpazioDati S.r.l.
Jean Kieffer was a postdoctoral researcher at Harvard University between 2021 and 2023, focusing on computational aspects of abelian varieties and their moduli spaces. He obtained his PhD in 2021 from the University of Bordeaux under the supervision of Damien Robert and Aurel Page. Kieffer is currently a CNRS researcher in mathematics and computer science in Nancy, France, working in the Caramba research team led by Emmanuel Thomé.
Shiva Chidambaram participated in the collaboration as a research scientist at MIT. He joined in July 2021 after receiving his PhD from the University of Chicago. His main research interests are number theory and arithmetic geometry, with a focus on Galois representations, Selmer and Tate-Shafarevich groups, and computational aspects of torsion of low dimensional abelian varieties and related moduli spaces. As of 2025, he is a Van Vleck Visiting Assistant Professor, at the University of Wisconson-Madison.
Angelica Babei was a research scientist at Dartmouth College in spring 2021. Her research interests include classical and Hilbert modular forms, the arithmetic of quaternion orders and orders in semisimple algebras, and explicit methods for these arithmetic objects. As of 2025, she is an Assistant Professor at Howard University.
Andrew Booker is Professor of Pure Mathematics at the University of Bristol. He received his PhD from Princeton University in 2003 under the supervision of Peter Sarnak. His interests lie in automorphic forms and analytic number theory, including computational aspects, and he is noted for the development of algorithms for the rigorous computation of L-functions and associated data. Between 2013 and 2019, he was co-PI of the EPSRC-funded grant “LMF: L-functions and modular forms” which helped to support the LMFDB.
Jain received his doctorate in 2007 at Harvard under the direction of Noam Elkies. He spent several years at the Courant Institute of Mathematical Sciences at NYU and was a postdoctoral fellow at MSRI. He worked as a postdoctoral research scientist with the collaboration in 2020.
Betts worked in the Collaboration as a postdoc at Harvard, specialising in arithmetic and anabelian geometry, relating fundamental groups of varieties to their arithmetic properties. His thesis, completed at the University of Oxford under the supervision of Minhyong Kim, showed that classical Néron-Tate height functions on abelian varieties admit very natural descriptions in terms of fundamental groups of torsors on abelian varieties. In 2024, he joined Cornell as a tenure-track Assistant Professor.
Ben Breen received his Ph.D. at Dartmouth College in June 2020 and subsequently worked as an RTG postdoctoral scholar at Clemson University. His research interests lie in computational number theory and arithmetic geometry. His current research focuses on explicit methods for Hilbert modular forms and Cohen-Lenstra style heuristics.
Ciaran Schembri worked with the Collaboration as a research scientist at Dartmouth College. He joined in September 2019 after receiving his PhD from the University of Sheffield. His main interests are in number theory and arithmetic geometry, in particular on Shimura curves and abelian varieties with quaternionic multiplication.
Avi Kulkarni worked with the collaboration from 2020 to 2023 at Dartmouth College. His main research interests lie in arithmetic geometry and computational number theory. Before joining the collaboration, he was a postdoctoral researcher at the MPI MiS Leipzig and developer for the OSCAR computer algebra system at TU Kaiserslautern. Avi completed his PhD at Simon Fraser University in 2018.
Sam Schiavone worked with the Collaboration as a research scientist at MIT. He received his Ph.D. in 2019 from Dartmouth College. His research interests include Belyi maps, Hilbert modular varieties, and algebras of low rank.
Dr. Fabien Cléry received his Ph.D. in 2009 from the University of Lille 1. Since then, he has held positions at the University of Amsterdam, the University of Hannover, the University of Siegen, the Max Planck Institute for Mathematics in Bonn, and the University of Loughborough. His research interests are on two types of modular forms focusing on the theory but also on computational aspects. The two types of modular forms that he is currently studying are Siegel modular forms and Picard modular forms. He worked at Brown university through 2023; he took up a faculty position at Loughborough University in January 2024.
