Oana Padurariu

Oana Padurariu is a fifth-year graduate student at Boston University working with Jennifer Balakrishnan. She will be graduating in Spring 2023. 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 will join the collaboration in Fall 2022 after postdoctoral positions at the Georgia Institute of Technology and the University of Georgia. She is interested in various explicit aspects of families of curves and abelian varieties, and their applications to the study of rational points on curves.

Barinder Banwait

Barinder Banwait will be joining the Collaboration in September 2022 as a Postdoctoral Associate at Boston University. His research into rational points on modular curves includes work on computing pseudoeigenvalues of modular forms as well as determining uniform sets of prime-degree isogenies of elliptic curves. He is also interested in computational aspects of Galois representations of higher dimensional abelian varieties and has contributed to Sage and the LMFDB. Barinder received a BA and MMath from Cambridge University in 2009 and a PhD from Warwick University in 2013 under the supervision of John Cremona. After postdoctoral positions in Bordeaux, Essen and Prayagraj, as well as industry positions in Cambridge and London in the Surgical Robotics and Quantitative Finance sectors, he is currently a postdoctoral researcher in the Computational Arithmetic Geometry group at Ruprecht-Karls-Universität Heidelberg.

Francesca Bianchi

Francesca Bianchi is a postdoc at the University of Groningen. She 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.

Jean Kieffer

Jean Kieffer is a postdoctoral researcher at Harvard University, focusing on computational aspects of abelian varieties and their moduli spaces. After studying at ENS in Paris, Kieffer recieved his PhD in 2021 from the University of Bordeaux for his work on explicit isogeny computations and point-counting algorithms for abelian surfaces.

Shiva Chidambaram

Shiva Chidambaram is a research scientist at MIT. He joined the collaboration 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.

Angelica Babei

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.

Andrew Booker

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.

Sonal Jain

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.

Alexander Betts

Betts is 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.

Ben Breen

Ben Breen received his Ph.D. at Dartmouth College in June 2020. He is currently 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

Ciaran Schembri

Ciaran Schembri is a research scientist at Dartmouth College. He joined the collaboration 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.
