I organized the Graduate Student Number Theory Seminar at Rutgers in the fall of 2018. You can find more information about it by visiting the Fall 2018 Rutgers Graduate Student Number Theory Seminar website.
In the spring of 2019, I organized the Number Theory Learning Seminar at Rutgers. You can find more information about it by visiting the Spring 2019 Number Theory Learning Seminar website.
After me, the Rutgers Graduate Number Theory Seminar/Learning Seminar was run by Brooke Logan Ogrodnik.
