Research Interests
Algebraic
number theory, especially Iwasawa Theory, L-functions, and
computations in algebraic number fields. My work has focused on
unravelling some of the mysteries of algebraic number theory embodied
by Stark's conjecture, Leopoldt's conjecture, and unresolved questions
in classical Iwasawa theory.
