• Potential advisor/consultant(s): David Eisenbud and Mike Stillman
• Goal: Fast integral closure with good interface and output
• Current status: Many subprograms and packages written; needs consolidation. Collaborators welcome.
• Macaulay2 skill level: Intermediate
• Mathematical experience: Grad commutative algebra, algebraic geometry desirable

Fractional ideals and Noether normalization -- smooth out interface

Puiseux series and integral bases for plane curves (and a version for finite characteristic with Frobenius)

Fast integral closure of plane curves will be a milestone

Need easy ways to adjoin roots in fields

Work over finite fields, lift to char 0

Work over function fields (Hensel lifting?)

Early milestone: unify pushfwd (in the PushForward package) with the internal pushForward command
