Stob will continue his work in recursion theory, a branch of               mathematical logic which formalizes the notion of computability.                He intends to study the structure of the lattice of recursively                 enumerable sets and the upper semilattice of recursively                        enumerable degrees.  In particular, Stob will attempt to settle                 conjectures about orbits under automorphisms of the lattice of                  recursively enumerable sets, automorphism types of splittings of                creative sets, and isomorphism types of lattices of supersets of                r.e. sets.  Stob will also attempt to answer questions about the                Turing degrees of various natural classes of r.e. sets and will                 attempt to settle two questions about minimal pairs in the r.e.                 Turing degrees.
