My research has been in the area of singularity
theory and its application to nonlinear problems. It has
specifically concerned :

1) the relation between smooth and
topological stability of mappings

2) establishing the basic
theorems of singularity theory (unfolding, determinacy theorems, and
infinitesimal characterizations of local stability) for equivalences
preserving additional structures for smooth or holomorphic
mappings

3) establishing topological analogues of these
theorems with applications to topological stability and
equisingularity

4) applications to invariants and
classification for bifurcation theory

5) local structure of
nonlinear Fredholm operators

6) singular Milnor fibers and
their applications for nonisolated complete intersections, including
discriminants and nonlinear arrangements of hypersurfaces

7)
determining the freeness of discriminants and bifurcations sets for
versal unfoldings for general equivalence groups

8) solvable group representations yielding free divisors, and
their application to determining the vanishing topology of nonisolated
matrix singularities

9) Topology of exceptional orbit hypersurfaces
of prehomogeneous spaces, including the varieties of m x m singular matrices,
which are general, symmetric or skew-symmetric

10)singularity theory for solutions to PDE's with applications to
computer medical imaging

11) scale-based methods for
computer imaging

12) local and relative geometry of objects
and their boundaries from medial data; global geometry via skeletal
and medial integrals, and characterizing complexity of 3D regions via
graph structures

13) the analysis of multi-object configurations
via medial/skeletal linking structures capturing both shape and geometry of
individual objects and the positiona lgeometry of the configuration

14) determining the evolving self-intersections
of evolving surfaces defined by splines and the application to computing
medial axes for regions defined by splines

15) using singularity theory for mappings on special semianalytic
stratifications to determinine the local structure in natural images allowing
shade/shadow, geometric features, and apparent contours, for both stable views
and transitions under viewer movement.
