Research: Original Scientific Discoveries

Professionally, I am a pure mathematician working in the Topology of High-dimensional Manifolds (CV/résumé).
Partial funding for research is provided by the National Science Foundation, through a grant of which I am the Principal Investigator (DMS-0904276).
From Fall Semester 2010 through Spring Semester 2012, I serve as the organizer of the Notre Dame Topology Research Seminar.

PUBLICATIONS (original work, refereed by anonymous expert)

Immediately after each publication number on the left, you will find the 2010 Journal Quality Ranking of the Australian Research Council:

A* = one of the best in its field or subfield   |   A = very high quality   |   B = solid, though not outstanding   |  
C = does not meet the criteria for the higher tiers   |   N/A = ranking not available because the journal is too new
