**RESEARCH INTERESTS**

My primary area of research includes low dimensional topology, particularly 4 -dimensional topology, geometry, and gauge theory. These have been dynamic fields for the past 25 years and have close ties with many other areas of research: geometric analysis, mathematical physics, string theory, and knot theory are just a few.
