I have a wide range of interests in the general area of computing, often crossing into other fields such as medicine, civil, industrial and manufacturing engineering. My students and I have done research in fundamental graphics algorithms, curve and surface modeling, geometry processing for solid modeling and manufacturing, surface and volume triangulations, terrain modeling, genetic algorithms, reverse engineering, NURBS, bio-engineering, knowledge-guided computation and fault-tolerant design.


I am currently working on two projects. One is in 3-D printing and the other in cyber learning. In 3-D printing my team is addressing the issue of object slicing based on a point cloud model of the precise geometry. In cyber learning we are looking into improving the fundamental way learning takes place in an Internet-enabled interconnected world.
