When describing real world objects on a computer we typically must first describe their shape. My research focuses on geometry processing addressing the algorithmic challenges which arise in digital shape modeling and manipulation. I am particularly interested in discrete geometry representations and specifically meshes (polygonal model representations). The main application areas of this research are computer graphics and computer aided engineering applications. My work utilizes tools from computational and differential geometry, discrete math, and graph theory to generate, manipulate, and edit discrete geometric models.
