| Research Statement |
| | Joe Warren's research interests focus on the application of computers to geometric problems and are centered around the general problem of representing geometric shapes. His specific areas of interest include geometric modeling, or the construction and manipulation of data structures for representing geometric objects, and computational geometry, or using algorithms to solve geometric problems. He is particularly interested in algorithms for solving and manipulating systems of polynomial equations. His approach is to develop interesting mathematical methods for representing shape that can be used in practical applications. Topics he has worked on include modeling with piecewise algebraic surfaces, methods for finite-element mesh generation, properties of rational surfaces with base points, and visualization of multivariate data. Warren's current research focuses on two related topics: subdivision, a method for concisely representing shape, and wavelets, a method for building an associated hierarchy of shapes. He is particulaarly interested in extending the theory associated with both to handle irregular geometry. |

| Computer Graphics and Geometric Modeling: From Advanced Mathematics to Real World Applications |
| |
One of the principal areas in which computing has changed the today's world is computer graphics and geometric modeling. In entertainment, computer-animated movies such at "Finding Nemo" and advanced 3D computer games such as "Halo 2" make heavy use of computer graphics. In medicine, computer graphics allows physicians to visualize and simulate disease processes and potential treatments in ways that were never available until now. In manufacturing, geometric modeling allows engineers to design and test goods without the need to build costly physical prototypes.
All of these advances are based on algorithms and data structures developed by computer scientist for representing, simulating and visualizing geometric objects. At the core of these advances is an exciting synthesis that arises from combination of new computational techniques with existing mathematical disciplines such as algebraic geometry and differential geometry. Professor Warren's research lies at exactly this boundary. His goal is to apply advanced mathematics to real world problems and develop new methods in computer graphics and geometric modeling for solving these problems.
