Welcome to the COMPUTER-AIDED DESIGN (CAD) web page.

CAD has many different aspects, ranging from the design of graphical user interfaces to algebraic and numerical problems in geometry. The research activity in the Department is concentrated on the latter, and especially on issues of computational robustness of the representation and manipulation of curves and surfaces.

Projects include

1. Data exchange

2. Representations of curves and surfaces

3. Resultants

Papers and reports on these topics are in my publications page.
