Helmut Pottmann is a professor of geometry at Vienna University of Technology, where he directs the research group Geometric Modeling and Industrial Geometry at the Institute of Discrete Mathematics and Geometry. He has held faculty positions at the University of Hamburg, University of Kaiserlautern, Purdue University, University of California at Davis, and Tsinghua University in Beijing. His most recent research focuses on the development of geometric methods and algorithmic tools for the design and manufacture of complex freeform structures in architecture. Michael Hofer is a post-doctoral researcher at Vienna University of Technology. He received his doctoral degree in Applied Geometry in 2005 and was employed at the University of California at Davis and the University of Minnesota. Since 200 he has regularly taught geometry to undergraduate and graduate students of architecture. His research focuses on the solution of geometric problems in applications such as computer-aided design, computer graphics, and image processing. Andreas Asperl studied Mathematics and Descriptive Geometry at Vienna University of Technology, where he has held a faculty position since 1983. He is also a teacher of geometry and CAD for a gymnasium in Vienna, author of several textbooks for use in Austrian schools at different levels, and a main promoter of the use of three-dimensional CAD systems in geometry education. Axel Kilian studied Architecture and specialized in Design and Computation for a Masters of Science, a Ph.D., and a post-doctorate at the Massachusetts Institute of Technology. He has been teaching workshops in computational design and design studios and has lectured on the topic of generative design widely at schools and in the context of the Smart Geometry group events.
