My profession is mathematics and theoretical computer science. I have studied at the University of Zagreb (B.S. 1995) and Carnegie Mellon University (M.S. 1998, Ph.D. 2000). I worked as a professor of computer science at Arizona State University from 2000 until 2010. Since 2010, I've worked at the Lawrence Livermore National Laboratory. This out-of date mirror of my old ASU web page covers that part of my life in some detail.
Origami has been a hobby of mine for a long time, but I mostly folded from others' instructions. Not until 2005 did I start seriously exploring the possibility of original work in origami.
Most of my pieces so far are abstract shapes naturally formed by the tension of the paper when multiple layers of paper are arranged according to regular or irregular patterns. In that sense, they could almost be said to be discovered, rather than invented or designed. In particular, the pieces shown in my pleat tessellation gallery pages have been developed from a single urform discovered by Paul Jackson. The experience of folding these pieces has helped me begin to understand how particular fold sequences interact and in a few cases I have been able to visualize the final shape before starting to fold.
I try to restrict myself to working with single uncut sheets of paper or other foldable material (such as copper), and for the most part use very simple “pureland” folds. Normally, this last restriction would imply that the resulting forms are flat. However, a real sheet of paper is always three-dimensional—even when unfolded—and its thickness brings about a much more obvious three-dimensionality when multiple layers are present.
