ABSTRACT
In this talk I will present geometric manipulation techniques for shapes in 3D and 2D that are based on differential representations. Such representations encapsulate important local shape properties and enable a variety of useful operations, which preserve the local details of a shape, and thus its appearance. I will discuss several geometry processing and shape modeling applications based on the differential framework, such as quantization of geometric information, detail-preserving mesh editing, shape interpolation, surface detail transfer and feature-aware image warping. We will see how the geometric deformation mechanisms can be effectively combined with intuitive user interfaces to allow interactive free-form deformation and sketch-based editing of complex shapes.

BIO
I'm a postdoc researcher at the Computer Graphics Group of TU Berlin, supported by the Alexander von Humboldt Foundation. I'm working with Prof. Marc Alexa and his group. I recently finished my PhD at the School of Computer Science, Tel-Aviv University, under the supervision of Prof. Daniel Cohen-Or.

My research interests lie in the field of Computer Graphics; in particular, I concentrate on interactive geometric modeling, shape approximation, shape and image manipulation, computer animation and expressive modeling techniques. I enjoy teaching, especially mathematical tools for Graphics.
