Halo, I’m Ran Zhang!
I'm a postdoctoral researcher in Human Computer Interaction Lab at Hasso Plattner Institute, working with Prof. Patrick Baudisch.
I got my PhD from IST Austria in 2020, supervised by Prof. Bernd Bickel, and supported by MSCA-ITN DISTRO project. Previously, I got my Master degree from the University of Science and Technology of China(USTC) in 2014, supervised by Prof. Xuejin Chen and Prof. Ligang Liu; and a Bachelor degree from Tianjin University in 2011.
I'm a Computational Design Researcher(CoDeR), my current research interests include Developable surfaces, 3D Linkages and Non-manifold mechanisms.

In our SIGGRAPH 2017 paper: Functionality-aware Retargeting of Mechanisms to 3D Shapes, We present an interactive design system to create functional mechanical objects. Our computational approach allows novice users to retarget an existing mechanical template to a user-specified input shape.
Scissor structures are used to generate deployable objects for space-saving in a variety of applications, from architecture to aerospace science. While deployment from a small, regular shape to a larger one is easy to design, we focus on a more challenging task: designing a planar scissor structure that deploys from a given source shape into a specific target shape. We propose a two-step constructive method to generate a scissor structure from a high-dimensional parameter space. Topology construction of the scissor structure is first performed to approximate the two given shapes, as well as to guarantee the deployment. Then the geometry of the scissor structure is optimized in order to minimize the connection deflections and maximize the shape approximation. With the optimized parameters, the deployment can be simulated by controlling an anchor scissor unit. Physical deployable objects are fabricated according to the designed scissor structures by using 3D printing or manual assembly.
