I am the Sara Kiesler Assistant Professor at the Human-Computer Interaction Institute at Carnegie Mellon University's School of Computer Science. I lead the Interactive Structures Lab, where we investigate and develop interactive design tools that enable digital fabrication of complex structures for novice users.

HCI + computational geometry + engineering + design

Interactive structures embed functionality within their geometry such that they can react to simple input with complex behavior. Such structures enable materials that can, e.g., embed robotic movement, can perform computations, or communicate with users. We focus on material discovery by broadening participation. We develop optimization-based interactive design tools that enable novices to contribute their creativity and experts to apply their intuition in order to foster the advancement of high-tech materials. We investigate the entire pipeline, i.e., their mechanical structure, the algorithms for efficient design, the unforeseen application areas and fabrication methods.

We are always open for ambitious and interested students join the team!
