To set up a meeting, please see my basic schedule, then contact my administrator, Clarissa de Gavarelli.

Jan Borchers is a full professor of computer science and head of the Media Computing Group, an endowed Chair in the Computer Science Department at RWTH Aachen University.

With his research group, he explores the field of Human–Computer Interaction (HCI), with a particular interest in new user interfaces for soft robotics, textile user interfaces, 3D printing and personal fabrication, augmented reality, wearable and tangible computing, interfaces for software development, deceptive patterns, and interactive guides and exhibits. In 2009, he opened Germany's first Fab Lab.

Jan established his group in 2003 and pioneered conducting modern HCI academic research and teaching in Germany [1]. It soon became a leading German lab in terms of archival publications at CHI, the top international conference in HCI. Before joining RWTH, he held faculty positions at Stanford University and ETH Zurich, after receiving his PhD 'summa cum laude' in computer science from Darmstadt University of Technology in 2000. His PhD thesis, A Pattern Approach to Interaction Design, became the first book to bring the concept of design patterns to HCI.

He is a member of ACM, SIGCHI, SIGCHI Germany, and GI, and introduced the Interactivity format to the CHI conference in 2005. He has also provided usability talks, training, and consulting, as well as user interface design, prototyping, and evaluation, to clients such as AirBus, Apple, ARD, Bayer, Children's Museum Boston, Daimler, Handelsblatt, OTIS, Scout24, TEDx, and Deutsche Telekom.

You can find him on BlueSky @janborchers, on Mastodon @janborchers, and on X/Twitter @borchers. For urgent matters, please contact his assistant, Clarissa de Gavarelli.
