I am head of the Computer Science Study Center and coordinator of the Examination Committee for Computer Science at RWTH Aachen University.
I am also an Affiliated Researcher at the Media Computing Group of the RWTH Aachen. Between 2016 and 2020, I was deputy chair of the Media Computing Group. My research area is Human-Computer Interaction (HCI) and I mainly work on mobile interactions, ubiquitous computing, personal fabrication, touch input, interactive surfaces, and tangible user interfaces.
I am in charge of the following responsibilities:
- Examination board computer science
- Coordination of the teaching of the computer science department
Students can submit requests to the Computer Science Examination Board via web form.

abstract = {Toolkits like the Arduino system have brought embedded programming to STEM education. However, learning embedded programming is still hard, requiring an understanding of coding, electronics, and how both sides interact. To investigate the opportunities of using a different programming paradigm than the imperative approach to learning embedded coding, we developed Flowboard. Students code in a visual iPad editor using flow-based programming, which is conceptually closer to circuit diagrams than imperative code. Two breadboards with I/O pins mirrored on the iPad connect electronics and program graph more seamlessly than existing IDEs. Program changes take effect immediately. This liveness reflects circuit behavior better than edit-compile-run loops. A first study confirmed that students can solve basic embedded programming tasks with Flowboard while highlighting important differences to a typical imperative IDE, Ardublock. A second, in-depth study provided qualitative insights into Flowboard's impact on students' conceptual models of electronics and embedded programming and exploring those.},

abstract = {Soft robotics uses soft, flexible materials and elastic actuation mechanisms to create systems that are more adaptable and tolerant to unknown environments, and safer for human-machine interaction, than rigid robots. Pneumatic soft robots can be fabricated using more affordable materials compared to traditional robots and make use of technologies such as 3D printing, making them an attractive choice for research and DIY projects. However, their design is still highly unintuitive, and at up to two days, design iterations can take prohibitively long: The behavior of, e.g., a pneumatic silicone gripper only becomes apparent after designing and 3D printing its mold, casting, curing, assembling, and testing it. We introduce SoRoCAD, a design tool supporting a Maker-friendly soft robotics design and fabrication pipeline that incorporates simulating the final actuation into the design process.},

abstract = {We present BendDesk, a hybrid interactive desk system that combines a horizontal and a vertical interactive surface via a curve. The system provides seamless touch input across its entire area. We explain scalable algorithms that provide graphical output and multi-touch input on a curved surface. In four user studies, we investigate the performance of dragging gestures across the curve, as well as the perception of lines on the surface. Our main findings are: 1) Dragging across a curve is significantly slower than on flat surfaces. 2) The flatter the angle when dragging across the curve, the longer the average trajectory and the higher the variance of trajectories across users. 3) The curved shape of the system impairs the perception of lines crossing both surfaces.},

abstract = {BendDesk is a curved interactive display that merges a vertical and a horizontal multi-touch surface with a curve. Users sitting at the table can perform multi-touch input on the entire surface. This demo shows the capabilities and potential applications of such a setup. We also present Bend Invaders, one of the first arcade games on a curved interactive surface. Our demo intends to encourage the discussion about the future of multi-touch in desk environments.},
