current research interests
Since mid-2015, I've been a research associate in the Virtual Worlds and Digital Games Group at Ilmenau University of Technology. My PhD is about the impact, possibilities, and limitations of XR on future in-vehicle user interfaces. Next to that, I'm very keen on HCI and human factors in XR technologies. I have completed my PhD in 2021. Now, I'm a postdoctoral researcher at the in the Virtual Worlds and Digital Games Group at Ilmenau University of Technology, focussing on haptic user interfaces for virtual and augmented reality.

I implemented a plug-in for the visualization software Amira. The software solution allows medical personnel to fuse a stream of intraoperative thermographic images of the cortex with a preoperative 3D-MR brain image. The plug-in is based on a calibration-based image registration algorithm processing tracking data delivered by a neuronavigation system. For the evaluation of image fusion, a imaging phantom simulating the brain, brain shift, perfusion and trepanation was built.

Title: Implementation and Performance Evaluationof Passive Replication For StreamMine3G (1,3)
During the intense months of my bachelor thesis, I implemented a passive replication mechanism for StreamMine3G. StreamMine3G is a complex event processing engine. My contribution is the mentioned fault-tolerance protocol which handles checkpointing as well as replaying events in case of the failure of one or more parts of the system.

For one semester, my job was to supervise/mentor three groups of students and help them with their software project.
09/2003 - 02/2007 Apprenticeship - Mechatronics Technician (Braun GmbH)
For 3.5 years I have done an apprenticeship as a mechatronics technician and completed it successfully. During this time, I gained considerable knowledge in the field of mechanics, electronis and maintenance of industrial machinery. Furthermore, I was lucky to get a broad insight into the organization and structure of a worldwide operating company. Besides that, the work with different people in different departments as well as dealing with superiors in an appropriate way was an important experience. After the apprenticeship I worked at Braun for 2.5 more years. Six months full-time and two years part-time while doing my university-entrance diploma (A levels).
I designed a flyer which visualizes the relationship of computer science and the SLUB.(Adobe InDesign, Adobe Photoshop, Adobe Illustrator)
We programmed an application for controlling Smart Homes. The user is able to create rules using the input data of sensors in order to execute actions with registered actuators.(WAMP, Drools, Java, Android)
Our team developed a multitouch visualization software which enables the user to explore the historic development of the SLUB.(Java, Processing, Surface Tabletop)
We developed an Android application which displays objects in a so-called fish-tank environment. According to head-position and viewing direction of the user, position and orientation of the object is updated. This creates the effect of a head-coupled perspective. In addition to the Android app, we programmed a server application for communication between the head-tracking system and the android device.(Motive, C++, Android, Multi-Threading, WinSock)
