current research interests

Since March 2023, I'm a postdoctoral researcher at Lancaster University with Prof. Hans Gellersen. My research focusses (again), on multi-sensory XR, this time focussing on AR experiences integrating gaze behavior and body movements. The work takes place in the context of the GEMINI ERC project at the School of Computing and Communications at Lancaster University.

From March 2021 to March 2023, I was a postdoctoral researcher in the Virtual Worlds and Digital Games Group at Ilmenau University of Technology. Here, I did research on multi-sensory XR and focus on touch/haptics. My PhD was about the impact, possibilities, and limitations of XR on future in-vehicle user interfaces. Here's a link to the group's homepage.

Title: Development and Evaluation of an Amira Plug-In for Image Fusion of intraoperative Thermography with MRI in Neurosurgery (1,4; text/en, slides/de)

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.

After I had analyzed existing code, I developed an extension which enables a TurtleBot to play custom sound files. Furthermore, I introduced an extension manager for handling the sound as well as other extensions appropriately.
(Java, ROS)

02/2013 - 03/2014 Student Assistant - Professur für Softwaretechnologie, TU Dresden (DeltaEcore)

I developed an Eclipse plugin based on GEF to load, display and modify meta models. For this, I had to design the graphical representations for the single model elements as well as layout them in an appropriate manner.

04/2012 - 07/2012 Student Assistant - Working Group DIL, TU Dresden

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).

Computer Science and SLUB

I designed a flyer which visualizes the relationship of computer science and the SLUB.

Our team developed a prototype of a TableLens for visualizing multivariate data using focus and context as well as zoom and overview techniques.
(HTML5, CSS3, jQuery, JavaScript)


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)

The History of SLUB

Our team developed a multitouch visualization software which enables the user to explore the historic development of the SLUB.
(Java, Processing, Surface Tabletop)

Head-Coupled Perspective

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)

Interaction in virtual environments (Video on YouTube)

The goal of this group project was development of an interaction scheme for virtual environments. With an Android or WindowsPhone app the user is able to explore virtual environments like a museum either in free or semi-automatic mode along a predefined route.
(Unity3D, C#, JavaScript, WindowsPhone, Android)
