About
I am a research associate in the Human-Computer Interaction group at the University of Hamburg. I have submitted my PhD thesis, and my defense is planned for November 2026. I am interested in exploring how technology can support us in interacting with the real world. In particular, my interest lies in AR and immersive technologies in general.
I design concepts together with the people who use them, develop applications to be deployed in the real world, and study their effectiveness and perceived usefulness in field studies.
Research Projects
During my PhD at the University of Hamburg, I was involved in several research projects, mostly third-party funded and one commissioned by industry, in close collaboration with industry and research partners.
2025 – 2026
Funded by EU Horizon
A toolset for hyper-realistic and XR-based human-human and human-machine interactions
Development of technologies for more convincing presence in extended reality (XR), organized in three technical pillars with one SDK each: holoportation, haptics, and intelligent virtual humans.
Role
- Co-leading the technical committee
- Co-leading the technical pillar on intelligent virtual humans, developing an open-source Unity SDK for creating them
- Conducting the user-centered evaluation of all technical pillars
Main publications
2023 – 2025
Funded by BMV
Strategic port planning based on digital twins
Development of a port planning tool based on a digital twin that enables collaborative planning and simulation of traffic scenarios. As a technical platform, we explored a multi-touch table in combination with AR.
Role
- Developing the port planning tool (3D visualization and interaction)
- Conducting the user-centered evaluation
Main publications
2023 – 2024
Funded by BMFTR
Dynamic situation creation and support for rescue forces in complex crisis situations
Creation of a dynamic situational picture of crisis and disaster situations from continuously integrated real-time data, giving rescue forces comprehensive orientation and situation assessment.
Role
- Contributing to the research grant proposal
- Leading the requirement analysis for the situational picture
Main publications
2022 – 2025
Commissioned research for Hamburger Energienetze via HITeC Hamburg
AR Inspection Support for Gas Facilities
Investigation of how AR can support technicians in inspecting facilities of the local gas network operator. Together with stakeholders, especially technical staff, we identified requirements in a user-centered process and developed a prototype, with use cases such as 3D visualization of installed components, digital forms in AR, and the display of underground pipelines.
Role
- Analyzing the requirements of technicians
- Developing prototypes in an iterative process
- Conducting a long-term field study to evaluate the final prototype
Main publications
2020 – 2023
Funded by BMBF
Knowledge networking and collaboration through augmented reality in production-related services
Development of a digitalization assistant that makes AR/VR more accessible to small and medium-sized enterprises by supporting the development of AR/VR applications with a no-code/low-code approach.
Role
- Exploring visualization and interaction paradigms
- Developing and evaluating AR/VR prototypes
