Research Interests

I am a post-doc at the media informatics department. My research delves into the interaction in immersive virtual systems with Head Mounted Displays (HMDs) - in a co-located setting.

VR uses our visual dominance to deliver virtual experiences, making users believe that they are in another reality. However, while their mind is present in VR their body is in the physical reality. From the user's perspective, this brings considerable uncertainty to the interaction, especially in a co-located setting.

I investigate this uncertainty by developing interfaces that enable users to stay in VR while supporting their awareness of the physical reality. They maintain this awareness without having to take off the headset - which I refer to as seamless interaction with the physical reality.

The overarching research vision that guides this thesis is, therefore, to reduce this disconnect between the virtual and physical reality. More specifically, I am interested in the following research questions:

How to communicate with co-located collaborators while wearing a HMD?
How to manage presence between the virtual and physical reality?
How to maintain privacy and security in a co-located setting with HMDs?
How to physicalize hidden data from the virtual to the physical reality?

Prior to starting my research at LMU, I was working in Digial Product Development as a Senior Product Manager. More details on my industry work experience can be found on my linkedin profile. My publication list can be found on my Google scholar profile. Below are some selected publications in pre-print version. Preprint of my thesis

Dissertations (Bachelor/Master)
