About me

Portrait of Beren

Hi there! My name is Beren. I'm a German citizen and currently a Ph.D. candidate at the Human-Computer Interaction Group led by Michael Rohs at the University of Hannover in Germany.

I'll finish my Ph.D. in May 2021, and I'm actively looking into attractive Swiss work opportunities which fit my skillset around AI, VR/AR, and tactile feedback. Besides exciting work opportunities in the greater Zurich area, I especially like the Swiss mentality, lifestyle, and gorgeous landscape.

During my Ph.D., I focused on tactile feedback in Human-Computer Interaction. My main Ph.D. project is called HapticHead, a 24 tactile actuator display on the head. This interface can be used in Augmented and Virtual Reality scenarios for various applications such as guidance and navigation for visually impaired individuals or increasing immersion in VR scenarios by playing back tactile features of the virtual world. Imagine a raindrop hitting your head exactly where you would expect it to hit or feeling the impact of an explosive shockwave.

Apart from my main Ph.D. topic, I had the freedom to work on several side projects, mostly in Artificial Intelligence, as I find AI applications to be a fascinating research direction. Notably, I developed the Ahem preventor, a system that detects filler words in oral presentations and discretely gives presenters concealed tactile feedback whenever they use a filler word. This system may train oneself to use fewer filler words in presentations subconsciously. Another exciting project revolved around grading the damage level of concrete through ultrasonic signals and a neural network in collaboration with a colleague from material sciences.

As a side hustle, I developed and supported three iOS and several Android apps for miovent.de, a small agile event company and subsidiary of eventit.ag and Deutsche Messe AG.
