Before that, I was a Research Associate in the Institute of Media Informatics at Ulm University, Germany with Enrico Rukzio.
In 2023, I visited Cornell Tech, working in the Future Automation Research Laboratory led by Wendy Ju.
Before starting my PhD, I was a Software Engineer at Airbus Defence and Space.
I defended my PhD thesis in April 2024 entitled "Calibrating Trust in Automated Vehicles - Theoretical, Design, and Empirical Insights into Effects of Visualizations on Trust".
My multidisciplinary research in Human-Computer Interaction (HCI), Accessibility, and Computational Modeling and Simulation is dedicated
to tackling complex challenges and seizing opportunities within advanced mobility technologies. It involves designing, implementing, and testing novel simulators to study futuristic mobility scenarios. My work aims to address issues such as undertrust
in automated vehicles and to enhance accessibility in urban (air) mobility, thereby supporting societal and industrial growth.
A significant portion of my research focuses on evaluating innovative interaction paradigms between automated vehicles and
vulnerable road users, utilizing empirical evidence alongside simulation-based approaches to analyze their broad-scale impacts.
Three papers have been accepted to IMWUT. In AutoTherm, we present two datasets regarding thermal comfort prediction with an ablation study. With "Move, Connect, Interact: Introducing a Design Space for Cross-Traffic Interaction", led by Annika Stampf, we aim to re-define interaction in connected traffic. Finally, we have been "Examining Psychological Conflict-Handling Strategies for Highly Automated Vehicles to Resolve Legal User-Vehicle Conflicts", also led by Annika Stampf.
Our paper "Hey, What’s Going On? Conveying Traffic Information to People with Visual Impairments in Highly Automated Vehicles: Introducing OnBoard" was accepted at IMWUT. We conducted an
interactive, participatory workshop (N=4) to develop an auditory interface and OnBoard- a tactile interface with expandable
elements - to convey traffic information to visually impaired people. In a user study with N=14 participants, we explored
usability, situation awareness, predictability, and engagement with OnBoard. Pre-print available under this LINK.

Our paper "Law and Order: Investigating the Effects of Conflictual Situations in Manual and Automated Driving in a German Sample" was accepted for IJHCS (IF 5.4). We conducted two studies: one involving an online survey and a Virtual Reality experiment that explored how the obligation of automated vehicles to strictly adhere to traffic laws influences user-vehicle conflicts and trust, revealing a preference for legal compliance but a willingness to override for personal interests. Pre-print available under this LINK.

Mobility serves as a cornerstone for societal advancement and industrial growth.
As we move towards automated systems and explore unconventional transportation methods
like urban air mobility, we face a dichotomy of challenges, such as "undertrust" in technology
and opportunities like enhanced accessibility. My multidisciplinary research spans
Human-Computer Interaction (HCI), Accessibility, and Computational Modeling and Simulation to achieve
three core objectives:
Characterizing Novel Mobility Systems: Conducting empirical studies to unearth
the challenges and opportunities associated with emerging forms of mobility, particularly focusing
on accessibility issues.
Behavioral Analytics: Investigating the travel behaviors of both the general
populace and vulnerable groups to better understand their unique needs and risks in various
traffic scenarios.
Human-Centric Solutions: Leveraging insights from the above studies to design
and implement solutions—ranging from technical prototypes and guidelines to industrial collaborations
and educational initiatives—that aim to make traffic safer and more accessible for all.
Publications (Excerpt)
I have published more than 30 first-author publications and have contributed to numerous further ones. My most significant research contributions have been published in leading HCI conferences and journals like CHI (13 full paper publications) and IMWUT (11 full paper publications).
