Open to mentoring Bachelor, Master, and PhD students.

I am a tenure-track Lecturer/Assistant Professor in HCI at the UCL Interaction Centre.

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.

April 2026
I am thrilled to announce that I have been selected as a 2026 ABSW Media Fellow! Supported by UCL, I will be spending two to six weeks embedded in a major UK media outlet later this year. I look forward to working directly with science journalists to bridge the gap between academia and the media, and to find new ways to communicate our HCI and future mobility research to a broader public audience.


February 2026
I am a Visiting Professor at the University of Tokyo, supported by the Canon Foundation Research Fellowship, in the User Interface Research Group led by Takeo Igarashi.

January 2026
I joined the ACM Transactions on Computer Human Interaction (TOCHI) Distinguished Reviewer Board. Furthermore, 10 papers that I worked with amazing co-authors were conditionally accepted to CHI'26. See you in Barcelona.

Accessibility, Mobility and Computational Modeling and Simulation

Mark Colley

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:

  1. Characterizing Novel Mobility Systems: Conducting empirical studies to unearth the challenges and opportunities associated with emerging forms of mobility, particularly focusing on accessibility issues.
  2. 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.
  3. 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.
