Dr. Christian P. Janssen

About me

I am interested in understanding adaptive human behavior and human-automation interaction, especially in the mobility domain. How do cognitive characteristics, task characteristics, and context shape human behavior and performance? And how well can people optimize their performance given these constraints? Of particular interest are human behavior in mobility settings, and are phenomena such as multitasking, distraction and attention, and interaction with automated systems such as autonomous cars. I investigate these research topics together with students and colleagues at the Division of Experimental Psychology (in Dutch) at Utrecht University. I am also co-director of the ICAI lab on AI and mobility lab, a cross-disciplinary lab where we collaborate with non-academic partners on research at the intersection of AI and mobility.
My research uses a combination of empirical studies and computational modeling and computer simulations. I contribute both to theory and to applied settings. For the more applied components, I collaborate and publish with colleagues in industry and government institutes.

May 2023: Recruiting two PhD students
I am recruiting two PhD students for projects on AI, Cognitive Modeling, and mobility. All intended to start in September 2023:

• Position 1: Cooperation between Human Operators and AI Algorithms in the Railway Sector (deadline May 21st, Dutch language requirement). Future planning of rail infrastructure usage requires a dynamic approach in which human operators interact with automated planning tools to jointly optimize the planning process. This requires both novel, yet-to-be-developed algorithms (AI), and a redefinition of the role that the human operator plays in the automated planning loop. Moreover, such algorithms and human operations need to be understood in the real world, in actual contexts of work, to tie scientific theories to everyday practice. This PhD research project will investigate how humans operate in the logistical planning process of the railways, as well as how the contribution of automated planners can be made insightful for human operators and vice versa. Supervision by myself, Dr. Leendert van Maanen, Dr. Silja Renooij, and Prof. Dr. Mehdi Dastani. In collaboration with NS and ProRail. See: Position
• Position 2: Digital twins for mobility (more details to follow).

December 2020: New course to be developed "AI for an Open Society"
Together with my colleague Leendert van Maanen, I received a grant from the central university board to develop a new BSc level interdisciplinary course called "AI for an Open Society". The course will be open to students from all Bsc programs in Utrecht, and will be taught with colleagues from the social sciences, humanities, and economics and law faculty. We will teach how insights from these disciplines (e.g., cognitive models, behavioral change, ethics, management) can help to better understand how AI models, technology, and methods influence and shape society. Think of the effect AI has on filter bubbles and polarization, on the future of work, etc. I'm particularly excited about the opportunity that through this course we can reach a wide set of students that will be better prepared for the various changes that society is going through, and that they see what the implications of AI are beyond tech. It can also build on the strong Utrecht expertise on Human-centered AI and Institutions for an Open Society.

November 2020: New video on human-automation interaction

November 2016 Nominated for "senior lecturer of the year" in psychology
I was very proud and humbled to receive news this week that I was nominated by my colleagues for the Maarten van Son "senior lecturer of the year in psychology" award.

November 2016 Paper accepted
A paper from my time at Smith-Kettlewell just got accepted for publication in Journal of Vision! In the paper we describe a method in which we try to teach people with macular degeneration to make more efficient eye-movements to compensate for visual sight loss. This was a very challenging project, in which I learned many new skills. I am very proud of the result

February 2015 Lots of good news!

• A paper got accepted for the journal of vision - one of the leading journals on vision sciences. The paper is: Janssen, C.P. & Verghese, P. (2015). Stop before you saccade: Looking into an artificial peripheral scotoma. Journal of Vision, 15(5) article 7:1-19 doi:10.1167/15.5.7.[Publisher URL]. In this paper we investigate what strategies people use to perform an object-comparison task when part of the screen is hidden by an artificial scotoma (a blindspot). Apart from being motivated by theoretical work, this paper also forms a useful fundament for my more clinical work with patients who have macular degeneration (work done at Smith-Kettlewell, paper in preparation).
• I received a small grant from Utrecht's Neuroscience and Cognition program group. The grant will be used to start a new research line together with Prof. Leon Kenemans and Dr. Matthijs Vink (University Medical Hospital) looking at the ability to detect and respond to unexpected events while multitasking in automated environments.
• Recent work with Preeti Verghese got accepted for oral presentation at ARVO. The work is entitled "Scotoma Awareness and Eye Movement Training in Age-Related Macular Degeneration" and discusses our recent work that looked at ways to make eye-movements more efficient for patients with vision loss due to macular degeneration - one of the leading causes of vision loss. See also my description of this work here. ARVO is the largest conference of vision and eye researchers in the world, with over 11,000 attendants.
• The work of my MSc student Kimberly Hulleman made it to the local papers. Kimberly is investigating the potential impact of autonomous driving on hazard detection. The research is being conducted at the SWOV Institute for Road Safety Research. Read the article here
