Description
André Calero Valdez is a senior researcher at the Chair for Communication Science and the Human-Computer Interaction Center at the RWTH Aachen University.
He studied computer science at the RWTH-Aachen University with a minor in psychology and has specialized in software engineering. His dissertation aimed at the development and evaluation of a usercentred small screen device for diabetes patients. His dissertation was funded by the RWTH Aachen postgraduate scholarships for students with excellent degrees.
Since 2013 André works as a post-doctoral research at RWTH Aachen University and works at the interface of algorithms and humans in various fields of application. He works in the fields of empirical social research, technology acceptance, eHealth, Industry 4.0, recommender systems, information visualization and social media.
