He is a member of the IFIP Working Group WG 13.5 (Resilience, Reliability, Safety and Human Error in System Development).
In addition to academic research, he is a strong advocate of the societal impact of HCI. He has enthusiastically worked with clinicians in various fields of health (e.g., physical rehabilitation, neurology, emergency medicine) as well as with safety experts in various areas (e.g., aviation safety, fire prevention, first response) to create innovative applications for real-world use. Two of his medical apps are currently in hospital use, while his aviation safety apps have received great attention from the public and the media, with over 18 million installations as of April 2023. They have also been featured on major TV stations such as Fox News and Discovery Channel as well as major news web sites such as TIME, Popular Mechanics, and Gizmodo.
