[2] Ullman has developed a number of inventions, first and foremost related to ergonomics, injury prevention, medical technology, work environment and IT.

In 1996, at Sahlgrenska University Hospital, Ullman developed a method for measuring exposure to human whole-body impact on board high-speed boats.

[3] This project was however cancelled as it "risked to result in commercial outputs", since some new technologies that Ullman had developed were shown to reduce shock exposure.

[4] Johan Ullman is, in 2013 responsible for ergonomics (human factors), and injury prevention at HSBO Pro, a group of experts in design and acquisition of high speed boats,[5] which also stages the HSBO Forum, a biannual international networking event for professionals in the high-speed work boat community.

[22][23] The case has also been subject to debates in the Swedish Parliament,[24][25] as well as in academic reports.
