Mock became interested in injury prevention in the late 1980s when he worked as a surgeon in Ghana. He has served as chair of the Association for the Advancement of Automotive Medicine’s Task Force on Expanding International Relations and he’s a member of the advisory board of the Association for Safe International Road Travel.

Each year Mock spends several months in developing nations where many injuries remain undocumented. In some cases deaths are not reported or the injured do not seek medical attention. This number reaches 49 percent in some of the surveyed rural areas. Mock’s research incorporates community-based surveys that include direct household visits and interviews. According to his analysis, deaths in a prehospital setting increased as a nation’s socio-economic level decreased. This research has been instrumental in developing and implementing low-tech and sustainable programs to establish or improve pre-hospital trauma care in these countries.

Mock’s continuing work at Harborview includes a U.S. study of the effectiveness of various safety features in vehicle design. He continues to donate his time and expertise to preventing and reducing deaths and disabilities on national and international levels.
