After working in the British National Coal Board and getting degrees in mining at the University of Leeds, Dave Summers went to what is now the Missouri University of Science and Technology (Missouri S&T, formerly the University of Missouri-Rolla) to lead a team to develop waterjet cutting and use. As a result, he was there when abrasive jets, hydro-demolition, hydroexcavation, and other now common uses were being developed. With recognition for the group becoming international and leading to several awards, Dave is also proud to have been one of the founding members of the WJTA.
