Also  looking at his https://academic.microsoft.com/author/2717311145 MA profile I do see many publications but few with a strong impact as per analysis above (already the 5th paper has  28 citations only and a total  of 220 papers are listed for the subject but  an h-index of 17 speaks to a  lower  number of quality papers). I cannot see the argument here for #1. Even the most cited paper Colao et al on double pulse  LIBS is included as a listing in a review of LIBS as a  key paper but not singled out, so probably not truly a landmark paper: "Fortunately, several very informative reviews and key papers have been written by leading groups in this field double pulse LIBS, in addition to a few modeling papers (see, for example, Babushok et al., 22 Noll et al., 307 Scaffidi et al., 325 Mao et al., 317 Colao et al., 301 Corsi et al., 306 Piñon and Anglos, 335 De Giacomo et al., 26,333 Bogaerts et al., 165 and Rai et al. 167
