Francesco Piastra obtained his PhD in Physics in this group in 2017, primarily working on XENON100 and XENON1T experiments. His research activity focussed on low-background techniques and high-accuracy measurements of LXe response with a Xurich-II detector. In 2018, he moved to LHEP at the University of Bern  as a postdoctoral fellow to work on the DUNE experiment, mainly involved in the R&D and in the development of the simulations software of the ArgonCube demonstrator. In 2022 he worked as an R&D scientist at IRsweep,working on quantum cascade lasers. In 2023 he enthusiastically came back to work in our group as a technical lead to support the group on DARWIN, XENON and LEGEND-1000 experiments. His other interests and hobbies include reading, jazz, hiking, cooking, advanced electronics, and playing chess.
