Marzio Nessi received his undergraduate and graduate education at ETH Zurich, studying mathematics and physics. After obtaining his Ph.D. degree and a short period as a postdoctoral research scientist at ETH, working on medium energy physics and accelerator-based mass spectrometry, he moved to Rice University in Houston, USA. There, he changed the focus of his research towards experimental particle physics. During his time in the US, Nessi participated in experiments at Brookhaven National Laboratory, Fermilab, Los Alamos and CERN.
In 1989, he transferred to CERN as a research fellow, becoming a staff physicist soon after. Since then, he has been involved in various experiments. He took part in the UA2 experiment and was spokesman of the RD34 project.
Marzio Nessi contributed to the ATLAS experiment from its beginning on. He was a founder and later project leader of the ATLAS tile calorimeter as well as overall ATLAS technical coordinator. He served as ATLAS project manager from 2000 until 2013, when the Higgs boson was discovered.
Since 2011 he has been a titular professor in the physics department of the University of Geneva, and for ten years he has been the general coordinator of the CERN Neutrino Platform (CENF), which he founded in 2012. [1]
Since April 2014, he is the Scientific Director of the Journal of Instrumentation.
In 2014 he co-founded the CERN IdeaSquare innovation platform, [2] [3] which became the basis of the European Union ATTRACT programme and the GRADE research programme. [4]
Since the beginning of the LBNF/DUNE research programme, Marzio Nessi became involved in the US neutrino program. This meant first rebuilding at CERN the ICARUS detector and installing it at Fermilab, then participating in the SBND [5] Fermilab experiment, leading the Liquid Argon membrane cryostat and cryogenics construction.
In 2020 he has been asked by the Italian INFN president to become the construction director for the experiment DARKSIDE-20K at LNGS.
Since the creation of the LBNF/DUNE neutrino programme in 2014, Marzio Nessi took a leading role in the definition and R&D of the far detectors, promoting and supporting the concept of protoDUNE, [6] which has given a strong realistic basis to the entire neutrino US program. In 2017 he took the leadership in defining all integration and installation activities of the LBNF/DUNE far detectors.
In 2019 he was appointed Deputy Project Director of LBNF/DUNE, responsible for all activities related to the far detectors and cryogenics, a US-Fermilab role that he is still fulfilling at present.
Fermi National Accelerator Laboratory (Fermilab), located just outside Batavia, Illinois, near Chicago, is a United States Department of Energy national laboratory specializing in high-energy particle physics. Since 2007, Fermilab has been operated by the Fermi Research Alliance (FRA), a joint venture of the University of Chicago, and the Universities Research Association (URA); although in 2023, the Department of Energy (DOE) opened bidding for a new contractor due to concerns about the FRA performance. Fermilab is a part of the Illinois Technology and Research Corridor.
ATLAS is the largest general-purpose particle detector experiment at the Large Hadron Collider (LHC), a particle accelerator at CERN in Switzerland. The experiment is designed to take advantage of the unprecedented energy available at the LHC and observe phenomena that involve highly massive particles which were not observable using earlier lower-energy accelerators. ATLAS was one of the two LHC experiments involved in the discovery of the Higgs boson in July 2012. It was also designed to search for evidence of theories of particle physics beyond the Standard Model.
ROOT is an object-oriented computer program and library developed by CERN. It was originally designed for particle physics data analysis and contains several features specific to the field, but it is also used in other applications such as astronomy and data mining. The latest minor release is 6.28, as of 2023-02-03.
The UA1 experiment was a high-energy physics experiment that ran at CERN's Proton-Antiproton Collider, a modification of the one-beam Super Proton Synchrotron (SPS). The data was recorded between 1981 and 1990. The joint discovery of the W and Z bosons by this experiment and the UA2 experiment in 1983 led to the Nobel Prize for physics being awarded to Carlo Rubbia and Simon van der Meer in 1984. Peter Kalmus and John Dowell, from the UK groups working on the project, were jointly awarded the 1988 Rutherford Medal and Prize from the Institute of Physics for their outstanding roles in the discovery of the W and Z particles.

In 2011, the OPERA experiment mistakenly observed neutrinos appearing to travel faster than light. Even before the source of the error was discovered, the result was considered anomalous because speeds higher than that of light in vacuum are generally thought to violate special relativity, a cornerstone of the modern understanding of physics for over a century.
The Deep Underground Neutrino Experiment (DUNE) is a neutrino experiment under construction, with a near detector at Fermilab and a far detector at the Sanford Underground Research Facility that will observe neutrinos produced at Fermilab. An intense beam of trillions of neutrinos from the production facility at Fermilab will be sent over a distance of 1,300 kilometers (810 mi) with the goal of understanding the role of neutrinos in the universe. More than 1,000 collaborators work on the project. The experiment is designed for a 20-year period of data collection.
ICARUS is a physics experiment aimed at studying neutrinos. It was located at the Laboratori Nazionali del Gran Sasso (LNGS) where it started operations in 2010. After completion of its operations there, it was refurbished at CERN for re-use at Fermilab, in the same neutrino beam as the MiniBooNE, MicroBooNE and Short Baseline Near Detector (SBND) experiments. The ICARUS detector was then taken apart for transport and reassembled at Fermilab, where data collection is expected to begin in fall 2021.
The Particle Physics Project Prioritization Panel (P5) is a scientific advisory panel tasked with recommending plans for U.S. investment in particle physics research over the next ten years, on the basis of various funding scenarios.
