Marcel Demarteau

Division Director

Marcel Demarteau is the Division Director of the Physics Division at Oak Ridge National Laboratory. In this role he leads a broad research program spanning studies of nature at its most fundamental level to the application of advanced detection technologies for national security. The Division hosts the LEGEND experiment that searches for neutrino-less double-beta-decay in Ge-76, for which ORNL is the lead laboratory. Two unique neutrino experiments are run out of the Division, the COHERENT experiment at the SNS currently the only experiment that has observed coherent elastic neutrino nucleus scattering, and the PROSPECT experiment at the High Flux Isotope Reactor, the only reactor-based neutrino experiment in the country. Strong collaborative research programs are run at FRIB at Michigan State University and with the CMS and ALICE experiments at the the Large Hadron Collider at CERN. A fundamental neutron physics beamline is managed and operated by the Division dedicated to research in fundamental neutron physics, nuclear physics, and particle physics. The theory program is world-leading in computational simulations of core-collapse supernovae, neutron star mergers and nuclear structure calculations. An applied physics research program complements the science program with unique non-destructive neutron and gamma-ray imaging techniques for nuclear non-proliferation and national security.

Research Interests 

Marcel Demarteau has done particle physics research at many different particle colliders with a focus on electroweak physics processes. He is pioneering the frontiers of particle and nuclear physics, exploring the mysteries of the universe through high-energy particle colliders and low-energy fundamental physics experiments.  

With the exciting promise of quantum sensors and quantum technologies, Marcel Demarteau is leading the charge in quantum sensors for particle physics as a co-founder of the innovative Quantum Sensor and Emerging Technologies Collaboration at CERN. This forward-thinking initiative aims to introduce a new paradigm for detector technologies to understand particle interactions and open new pathways to discovery.

Currently, Marcel Demarteau's research focus includes the ambitious search for neutrinoless double beta decay using germanium, as part of the prestigious LEGEND experiment, spearheaded by the ORNL Physics Division. 

He is also engaged in articulating the vision for a future Higgs Factory, a monumental project that could provide unprecedented insights into the fundamental building blocks of nature.
