Rachid Nouicer

Dr. Nouicer is a distinguished experimental physicist at Brookhaven National Laboratory (BNL) whose career has been closely associated with the Relativistic Heavy Ion Collider (RHIC) since the program’s inception. Since 1998, he has made sustained and consequential contributions to three major RHIC collaborations: PHOBOS (1998–2006), PHENIX (2006–2016), and sPHENIX (2016–2026).

Over more than 25 years, Dr. Nouicer has combined scientific leadership with expertise in precision instrumentation and data-driven physics. His contributions encompass the design, construction, commissioning, and operation of silicon semiconductor particle-tracking detectors, as well as the rigorous analysis and interpretation of heavy-ion collision data. This work requires a close integration of detector performance, data quality, and physics analysis—an integration that has been central to the success of RHIC’s experimental program.

Dr. Nouicer’s research has included particle-multiplicity-density and heavy-quark measurements in the PHOBOS and PHENIX experiments. These studies contributed to the experimental evidence that established the quark–gluon plasma, a state of strongly interacting matter created under extreme conditions. He has also contributed to the dissemination of RHIC science through a substantial record of peer-reviewed publications. His broad experience—from detector development and experimental operations to physics analysis and interpretation—continues to support the evolving scientific mission of sPHENIX.

In recognition of his accomplishments, Dr. Nouicer was elected a Fellow of the American Physical Society in 2017. His APS citation states: “For his role in the discovery of the Quark Gluon Plasma at the Relativistic Heavy Ion Collider, using particle multiplicity density and heavy quark measurements in the PHOBOS and PHENIX detectors, with leading contributions to the silicon tracker design, construction, and operation and data analyses.”
