P. Di Stefano

P. Di Stefano is a Professor at Queen's University in the Department of Physics, Engineering Physics & Astronomy, where he has held faculty positions since 2009. He was promoted to Professor in 2018 after serving as Associate Professor (2009-2018). His career includes junior faculty positions at Université Lyon 1 (2001-2009), postdoctoral research at the Max Planck Institute for Physics in Munich (1998-2001), and he earned his PhD from Université Paris Sud Orsay and CEA Saclay in 1998.

Research Focus

Di Stefano's research specializes in rare-event physics and advanced detector development. His primary areas include:

• Dark matter detection through experiments like DEAP/DarkSide/Argo at SNOLAB
• Cryogenic instrumentation for particle physics applications
• Nuclear decay studies including the KDK potassium decay experiment
• Low-temperature scintillation materials for particle detectors

His publication trends (2018-2025) demonstrate deep involvement in dark matter experiment design, particularly focusing on cryogenic detector technologies, liquid argon systems, and background suppression techniques. Recent work emphasizes quality assurance for DarkSide-20k components and precision measurements of nuclear decay parameters.

Research Operations

Di Stefano leads active research programs at SNOLAB, one of the world's deepest underground laboratories. His group seeks graduate students and research staff for projects involving:

• DEAP/DarkSide/Argo dark matter experiments
• KDK potassium decay measurements
• Cryogenic detector development

He emphasizes direct engagement with experimental work at underground facilities and maintains collaborations across Europe and North America.
