Ryan MacLellan

Ryan MacLellan is an Assistant Professor in the Department of Physics and Astronomy at the University of Kentucky. His experimental nuclear physics research focuses on neutrinoless double-beta decay searches using advanced xenon-based detectors.

MacLellan's research encompasses:

• Ultra-low background detection technologies
• Double-beta decay physics
• Single-atom imaging techniques
• Neutrino interaction studies
• Dark matter searches

Recent publications demonstrate leadership in nEXO experiment development, including novel barium tagging methods using solid xenon matrices, radon assay systems, and scintillation signal simulation using generative adversarial networks. His work significantly advances detector technologies for next-generation rare-event searches.

No specific awards or student mentoring relationships are documented in available sources.

MacLellan is a key contributor to major collaborations including nEXO and EXO-200, focusing on detector design, calibration, and background reduction strategies.
