Dr. Allen's research focuses on the intersection of X-ray astronomy and cosmology, with particular expertise in galaxy clusters, dark matter, dark energy, and black hole physics. His work bridges observational data with theoretical models to understand the large-scale structure of the universe. The XOC group under his leadership develops cutting-edge instrumentation for future X-ray missions while conducting observational studies of cosmic phenomena. His research program spans multiple wavelengths including X-ray, optical, mm-wave, and radio astronomy, with strong emphasis on gravitational lensing and statistical methods in data analysis.
Analysis of Dr. Allen's recent publications reveals a consistent focus on galaxy cluster dynamics, X-ray detector development, and dark energy studies. His work combines observational data from major facilities like Chandra, XMM-Newton, and the James Webb Space Telescope with theoretical models to address fundamental questions in cosmology. A significant portion of his recent work focuses on developing next-generation X-ray detector technology, particularly the SiSeRO devices that enable single-electron sensitivity for future space missions.

Professor Allen maintains an active advising program with numerous doctoral students and postdoctoral researchers. His leadership extends to major collaborations including the Dark Energy Survey, CMB-S4, and the development of future X-ray missions like Athena and AXIS. His research group receives substantial funding from DOE, NASA, and NSF for both observational programs and detector development work. The XOC group operates a dedicated X-ray beamline for detector testing and calibration, supporting their instrument development efforts.
The X-ray Astronomy and Observational Cosmology (XOC) group led by Professor Allen comprises faculty, postdocs, graduate students, and research staff working on both observational programs and detector development. The group collaborates extensively with SLAC National Accelerator Laboratory and international partners on major projects including the Vera Rubin Observatory's Legacy Survey of Space and Time (LSST), the Simons Observatory, and future X-ray missions. Their detector development work focuses on the SiSeRO technology for next-generation X-ray astronomy missions.
