Dr. Henrique Araujo

Biography

Henrique Araujo is an experimental astroparticle physicist at Imperial College London, contributing to the Particle Physics group. He is a Senior Research Scientist in the Particle Physics Department at STFC Rutherford Appleton Laboratory. His research primarily focuses on the direct detection of dark matter, an elusive substance thought to make up a significant mass of the universe. Araujo's work involves large physics experiments located deep underground that attempt to detect the faint and rare collisions of dark matter particles with ordinary atoms using sensitive radiation detectors. He leads substantial UK teams that contribute to next-generation experiments that utilize liquid xenon technology, such as the LUX-ZEPLIN (LZ) experiment. He has been involved with the ZEPLIN dark matter search at the Boulby Underground Laboratory for over a decade, where he has contributed to the development and application of two-phase xenon technology for dark matter searches. Araujo has held pivotal roles in many significant collaborations, including serving as a data analysis coordinator for ZEPLIN-III and a spokesperson for the collaboration starting in 2010. Since joining the LUX experiment in 2012, he has overseen world-leading dark matter searches. The LZ experiment is set to operate until 2028, continuing to probe various models of particle dark matter. Araujo also leads a large team across 14 UK institutes that are developing contributions to the upcoming XLZD Rare Event Observatory for dark matter and neutrino physics.
