My research interest is to explore applications of optical microcavities in the fields of solid state quantum optics, optical sensing, microscopy, spectroscopy, and optomechanics. One of the central goals of my research group is to enhance light-matter interactions to realize efficient light-matter interfaces at the single quantum level, and to enable novel schemes for spectroscopy and sensing. We employ and further develop fiber-based Fabry-Perot microcavities, which combine microscopic mode volumes with exceptionally high quality factors, and at the same time offer open access for a variety of samples
