Dr. Andreas Jechow is an interdisciplinary physicist with a broad expertise in photonics, the science of light. Earlier in his career Andreas worked in laser physics and quantum optics, for example on imaging the "shadow of a single atom" with lasers. In 2015, Andreas transitioned to environmental sciences where he applies his knowledge of light in research on light pollution.  Some of the fascinating studies Andreas is involved in include the impact of light on bats and insects and also on aquatic ecosystems. You’ll love the story of his daughter’s astute observation of the moon, and you’ll be jealous to hear that the city of Berlin where he lives is one of the darkest cities in Europe.
