A warm welcome to Ester Carranza Botey, who is joining our group here in Innsbruck as a guest for seven months. Ester completed her master studies in physics and physical technologies at the University of Zaragoza, Spain. For her master thesis and for an optics research internship during her master studies, she worked in the field of photonics and nanostructured technologies. Now, Ester will start designing the new dysprosium tweezer experiment of our group that will be located at DIPC in Donostia/San Sebastian, Spain.
