Christian Haffner

Christian Haffner is a Visiting Research Fellow in the Microsystems and Nanotechnology Division of PML at NIST, Gaithersburg in the field of integrated quantum technologies. He received his Ph.D degree from ETH Zurich in 2018, for which he was awarded the ETH Medal and Hans-Eggenberger Prize. During his PhD, he focused on innovating novel active electro-optic plasmonic devices in the group of Juerg Leuthold. He obtained his B.Sc. and M.Sc. degree in electrical engineering from the Karlsruhe Institute of Technology (Germany) in 2012 and in 2013, respectively. He was ranked first in his master batch. During his study, he was a scholarship holder of the German National Academic Foundation, which provides support to the top 0.5% of the German student population. His research has been published in high-impact journals including Nature, Nature Photonics, Science and Nano Letters. News outlets such the OSA’s Optics and Photonics News and the IEEE Spectrum have featured his publications.
