She is investigating the properties of fiber Bragg gratings, mirrors, and oscillators introduced into the fiber, and how they accommodate different degrees of freedom of seismic signals. In a side project together with the University of Hamburg, Wanda has also set up a homodyne quadrature interferometer to investigate the quality and resonance frequency changes of a suspended test mass in the presence of temperature gradients. Additionally, she supports the <a href=\"http:\/\/wave-hamburg.eu\" rel='nofollow'>WAVE<\/a> team and especially the outreach acitivities also in <a href=\"https:\/\/www.instagram.com\/wave.hamburg\/\" rel='nofollow'>social media<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Holstenhofweg 85, 22043 Hamburg<br>Geb\u00e4ude H02 &#8211; 2807<\/p>\n<\/div>\n<\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:20%\">\n<figure class=\"wp-block-image size-large is-style-default\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/www.hsu-hh.de\/mt\/wp-content\/uploads\/sites\/868\/2024\/09\/Image-1-1024x1024.jpeg\" data-credit=\"Spiridon Beis\" alt=\"\" class=\"wp-image-1456\" srcset=\"https:\/\/www.hsu-hh.de\/mt\/wp-content\/uploads\/sites\/868\/2024\/09\/Image-1-1024x1024.jpeg 1024w, https:\/\/www.hsu-hh.de\/mt\/wp-content\/uploads\/sites\/868\/2024\/09\/Image-1-300x300.jpeg 300w, https:\/\/www.hsu-hh.de\/mt\/wp-content\/uploads\/sites\/868\/2024\/09\/Image-1-150x150.jpeg 150w, https:\/\/www.hsu-hh.de\/mt\/wp-content\/uploads\/sites\/868\/2024\/09\/Image-1-768x768.jpeg 768w, https:\/\/www.hsu-hh.de\/mt\/wp-content\/uploads\/sites\/868\/2024\/09\/Image-1-100x100.jpeg 100w, https:\/\/www.hsu-hh.de\/mt\/wp-content\/uploads\/sites\/868\/2024\/09\/Image-1-1100x1100.jpeg 1100w, https:\/\/www.hsu-hh.de\/mt\/wp-content\/uploads\/sites\/868\/2024\/09\/Image-1.jpeg 1198w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<h2 class=\"wp-block-heading\">Spiridon Beis (student assistant)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Spiridon is studying physics in Aachen.
