I’m a masters student in Bioinformatics at the Technical University of Munich and Ludwig-Maximilians-Universität München since October 2020. I developed a federated Cox proportional hazard model app for the FeatureCloud platform for my bachelor thesis. Recently, I have worked with cytometry data and built CYANUS - CYtometry ANalysis Using Shiny - a user-friendly R Shiny App allowing the user to analyze cytometry data. Currently, I am working as a HiWi at CoSy.Bio.
