Lukas Retschmeier

I am a second-year PhD student at Providentia at BARC at the University of Copenhagen under the supervision of Rasmus Pagh. My research area is that of Differential Privacy currently working on private graph algorithms with applications to private synthetic data generation.

Before that, I worked as a PLM consultant for Atos in my vibrant home city, Munich. I am proficient with various technologies and tools, including Java with the Spring Framework, AngularJS, Siemens Teamcenter, and Docker. Furthermore, I supported various tender offerings from a technical side and gained a lot of experience in supervising interns. For a detailed overview of my projects, have a look at my CV.

In my spare time, you can find me playing (beach) volleyball or sitting in front of my piano playing sonatas.
