Dr. Andrea Thevis

I am a postdoc in the CRC 326 - GAUS in the reserach group of Prof. Martin Möller. I obtained my PhD from Saarland University under the supervision of Gabriela Weitze-Schmithüsen and Alice Niemeyer. My PhD thesis is available here. I am a member of the Integrated Research Training Group of the SFB-TRR 195. My research was funded by the SFB-TRR 195 Symbolic Tools in Mathematics and their Application and the German Academic Scholarship Foundation.

My primary research interests are in geometry and group theory. I like thinking about questions that connect a geometric setting with group theory. At the moment, I am mainly working with translation surfaces (in particular square-tiled surfaces).

  • stand of the math department at the Open House.

As a mentor in the program MentoMINT, I supported female high school students interested in math and sciences when choosing their field of study after high school.
