He studied under Heinrich Behnke at the University of Münster and received his doctoral degree in 1931 at the age of 23.
He is noted for work on several complex variables. He obtained a subsequent research fellowship with Professor Francesco Severi in Rome to explore how algebraic geometry could be integrated into the theory of functions of several complex variables. In 1952 he left Latin America for Switzerland where he worked at the International Labour Organization.
After he retired from the International Labor Organization he went on to teach at the University of Fribourg.
He considered returning to Germany at times, but had difficulty securing a position and regaining German citizenship.
Peter Thullen was an enthusiastic Wandervogel and active in the Catholic youth movement and opposed the rise of Nazism. He would later disapprove of the post-war regime of Konrad Adenauer as he felt it retained some of the "ills" of German nationalism.
