von Friesen became a professor at the Department of Physics at Lund University in 1948, and held the post until his retirement in 1972 when was succeeded by Hans Ryde. As a professor he continued his research on nuclear physics, and he was in charge when Lund University received its first particle accelerator. One of the highlights of his research happened when he and his team could show that the presence of elements in the Milky Way is the same as it is in the distant galaxies.
For a wider public, he became known through his participation in the TV program Fråga Lund in the 1960s and 1970s, where he was one of six scientists in the Panel who answered questions from the audience.
