He earned his Ph.D. in 1966 at the Technical University of Munich and joined the faculty there in 1973. He is the author (with Josef Stoer) of "Introduction to Numerical Analysis", a standard reference for the theory of numerical methods, and has also authored numerous other books and articles. The book "From Nano to Space: Applied Mathematics Inspired by Roland Bulirsch" is a tribute to his work. The Bulirsch–Stoer algorithm is named after him and Stoer.
