Meierfrankenfeld received his doctorate in 1986 from the University of Bielefeld under Bernd Stellmacher ( A solution to the pushing-up problem for a class of finite groups ). He has been a professor at Michigan State University since the early 1990s .

Meierfrankenfeld is involved with Gernot Stroth , Stellmacher and others in the program to simplify the classification of finite simple groups , after Daniel Gorenstein had already led the first such simplification program in the 1980s .

In 1989, together with Robert Griess and Yoav Segev , he proved the uniqueness of the monster , the largest sporadic finite simple group that Griess first constructed.
