From 1970 to 1978 she was assistant professor (1970 Assistant Professor, 1974 Associate Professor ) and since 1978 Associate Professor of Molecular Biophysics and Biochemistry at Yale University in New Haven, Connecticut - interrupted by stays abroad at the Medical Research Council Laboratory of Molecular Biology and the Max Planck Institute for Biophysical Chemistry in Göttingen, Germany, and a research fellowship at the California Institute of Technology (Caltech ) in Pasadena, California.

Joan A. Steitz Thomas A. Steitz is married to who in 2009 received the Nobel Prize for Chemistry. The couple has a son.


Steitz was a pioneer in the field of RNA research. Discovered the snRNP complexes and their function in connection with the removal of non-coding portions of the pre-mRNA and the joining of coding portions ( splicing ). Recent work dealing with the effect of regulatory RNA of different viruses on genetic material of the host cell.
