Thomas A. Steitz receives a Ph.D. in biochemistry and molecular biology from Harvard University. There, he works under the direction of the 1976 Nobel Laureate in Chemistry William N. Lipscomb Jr. determining the structure of the molecule methyl ethylene phosphate. Steitz is also part of the Lipscomb's researching group, which determines the atomic structure of carboxypeptidase A and aspartate carbamoyltransferase, the largest atomic structures determined until then.

Thomas A. Steitz is Investigator at Howard Hughes Medical Institute.

Thomas A. Steitz is Visiting Professor at the University of Colorado in Boulder.

Thomas A. Steitz is a Macy Fellow at the University of Göttingen.

Thomas A. Steitz receives the Nobel Prize in Chemistry "for studies of the structure and function of the ribosome," along with Venkatraman Ramakrishnan and Ada E. Yonath.

Thomas A. Steitz works as Sterling Professor of Molecular Biophysics and Biochemistry at Yale University. During the 1970s, he begins his structural studies of yeast hexokinase captured with and without the substrate glucose bound, a project that occupies the efforts of most of his laboratory at the Howard Hughes Medical Institute.

Thomas A. Steitz pursues a Postdoctoral Research as a Jane Coffin Childs Postdoctoral Fellow at MRC Laboratory of Molecular Biology at Cambridge University in the group of David Blow. Here, he collaborates with Richard Henderson on determining the structure of chymotrypsin complexes with substrates.

The group of researchers headed by Thomas A. Steitz determines the structure of the 50S ribosomal subunit in Steitz's own laboratory at Yale University. This is the discovery that gains him the Nobel Prize in 2009.

Thomas A. Steitz studies chemistry as an undergraduate at Lawrence University. During this period, he is a member of the fraternity Delta Tau Delta. He has many inspiring teachers, but the person who has the greatest influence on Steitz to pursue a career in science and, in particular, chemistry is Professor Robert Rosenberg.

Thomas A. Steitz is a Fairchild Scholar at California Institute of Technology.

Thomas A. Steitz is born in Milwaukee, Wisconsin.
