The Institute for Theoretical Atomic, Molecular and Optical Physics (ITAMP) was established in 1988 to attract and encourage talented graduate students to enter this field of research, which emphasizes theoretical study of fundamental questions in atomic and molecular physics. ITAMP hosts many visitors, both long- and short-term, and conducts numerous conferences and workshops annually.
The Institute for Theory and Computation, also hosted by the CfA, is dedicated to research in high-end astrophysical computing. One of the primary objectives is to integrate conceptual theory with computational modeling. The ITC consists of members of the Harvard Department of Astronomy, Smithsonian astrophysicists, postdoctoral researchers, graduate students, and associates at other institutions.
