The Harvard-Smithsonian Center for Astrophysics is inviting applications for Postdoctoral Research Positions at the Institute for Theory and Computation (ITC). One of the primary objectives of the ITC is to integrate conceptual theory with computational modeling. Interested candidates working in any field related to theoretical and/or numerical astrophysics are encouraged to apply. The positions are for two years, and renewable for a third year, contingent on performance and funding. The fellowship includes a stipend of $63,000 a year plus health insurance and additional benefits.
