Institute for Mathematics and its Applications
The primary mission of the IMA is to increase the impact of mathematics by fostering interdisciplinary research and linking mathematics and scientific and technological problems from other disciplines and industry.
The IMA hosts long-term visitors, funds postdoctoral research positions, and holds several conferences annually. The NSF has granted the IMA $19.5 million over the period 2005–2010, the largest single mathematics grant the NSF has ever awarded.  
Organization with similar names
Sharing a very similar name and the acronym IMA, it should not be confused with the Institute of Mathematics and its Applications, a professional body for mathematicians in the UK.
