We explore & discover

Scientists at the Department of Terrestrial Magnetism (DTM) bring the perspective of several disciplines to broad questions about nature. DTM's name comes from its original role to chart the Earth's magnetic field. This goal was largely accomplished by 1929. Since then, DTM has evolved to reflect the growing multi-disciplinary nature of the Earth, planetary, and astronomical sciences. Today, the historic goal remains to understand the physical Earth and the universe that is our home.

Carnegie Science President Matthew Scott: In Celebration of National Postdoc Week

National Postdoc Week

Postdoctoral fellows are the lifeblood of Carnegie Science. Unlike many research establishments, where postdocs work in a hierarchy, Carnegie postdocs work alongside senior scientists collaborating and contributing equally, while also being mentored. They are truly the core workforce. They participate fully in the institution’s vigorous intellectual life, and have complete access to the laboratory instruments and facilities. We give to them, but they give back many times over. Being a postdoc at Carnegie is, indeed, special. They enhance the Carnegie mission of unfettered, imaginative scientific research and they expand Carnegie’s influence all over the world and into the next generations. They are the seed corn for scientific achievement. We honor them today in celebration of National Postdoc Appreciation Week
