Available Postdoc Position

Solar and Heliospheric Observations and Models
A postdoctoral research associate position is available for analysis of solar and heliospheric observations with emphasis on connecting solar observations to their signatures in the in situ data. Various techniques are available to make this connection, including the use of both empirical and 3D magnetohydrodynamic models. Of particular interest is interpretation of imaging and in situ data from the STEREO mission.
