The Murchison Widefield Array (MWA) is an 8,000-antenna, 80-300 MHz, imaging radio array under construction in Western Australia. MWA is composed of hundreds of "tiles", which are 4 by 4 arrays of dipole antennas. Some of the key performance features of MWA are a large field of view (up to 50 degrees), high sensitivity (11,000 square meters of collecting area at 150 MHz), and accurate real-time polarization and intensity calibration. Key science projects of the MWA are understanding structure in the early universe through the detection of the Epoch of Reionization and remote imaging of magnetic and density structure in the solar corona and inner heliosphere. The performance required to meet the goal of our solar and cosmology science goals also makes MWA well-suited for blind searches for astrophysical radio transients.

I am a member of the Solar, Heliospheric, and Ionospheric (SHI) science consortium for MWA. I am interested in using Faraday Rotation as a remote means of determining the magnetic field of the corona, solar wind, and corona mass ejections (CMEs). I am also interested in using MWA to look at solar radio bursts and to study the ionosphere. Last year I was vice-chair of the SHI consortium, and this year I am serving as chair. I am also chair of the overall MWA Science Council.
