Tom Moran received a PhD in experimental plasma physics at MIT, where he studied UV and visible light emitted by magnetically confined high temperature plasmas as part of a nuclear fusion research project. This led to work in visible and IR solar astronomy with Peter Foukal of Cambridge Research and Instrumentation, performing coronal and photospheric observations at the National Solar Observatory at Kitt Peak, AZ. and Sacramento Peak, NM. From there, he came to NASA/GSFC as an NRC fellow to work with Drake Deming and Don Jennings in IR solar astronomy, measuring magnetic field strengths as part of a project which is still active. Before the launch of SOHO, he joined the SUMER team to help calibrate and then operate the UV spectrograph, making coronal hole observations. He is now part of the STEREO team, and has worked to develop calibration procedures for coronagraph instrumental polarization. Out of that work, he became interested in studying the three-dimensional structure of CMEs using polarimetric measurements and developed a technique to reconstruct these eruptions, which he demonstrated using SOHO/LASCO observations. Polarimetric CME reconstruction continues to be one of his primary interests.
