Summary
Tom Woods joined LASP in 1987. He serves as a bridge between the science disciplines and the Engineering and Mission Operations & Data Systems Divisions at LASP, helping to convey the interests and perspective of each group to the other. Tom is also the chair of the Proposal Development Committee (PDC) that helps to guide and review LASP’s proposals and for LASP’s Internal Research and Development (IRD) program. His research focuses on the solar ultraviolet irradiance and its effects on Earth’s atmosphere and climate.
