Nicholeen Viall

Nicholeen Viall is an American solar physicist who is the Chair of the American Astronomical Society's Solar Physics Division. Viall is known for her work on connecting dynamics of the solar corona to dynamics of the solar wind, based on observed variability of the corona-heliosphere system with both remote-sensing instruments and in-situ probes, and for her work on understanding evolution of the plasma in the inner heliosphere. She is the mission scientist for NASA's PUNCH mission, and a co-investigator on the ISS/CODEX and Parker Solar Probe/WISPR coronal imaging instruments.

Education
Viall graduated from the University of Washington in 2004 with a Bachelors of Science in Astronomy and Physics. She received her Master of Arts in Astronomy at Boston University in 2007 and PhD in 2010. She is a graduate of Kentwood High School.
