Position/Title: Astrophysicist
Affiliation: NASA Marshall Space Flight Center
AAS Positions: AAS Nomination Committee member: 2019–present
Areas of Scientific Interest:
Studies of fundamental processes in the solar atmosphere leading to eruptive phenomena on a wide range of size scales. On the small-scale end are chromospheric spicules, which have lengths of ~5,000 km, and on the large-scale end are coronal mass ejections (CMEs), which can grow to be larger than the Sun’s diameter of 1.4 x 106 km.
Specific topics of research include:
- Theoretical and observations studies of solar spicules and other chromospheric features
- X-ray spectral observations of solar flares, including flare temperatures and coronal abundances
- Observational studies of solar eruptions, flares, and CMEs
- Observational and theoretical studies of X-ray, EUV, and UV solar jets
- Evolution of solar magnetic fields leading to solar eruptions
- Imaging of solar eclipses
Accomplishments:
- Over 100 refereed publications, about 50 of them as first author
- NASA Chief Planner for the Hinode satellite (2007–2013)
- Honorary Professor, University College London, Department of Space and Climate Physics (2003–2008)
- Participant in the movie Black Suns: An Astrophysics Adventure (2017)
