Background And Education
Professional Biography
- Senior astrophysicist at the Harvard-Smithsonian Center for Astrophysics, primarily working in high-energy astrophysics. I am involved with multiple X-ray observatories, and try to maintain a broad perspective regarding science priorities in astrophysics and their impact on mission requirements and capabilities. My research focuses on processes in the interstellar medium and on maintaining an atomic database (AtomDB) that is used throughout the field to model the spectra of hot collisional plasmas.
