Candidate Statement:

The AAS is an extraordinary professional organization, one that not only provides comprehensive services to its members, but one that is exercising leadership in ensuring that access, diversity, and inclusion are front and center in its thinking about the wider astronomy and astrophysics enterprise. It has, moreover, been proactive in developing a robust ethics and anti-harassment policy so that its professional gatherings are safe and productive. The AAS has also shown considerable vision in positioning its suite of premier journals for a successful future. It’s been my privilege to have served as Chair of the Publications Committee, participating in the development of a strategic plan and overseeing elements of its implementation. Still, while the AAS has enjoyed real success, it faces ongoing and inter-related challenges — in making the promise of diversity and inclusion a reality, in providing support and tools for its education mission, in bringing its varied membership together for scientific workshops and meetings, in its advocacy for astronomy and astrophysics to government policy makers, and in providing a premier suite of scientific journals to the wider community. I would be honored to serve as a Trustee, changing my focus from AAS Publications to the wider AAS mission and the many challenges that lie ahead.
