Candidate Statement: The AAS is vital for US astronomy. It’s a privilege, and an obligation, to share the natural excitement and the relevance of our field with a wider audience — and it’s necessary for the long-term health of our community. My goal as Councilor will be to insure that the Society continues to be a resource to the professional astronomy community, through its meetings and publication support, and to engage the general public, amateur astronomers and teachers.

Our community faces some tough issues, such as the low selection rates of proposals to NSF and NASA, and the prospects for academic employment of astronomers just starting their professional careers. The AAS should continue work toward solutions with government agencies and the various national committees that set policy and priorities for our field. 

My scientific and professional experience is broad, having worked in academia and a government laboratory. I've written many observing and research proposals so I understand the pressures that proposers face. As a reviewer I’ve faced the challenge of allocating scarce resources fairly and effectively. As an organizer of many workshops and conferences, I appreciate the very diverse interests of AAS members. As Councilor, I will listen to the membership's views and concerns and I will represent your interests.
