It has truly been a pleasure working with all of you.

This is also marks the end of my term as Chair of GISS. It has been a pleasure serving this community and I feel we accomplished many important things including modernizing the constitution (which was last modified in 1988). I want to extend a special thanks to Zachary Christman for his dedication both as a chair but particularly as the chair emeritus who worked along side me through the last 2 years. His contributions, guidance, and encouragement were indispensable. I look forward to working alongside Dr. Kar in her term as Chair as she moves GISS forward over the coming years.

Thanks for your service and collaboration, and I am always glad to continue to offer guidance and support in the years ahead.
