Leo Sack

Public Programs Assistant

I manage Adelson Library, which is a branch of the Cornell University Library system and also open to the public as part of the Cornell Lab’s Visitor Center. In addition, I coordinate and lead Kids Discover the Trail! school field trip programs for most of the 5th grade classes in Tompkins County, in partnership with the Discovery Trail. I can also be found leading behind-the-scenes tours and other public programs, providing live-streaming video of guest lectures, assisting with the Front Desk, and answering visitors’ many questions. As part of the “public face” of the Lab, I am here to facilitate positive experiences for all of our library users and Lab visitors.

Before joining the Lab, I spent 15 years presenting environmental education and natural science education programs at parks and museums in Ohio and Colorado. Over and over again, I’ve seen how activities like birding can empower people to explore and discover the natural world for themselves. Today, I take every opportunity to introduce visitors to Lab resources like Merlin and eBird, and encourage them to explore further.

Beyond the Lab

I am obsessed with empowering others to explore the natural world for themselves. At the Lab, you’ll never see me more excited than when I’m helping a beginning birder learn how to use binoculars, a spotting scope, a field guide, or an app. Outside the Lab, you’ll find me hosting hands-on stargazes and teaching aspiring astronomers how to read star charts and point telescopes at the night sky.
