Diane McKnight is an Associate Professor of Environmental Engineering at the University of Colorado, Boulder.

Dr. McKnight will show images from Antarctica, including Cape Royds and the Dry Valleys which were explored by Scott and Shackleton, and discuss her research on ecosystem responses to the interacting effects of the ozone hole and climate change.  She will also be signing copies of her children’s book, The Lost Seal, which describes the first documented encounter with a live seal in the remote McMurdo Dry Valleys of Antarctica.
