In January 2015, my students and I travelled to Nepal to build a library, teach classes, and design a ceramic water filtration system for the underprivileged children at the Maya Universe School. “A Return to Maya” is a documentary on the trip. The film premiers Thursday, April 23, at Colby-Sawyer College. The showing will take place at 5:00 pm in the Wesson Honors Suite in Colgate Hall.
