The start of the new year will bring a new president and CEO to COSI.

The science center announced Nov. 10 it has tapped Frederic Bertley as its new leader. Bertley, who starts Jan. 1, has been senior vice president for science and education at the Franklin Institute in Philadelphia (the Keystone State's most visited museum) since 2008.

Bertley will become COSI's fifth president when he takes over for the retiring David Chesebrough, who has held the role since April 2006. Chesebrough has been widely credited with bringing in innovative exhibits and making other strategic moves to reverse attendance declines that followed the facility's move to the old Central High School.

In Philadelphia, according to COSI's announcement, Bertley focused on STEM initiatives and improving science education, and co-founded the award-winning Philadelphia Science Festival, a nine-day community event.

Bertley has a Ph.D. in immunology and a bachelor's degree in physiology and mathematics from McGill University in Montreal.
