While in graduate school, Ken Cecire found that his greatest satisfaction was a teaching assistant in undergraduate introductory courses. Upon receiving an MA in Physics at City College, New York in 1981, Ken became a high school physics teacher. After several years of summer research at Jefferson Lab, Ken left the classroom in 1999 and moved to Hampton University to join the staff of the newly formed QuarkNet, a U.S. program to bring particle physics research to high school teachers and students. Ken was introduced to International Masterclasses during a visit to CERN in 2006.
