Cook acts as the defensive coordinator and works with the center draw unit. She also has input into every phase of the game and operation, including recruiting, scouting, player development, film breakdown and program management.

In her first season at Princeton, in 2013, Cook helped guide the team to its 21st NCAA Tournament appearance. The Tigers went 10-7 including a perfect 7-0 record at home, and were the runner-up in the Ivy League with a 6-1 record, with that lone loss coming in overtime. Princeton made its third appearance in the Ivy League Tournament, falling in double overtime loss to Dartmouth, 11-10. The Tigers faced Duke in the first round of the NCAA Tournament, suffering another double overtime defeat. The game was named a Game of the Year finalist in the InsideLacrosse.com year-end awards.

The Ivy League trophy returned to Old Nassau in 2014, as Princeton shared the title with Penn and was the No. 1 seed in the Ivy League Tournament, as it beat Penn in a head-to-head battle. The Tigers defeated Penn State in the first round of the NCAA Tournament and lost by just two goals to final four team Virginia in the second round in Charlottesville.

Princeton won its second consecutive Ivy League title, this time with a perfect 7-0 record, and went on to win the Ivy League Tournament Championship. The Tigers reached the NCAA quarterfinals after defeating Fairfield and Stony Brook in the first and second rounds. Though the eight-game win streak ended in Durham in the NCAA quarters, it was Princeton's longest streak since the 2009 season.

Prior to joining the Tigers, Cook spent the four seasons at her alma mater North Carolina. She coached all aspects of defense and draw work, responsible for team compliance, fundraising and budget, in addition to recruiting, video and practice and game day prep. Cook helped recruit and coach the 2009 national goalie of the year and national defender of the year, in addition to having a player named a 2010 Tewaaraton finalist. In her final season, 2012, Cook's defense ranked third nationally in goals allowed per game.

Prior to re-joining the Tar Heels, Cook was an assistant coach at Drexel during the 2007-08 academic year, charged with coaching the defense.
