According to a short bio I read on a wiki, "Not much is known about Cohen's early life. She was born and raised in Toronto, Canada. From 2000 to 2004, she attented the University of Toronto. In 2008, she became an alum of Warner Bros Television Writers' Workshop.
Cohen eventually became a TV writer and producer. Her first credit as a writer was an episode of Degrassi: The Next Generation in 2009. In the following years, she worked on Space's Bitten, Global's Bomb Girls and CBC's Being Erica.
From 2012 to 2014, Cohen wrote five episodes of TNT's Dallas, and was also credited as a story editor for the entire third and final season. Since then, her other television credits include The Royals, Riverdale, Caught or Quantico."
