The Ally McBeal/Numb3rs vet will play Assistant Director Stavros Sifter, 40, a career FBI insider and supervisor of Special Agent Avery Ryan (Patricia Arquette) for the Cyber Crime Division in Washington, D.C.
Sifter quickly rose up the ranks and positioned himself in a job where he is the clearinghouse between FBI Cyber and all other branches of government. He is a shrewd and savvy networker — a charmer with a hint of malice.
The CSI: Cyber cast also includes Community‘s Charley Koontz as Agent Daniel Grummitz.
MacNicol’s recent credits include guest stints on The Mindy Project and Marvel’s Agents of S.H.I.E.L.D.
CBS is eyeing a midseason launch for the CSI spin-off.
