Cliff Arculin is the alias of Cliff Siljak, who was born April 16, 1958 in Los Angeles, CA. He was formerly a top CIA neural scientist assigned to CIA Psy-Ops, but was shunned by the wider CIA community due to rumors that his experiments fell closer to torture than actual science. The disaffection led to him joining Fulcrum.

He was one of the ten undercover Fulcrum agents based at Meadow Branch who were working on building the Fulcrum Intersect, after Fulcrum's plan to steal the government's First Intersect was foiled by Bryce Larkin. Cliff posed as a husband to fellow Fulcrum scientist, Sylvia Arculin, during their time in at Meadow Branch. When he was pointed out to Chuck, he responds, "He's a big fella, isn't he, what line of work is he in? Lumberjack?"

When Casey ran his bank records it was discovered "...he bought enough of this stuff to stretch from here to Gardena. Infiniband data line. The same stuff we use to tap into the Agency's intranet," making him instantly suspect. The Fulcrum Intersect test station was situated in his house, and it was his supposed wife who invited Chuck over in the form of a proposition, so that they could test it on him.

After a successful upload of the Fulcrum Intersect on Chuck, team Bartowski managed to kill, incapacitate, or incarcerate the entire team after Casey ran the test on the unprotected operatives during their own escape from the facility.
