Dr. Clark Thomas Edison is one of the many squinterns that Dr. Brennan has at the Jeffersonian.


"You know, my parents also travelled quite frequently. I believe I may have some abandonment issues which causes me to be withdrawn... Hence my previous workplace behavior!"
The Body in the Bag

Clark Edison is a doctor who was hired by the Jeffersonian following Zack Addy's departure to Iraq (The Widow's Son in the Windshield). However, his position with the team was short lived when Zack returned later in the episode to retake his position in the lab.

Clark returns in The Verdict in the Story, where he is the scientific counsel for the defense in the murder trial of Dr. Brennan's father, Max Keenan. Clark goes over the evidence against Max meticulously and discovers that the murder weapon is not the one Zack declared it to be, thus causing doubt that Max had indeed murdered FBI Deputy Director Kirby. The defence's advantage was short-lived, however, as the actual murder weapon was shortly discovered in Brennan's home.

After Zack's departure at the end of Season 3, Clark appears in several episodes of Season 4. However, Clark finds it hard to work in the lab, claiming that there was too much interpersonal drama, though he later returns.

Clark returns to the Jeffersonian in The Couple in the Cave after being passed over for a promotion at his job in Chicago. Later in that same season, in The Body in the Bag, viewers learned that Clark held a summer job at the National Security Agency, though he refuses to discuss any details of it.

During Season 6, he lightens up considerably, in part because of his girlfriend's urging him, shares more of his personal life and takes an interest in those of his coworkers

In Season 8 we learn that he took the position of the absent Dr. Brennan, much to the dismay of Angela. He did implement some new methods which were not well appreciated, such as logging all evidence in binders so everyone working forensic cases has access to the same information, but a returning Dr. Brennan, who worked in the lab in secret, remarked that they were really efficient. It becomes obvious that Clark is not very happy with the prospect of Dr. Brennan's return, but he keeps working his best towards exonerating Dr. Brennan for the murder of Ethan Sawyer, despite the possibility that he would lose his position at the Jeffersonian. Nonetheless, he was happy that Dr. Brennan would return to the Jeffersonian following Christopher Pelant's arrest for the murder of Carole Morrissey. At that time, Cam announced that the Jeffersonian was actually in need of two anthropologists, one for the crimes and one to do some serious archaeological work. Clark happily accepts the latter position since Dr. Brennan announces that she loves crime, while he exclaims that he loves archaeology. From this point onwards Clark is mainly involved in cases that either intersect with his archaeological interests or because the "regular" interns are explicitly unavailable.

In The Stiff in the Cliff, Clark becomes a suspect in a murder that took place when he was an undergraduate. Though Clark is exonerated of the murder, its discovered that he unknowingly helped falsify evidence of cannibalism. Though the media is stated to be crucifying Clark and he wants to resign from the Jeffersonian, Brennan comes to his defense, telling Clark that she never believed him to be guilty of the murder and writing an article in the Forensic Anthropology Times defending him. Brennan points out that the entire scientific world bought into Marcus Eldridge's deceit, not just Clark and "mistakes make for better scientists" and every scientist alive has made some sort of mistake. Additionally, Clark was only an undergrad at the time and friends and teammates stand up for each other. Clark is so moved that he hugs Brennan who sends Clark back to work where he belongs.

In The Grief and the Girl, while investigating a murder, Clark realizes that the land the murder occurred on hides a Viking settlement. At the end of the episode, Clark states that he has gotten the funding to begin excavations on the property and permission from the owners to do so. Genetic testing done by Clark shows that one of the owners and the murder victim were also descended from Vikings.
