Dr. Pierre Chang is a fictional character portrayed by François Chau on the ABC television series Lost. Introduced in the second season as a theoretical astrophysicist working for the Dharma Initiative and appears primarily in orientation films. In the fifth season episode "Follow the Leader", Chang learns that crew member aboard the Kahana, Miles Straume (Ken Leung) is his son. In 1977, during the events leading up to the Incident, Chang is present at the Swan Station during drilling operations. When the drill strikes an electromagnetic pocket, he is caught in the resulting disaster and loses his arm. After these events, he is not seen again in the main timeline, and it is suggested that he dies during the purge.

According to Chau, the character was given a French first name and an Asian surname, a combination connected to the actor himself. Chang usually wore professional-looking attire in his orientation videos, often including a white coat, which featured either a Dharma Initiative Flame or Swan logo. Chang's appearance in a Dharma Initiative video shown at Comic-Con led to discussion among viewers about unseen footage and the possibility of his return, particularly in connection with the orientation recordings and Daniel Faraday's (Jeremy Davies) storyline.^[1]

Pierre Chang appears in a series of Dharma Initiative orientation films recorded during the 1970s under aliases such as Dr. Marvin Candle, Mark Wickmund, and Edgar Halliwax, including a 1980 Swan station film shown to Jack Shephard (Matthew Fox) and John Locke (Terry O'Quinn) in which he outlines the Dharma Initiative, founded by Gerald and Karen DeGroot and funded by Alvar Hanso, explains the Swan as an electromagnetic research station, describes an earlier incident, and instructs that a code must be entered into a computer every 108 minutes to prevent another event, while warning against using the system for other purposes, with the film cutting off abruptly, after which Jack dismisses it as a social experiment while Locke accepts it, and Desmond Hume (Henry Ian Cusick) unsuccessfully attempts to power the computer before fleeing.^[2]

Chang appears in a random-access procedures video on the Flame station computer, unlocked through a chess program, where he explains system overrides and a self-destruct protocol to be used in the event of a Hostiles incursion, wearing a Dharma lab coat marked with the Flame logo and not identifying himself.^[3] Chang appears in a orientation video for the Barracks viewed by young Ben Linus (Sterling Beaumon) and Annie (Madeline Carroll), and in later recordings warns personnel about restricted areas such as the sonic fence while providing safety guidance about the Island's hazards, with these materials later discovered by the survivors of Oceanic Flight 815 crash and serving as key information.^[4]

In 1977, Chang lives on the Island with his wife Lara (Leslie Ishii) and infant son, serving as a senior Dharma scientist involved in station operations and recruitment during a time of growing instability within the Initiative.^[5] During this period, Chang repeatedly crosses paths with Miles Straume (Ken Leung), who has traveled back in time from 2004. Miles is working in Dharma security but keeps their connection hidden at first. Over time, Chang grows suspicious that Miles is his son. Chang was warned by Daniel Faraday (Jeremy Davies) that drilling at the Swan station could trigger a major electromagnetic disaster, a claim he initially dismissed but reconsidered after following Hugo "Hurley" Reyes (Jorge Garcia), Miles, and Jin-Soo Kwon (Daniel Dae Kim) toward the beach, where Hurley failed to answer basic questions about "1977" and admitted he was from the future, and Miles confirmed that Chang was his father, convincing Chang that time travel was occurring and that Faraday's warning was true.^[6]

Chang then returns to the Dharma barracks and orders an evacuation of the Island due to the danger of the Swan project. However, Dharma leadership under Stuart Radzinsky (Eric Lange) refuses to stop the drilling.^[7] At the Swan construction site, Chang attempts to stop the drilling as energy levels spike sharply. The drill eventually breaks into an electromagnetic pocket, causing a violent release of energy known as the Incident. In the collapse, his left arm is trapped and badly injured while he escapes.^[8]

After the Incident, Chang survives and later appears in the Swan orientation film explaining the button system and referencing what happened during the Incident. He is shown wearing a prosthetic hand following his injury.^[8] In the 2007 flash-sideways timeline, Chang works as a museum scientist alongside Charlotte Lewis (Rebecca Mader). His son Miles becomes a police detective. Chang also appears at a museum fundraising event organized by Hurley and later introduces a benefit concert featuring Daniel and Charlie Pace (Dominic Monaghan) with his band Drive Shaft.^[9]

In the epilogue, Chang continues appearing in Dharma Initiative orientation materials, explaining station functions, alternate identities, and experimental procedures, while also answering operational questions about multiple Dharma stations and their purposes. At the Dharma Logistics Warehouse in Guam, Ben (Michael Emerson) shows Dharma personnel Hector (Ted Rooney) and Glen (Ray Porter) the Hydra orientation video featuring Chang, in which he explains Room 23, experiments on polar bears, the Hurley-birds, and his use of aliases in other instructional videos.^[10]

Cambodian actor François Chau was originally cast for a single orientation film appearance as Marvin Candle. The role was expected to be short-term but continued after the orientation videos gained attention from viewers and production staff.^[11] The first film was recorded on a reused set from Alias, a series also created by J. J. Abrams. Early recordings took place in Burbank before later production moved to Hawaii as the character became part of the main Dharma storyline.^[12]

Chau described the audition process as "straightforward", noting he performed a long monologue in a single take. According to Chau, his character who works within Dharma science while making decisions that affect others, including sending his family off the Island for safety reasons.^[11] The role expanded further once the series introduced time travel storylines and placed the characters in 1977, allowing Chang to appear in live action scenes rather than only recordings.^[13] The Los Angeles Times noted that Chang is shown as a parent who sends his wife and child off the Island for safety, a decision often interpreted as protective during unstable conditions on the Island.^[14] A Comic Con screening of a Dharma video raised discussion among viewers about unseen material and possible future appearances of Chang, especially in connection with Dharma recordings and Daniel Faraday's storyline.^[1]

In 2024, filmmaker Taylor Morden and the producers behind Getting Lost an independent documentary about the making of and cultural impact of the television series released a promotional video featuring Chang. In the video, Chau reprises the role and invites viewers to learn more about the project through its IndieGoGo crowdfunding campaign.^[15]

Pierre Chang became one of the most memorable recurring figures in Lost due to the Dharma orientation films.^[12] Ryan Smith of Comic Book Resources described Chang as a central mystery within the series and noted that his storyline connects directly to Miles Straume’s personal history.^[16] Nathan Sharp of Screen Rant described Chang as an important Dharma figure whose actions influence major events on the Island, especially those involving Dharma infrastructure and his family.^[17]

Jack Greer of ComicBook.com wrote that a storyline is developing between Chang and Miles and said it would likely be expanded by the producers. He suggested Chang is not as strict as he initially seems, and that he and Miles may grow closer, even predicting that the two could end up sharing a connected fate.^[18] Noel Murray of The A.V. Club describes Chang in his Dharma Initiative instructional films, including those for the Arrow station. During one recording, he is interrupted by a Dharma worker who reports a problem at the Orchid station, where extreme heat is causing drilling equipment to melt. One of Chang's names is Marvin Candle, his favorite alias.^[19]
