|Specifics: This is for Ghostbusters 101, ATC Comic|
Erin Gilbert is a former professor from Columbia University. She, along with Abby Yates, co-wrote Ghosts from Our Past: Both Literally and Figuratively: The Study of the Paranormal. She is one of the four Ghostbusters in the 2016 movie.
Erin runs the risk of potentially being haughty, as she is shown to be highly concerned with her perception by intellectuals. She is insecure from years of not being accepted by the academic community, and tends to come off as goofy when sharing their company. In fact, Erin is headstrong, believes in the scientific method, and does not easily give up.
She was a professor at Columbia University. One day, Ed Mulgrave Jr. came to her after reading "Ghosts from Our Past Both Literally & Figuratively: The Study of the Paranormal", which she wrote along with Abby. She was unaware of the books publication and was not wanting her representation mucked up by Ghost Chasing non-sense. Ultimately, she found out that Abby was operating her paranormal research at Kenneth P. Higgins Institute.
Abby was not willing to take down the book, but agreed to only if she'd come along with her and Jillian to investigate the haunting at the Aldridge Mansion Museum. While there, she encountered a spirit that slimed her. After the interaction, a video of it was posted online. She was fired from Columbia University shortly afterwards.
Erin found herself once again distracted with Kevin. This time he was dancing near the front door in a broccoli costume with no music on. At first, Erin thought he was doing a take on the traditional Bhangra Dance Style but then he started doing the Mashed Potato. Erin was disappointed when Abby had him practice whatever he was doing in the other room. Abby tried to get her focused on preparing the Ghostbusters for saving the world again. Unlike Abby, Erin was skeptical something bad was on the horizon again since their field was still a new one. Erin lost a coin toss to Abby and had to go over the accounting. She stayed behind at the Firehouse while the others went out on another slew of calls. She reassured herself she loved going over the books and it was the cornerstone of a good business. She discovered an order for 10 cases of spray cheese and on a hunch, asked Kevin if he ordered it. Kevin replied 'possibly'. She reminded him he (and Holtzmann) couldn't just order anything he wanted on the business account then asked him to answer the phone. Kevin wasn't feeling it on account of bad vibes and declined. He called her "Stephanie" instead of "Erin". Mike Hat brought her the phone while she corrected him. Erin informed the caller that the Ghostbusters had a full schedule and couldn't possibly come before 6 pm. The caller said some obscenity that offended Erin and she asked if he kissed his mother with that mouth. Erin wished they could hire more help and imagined Kevin as someone else.
After two Statues of Liberty and another team of Ghostbusters appeared on the news, the team gathered outside the Firehouse. Erin was shocked to see layout of the interior was different and their stuff was gone. She wondered if they were robbed. Kevin Tanaka greeted them from the office. Erin demanded to know where Kevin was. Kevin stated he was Kevin. Erin lost her composure and declared Kevin was a chiseled, godlike, specimen of a man and he wasn't. Kevin remarked he did all right. Patty advised Erin to take a breath. Egon Spengler and Kevin Beckman got their attention from atop the stairwell. The two teams gathered on the second floor to figure out what was going on. Erin was surprised to learn the other team had interns. Janine Melnitz added they also had a branch in Chicago and a a liaison agent with the FBI. Erin asked if they were still hiring. Egon concluded their two dimensions were in a state of overlap. He and Ray Stantz talked about their exploration of the alternate dimensions and shared their theory about seeding the subconscious of the Multiverse with the idea of Ghostbusters. Abby was angry to learn they risked the lives of innocent citizens when they crossed the streams. Erin reminded her they set off a nuclear explosion in Times Square once. Abby told her to be quiet because that was a totally different situation.
- For her lecture at the start of the movie, Erin's Grand Unified Theory was based on the challenge of unifying quantum mechanics and Einstein's gravity. 
- There are even the series of equations involving conformal compensator superfields. They were written by MIT consultant Lindley Winslow and later transcribed on set. They illustrated the failure of a once-promising physics theory called SU(5). 
- Erin was an associate professor and specialized in the study of a subatomic particle called a neutrino, nicknamed the "ghosts of the standard model." 
- In Ghostbusters International #3, on page 6, in panel 5, Erin makes a non-canon cameo as one of the applicants outside.
- On page 17 of Ghostbusters International #7, the whiteboard in panel 6 is a non-canon reference to Erin's equations in the Columbia lecture hall near the start of the movie.
- On page 4 of Ghostbusters International #8, once again on the whiteboard, is the equations written by Erin in the Columbia lecture hall at the start of the movie.
- On page 20 of Ghostbusters 101 #1, right of Kemp's Spectral Field Guide is the photograph of Abby and Erin at their high school fair, seen in the Extended Edition and deleted scenes of the 2016 movie.
- On page 4 of Ghostbusters 101 #2, Erin is wearing her white shirt and jeans outfit from Chapter 16 of the 2016 movie.
- On page 7 of Ghostbusters 101 #3, Erin is in her civies from Chapter 12 from the 2016 movie.
- "That stuff went everywhere, by the way. In every crack. Very hard to wash off."
- ↑ Boston Globe " Meet the MIT physicists who vetted the science in ‘Ghostbusters’" 7/27/16 Line reads: "Winslow herself spent a week writing out a lengthy and elaborate Grand Unifying Theory known as SU(5). (You can spot it in a scene where Wiig's character, Erin Gilbert, while trying to earn tenure at Columbia, prepares to speak on the challenge of unifying quantum mechanics and gravity.)."
- ↑ PC Magazine "Reimagining Ghostbusters, and Proton Packs, for 2016" 7/11/16 Line reads: "The inspiration went beyond just facilities, though. In one scene in the movie, Wiig's Gilbert stands in front of a lecture hall, speaking on challenges of reconciling quantum mechanics with Einstein's gravity. On the whiteboards, behind her, a series of equations tells the same story: a self-contained narrative, written by Winslow and later transcribed on set, illustrating the failure of a once-promising physics theory called SU(5). (Yes, "Pa/RA(NO x RM)alS + UDIes/Lab" might be an easter egg, but "conformal compensator superfields" are a real thing.."
- ↑ Boston Globe " Meet the MIT physicists who vetted the science in ‘Ghostbusters’" 7/27/16 Line reads: "Like Wiig's character, Winslow is an assistant professor. She studies a subatomic particle called a neutrino. So little is known about neutrinos they're called the "ghosts of the standard model," Winslow said."
