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.
- 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.
- "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."
