Gabriel Sitter is a Physics major with a focus in Quantum Physics.  Gabriel's studies led him to join the junior team of the Ghostbusters.
Gabriel Sitter majored in Quantum Physics for his Bachelor of the Arts. He became interested in ghosts only so far as their connection to the harder sciences and wanted to be able to explain them to people by way of quantum physics. He got a part time job with the Ghostbusters to study the connections and help pay for school. Since accepting the position, he grew to appreciate the differences between the natural and supernatural sciences. He even built up a friendly rivalry with Samuel Hazer over which is more important to the world at large.  Gabriel was fascinated with the P.K.E. readings given off by the Cerberus Manifestation. Alan Crendall wanted to draw it away from Bridget before they attacked it. Gabriel realized it was gone.
"The technical genius of the group, he's also not scared of getting his hands dirty when the ghosts try and get up close and personal. Following in Dr. Spengler's footsteps, he's keen to learn more about being a Ghostbuster, and make his own mark unearthing more information on the spectral realm and developing his own new technologies."
