On the first day of grad school for her PhD, a fellow student tells Bianca Jones Marlin that she doesn't really belong there.

Bianca Jones Marlin is a neuroscientist and doctoral candidate at New York University, School of Medicine. She received dual bachelor degrees in biology and adolescent education from St. John's University. Her time as a high school biology teacher led her to the laboratory, where she now studies the neurochemicals that govern communication and dictate social memories. Bianca investigates how the brain changes in the presence of the "love hormone," oxytocin. Her research aims to understand the vital bond between mother and child, and uses oxytocin as a treatment in strengthening fragile and broken parental relationships. Bianca, a native New Yorker, lives in Manhattan with her scientist husband, Joe, and their cat Santiago Ramon y Cajal, who is named after the famed neuroanatomist.
