**Ali Hazelwood *is the New York Times bestselling author of The Love Hypothesis * as well as a writer of peer-reviewed articles about brain science, in which no one makes out and the ever after is not always happy. Originally from Italy, she lived in Germany and Japan before moving to the US to pursue a PhD in neuroscience. When Ali is not at work, she can be found running, eating cake pops, or watching sci-fi movies with her three feline overlords (and her slightly-less-feline husband).
