Ali Hazelwood is the New York Times and Sunday Times bestselling author of The Love Hypothesis, Love on the Brain, Love Theoretically, Check & Mate, Bride, and Not in Love, 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. She recently became a professor, which absolutely terrifies her. When Ali is not at work, she can be found running, eating cake pops, or watching sci-fi movies with her two feline overlords (and her slightly-less-feline husband).
