Is Ali Hazelwood a pseudonym?
Yes, Ali Hazelwood is a pen name. Her real name has not been publicly disclosed, a deliberate choice she made to separate her academic career from her writing life.
What is Ali Hazelwood’s real name?
Her real name remains private. Bibliographic sources such as Goodreads and Waterstones list her only as Ali Hazelwood, and no authoritative source has confirmed her birth name.
Why does she use a pen name?
She chose a pseudonym to maintain a boundary between her neuroscience professorship and her romance writing career. As she explained on her official site: “I’m originally from Italy, lived in Japan and Germany, and eventually moved to the US to pursue a Ph.D. in Neuroscience.” That academic identity required separation from the public persona of a romance novelist.
“I’m originally from Italy, lived in Japan and Germany, and eventually moved to the US to pursue a Ph.D. in Neuroscience.”
— Ali Hazelwood, official author site
Bottom line: Ali Hazelwood writes under a pen name to keep her academic past and author career distinct. No confirmed real name exists in public sources.
Is Ali Hazelwood still a professor?
She no longer works as a professor. After earning a PhD in neuroscience and teaching for several years, she left academia to write romance novels full time.
What was her academic background?
Ali Hazelwood earned a PhD in neuroscience, a detail confirmed by her Waterstones author profile. Her research focused on the brain, and that scientific rigor shows up in her characters, nearly all of whom work in STEM fields.
Did she leave academia to write full-time?
Yes. After her debut novel The Love Hypothesis became a bestseller, Hazelwood transitioned out of teaching. Her Goodreads bio now describes her as an author of “contemporary romcom novels about women in STEM and academia,” a shift from her previous academic role.
“I write contemporary romcom novels about women in STEM and academia.”
— Ali Hazelwood, Goodreads bio
What this means: Hazelwood traded the lecture hall for the writing desk. Her neuroscience training still informs her books’ STEM settings and characters.
In what order should I read Ali Hazelwood books?

Thematic reading order
Some readers prefer grouping by genre. The STEMinist novella trio — Under One Roof, Stuck with You, Below Zero — works as a thematic set about women in engineering and science. Bride and Mate form a paranormal cluster published in 2024–2025.
Standalone vs series
Every full-length novel is a standalone story. SpinToRead notes that “Hazelwood’s full-length novels are standalone and can be read in publication order rather than series order.” The Contented Reader agrees: “There is no required reading order because her books are standalone romances.”
Tip for new readers: Start with The Love Hypothesis to experience Hazelwood’s signature STEM-romance formula at its best. It also helps you gauge whether you prefer her campus contemporaries or her paranormal entries like Bride.

Is Bride spicier than her other books?
Yes. Multiple sources, including Editors Reads, describe Bride as Hazelwood’s most explicit book. The paranormal premise allows for heightened tension and more sexually charged scenes compared to her campus contemporaries.
Age suitability: Hazelwood’s adult books are intended for readers 18 and older. Check & Mate is the only YA title in her catalog and contains less explicit content.
What is Ali Hazelwood’s most popular book?
The Love Hypothesis is her bestselling and most recognized title. It launched her career and continues to dominate her catalog in sales and reader engagement.
