Sanna is social psychologist. Over the last decade, her research has focused on our capacity to change our behaviour—and how this skill shapes our ability to flourish in different environments and roles.

When she found herself unexpectedly single, Sanna noticed the sheer volume of noise and harmful narratives around dating and long-term relationships. From the myths of perfect, effort-free romance to “opposites attract”, what we consume is at odds with the beautiful mess that is a romantic relationship. We don’t enter relationships as fixed beings, but naturally adapt and change over time.

Her observations led her to apply her research to the domain of modern love, in which she now explores:

• What if love isn’t something we find—but something we build?

• What if compatibility isn’t about fitting together, but changing over time?

• What if the goal isn’t to avoid life’s ups and downs, but to learn how to move through them with someone?

Today, Sanna is a regular keynote speaker on behaviour change, wellbeing, and romantic relationships. She dispels myths and offers tangible tools to help people better understand themselves and their relationships. She is currently developing a podcast with Audible Originals, that explores how to live in the gap between our expectations and reality.

Her first book on modern love will be published by HarperCollins and Hachette in 2027.

Sanna received her PhD from the University of Cambridge. Based in London, she spends her spare time pondering life’s complexities—often beginning with her cat.
