Stefan G. Hofmann (born December 15, 1964) is a German-born clinical psychologist. He is the Alexander von Humboldt Professor and recipient of the LOEWE^[1] Spitzenprofessur for Translational Clinical Psychology at the Philipps University of Marburg in Germany, examining cognitive behavioral therapy,^[2] especially for anxiety disorders.^[3][4][5]

Since 2012, he has been editor in chief of the journal Cognitive Therapy and Research.^[6]

Hofmann was born on December 15, 1964, in Bietigheim-Bissingen.^{[citation needed]}He majored in Psychology at the Philipps University of Marburg, where he eventually earned his Ph.D. in 1993.

Hofmann has been studying the nature of emotional disorders and the processes through which psychological treatments alleviate symptoms by translating discoveries from emotion research and neuroscience into clinical applications.

An important mechanism of exposure therapy for anxiety disorders is extinction learning. Hofmann has shown that d-cycloserine, a partial agonist of the glutamate receptor can augment extinction learning and speed up exposure therapy of anxiety disorders.^[7]

Some of his other major contributions are on Mindfulness and research on Emotion in therapy. In particular, he advanced the concept of Interpersonal emotion regulation.

In collaboration with Steven C. Hayes and David Sloan Wilson, he has been developing Process-based Therapy (PBT), an idiographic treatment approach based on cognitive behavioral therapy that combines insights from evolution theory and complex network theory to target processes that underlie effective psychological treatments.

Hofmann has published more than 400 peer-reviewed scientific articles and 20 books and is listed by Clarivate Analytics and the Institute for Scientific Information as a ISI Highly Cited Researcher.^[8]
