Thomas C. Krohn is a Danish author, speaker and writing coach based in Stenløse. With a PhD and a background in neurobiology, research, teaching and medical technology, he draws on science and the human mind to create crime fiction and thrillers. His stories explore questions beginning with “What if?” and weave biological and psychological themes—including viruses, dangerous bacteria, infectious disease, biological weapons and psychopathy—into realistic plots with complex characters. Krohn began writing in 2012 with a children’s book and has since focused on scientific crime and thriller fiction. His titles are published through his own imprint, RosenHill, and include works featuring virologist Jacob Detlev.

Alongside his books, Krohn offers engaging talks on subjects such as psychopaths, biological weapons and his journey as a writer, combining popular science, examples and humor. His writing-coaching service helps aspiring writers brainstorm, organize ideas and receive constructive feedback. The website also features a blog about his books and writing process, travel descriptions and practical tips, as well as a newsletter with updates and a discount on print books ordered directly from him.
