She also regularly shares her knowledge of business communication on international podcasts, interviews, and virtual events.

When this bestselling author isn’t obsessing about effective communication, she watches television to unwind. A huge fan of detective programmes, she fancies herself an expert in identifying the culprits. She also enjoys watching thrillers, (meaningful) action flicks, and dramas.
