Introduction
I primarily examine political communication on social media, trying to understand the reasons why politicians turn to these platforms for public communication. My interests also include Czech local politics and the broader landscape of electoral behavior. Recently, I have started to look at the impact of artificial intelligence on society, with a particular focus on large language models and chatbots, such as ChatGPT. In 2023, I received my PhD from the University of Hradec Kralove.

Dear Editor,
We have read recent publications on ChatGPT in the Journal of Public Health with keen interest.
