Welcome!
Hi, I am Jan, and I work on AI & security. The performance, impact, and importance of AI is rapidly increasing, and my mission is to make it more secure, trustworthy, respectful of privacy, and robust. Presently, I am a researcher at the Czech Technical University in Prague (CTU) and the founder & AI specialist at BohemAI, an AI development & consultancy company. I hold a doctorate in Computer Science from the University of Amsterdam and a master’s degree with honours in Artificial Intelligence from the CTU.
