Born in 1990. Personally, I am the father of twins – Ignacy and Antoni, husband to Marta and owner of Kiara. Professionally, I am a scientist who is especially interested in personality research. Most of my works are devoted to studying the dark side of personality, with special place for studying narcissistic personality. However I am also interested in positive psychology as well as in the studies on eating disorders. Apart from that, I specialize in the psychological assessment.
