What is the relationship between the human brain and behaviour, perception, and cognition? That is the question that occupies Alexander Sack (born in 1972), who has set up two research laboratories at Maastricht University and coordinates his own line of research. As a psychologist and neuroscientist, Sack collaborates with research groups specialising in rehabilitation and neurology but also with forensic investigators. He is also closely involved as an academic advisor in the Studienstiftung des Deutschen Volkes, whose membership consists exclusively of outstanding students with a wide-ranging interest in science and society.
