He is the son of Nobel Prize-winning physicist Werner Heisenberg, who was a co-founder of the quantum mechanics, and who, in particular, introduced the uncertainty principle.

During his early career at Stanford and MIT, Heisenberg participated in numerous experimental studies of nuclear reactions.

[1] After his move to the University of New Hampshire (UNH), he began to study methods for theoretical prediction of such reactions.

[2] Heisenberg has spoken several times to provide a historical perspective on the activities of his father during and after World War II.

He has been invited to comment on Michael Frayn's well-known play Copenhagen[3] and has published his perspectives on his father's activities.
