Olle Häggström (born 4 October 1967) is a professor of mathematical statistics at Chalmers University of Technology.

Häggström earned his doctorate in 1994 at Chalmers University of Technology with Jeffrey Steif as supervisor.

These include: In 2016, Häggström published (via Oxford University Press) Here Be Dragons: Science, Technology and the Future of Humanity, an attempt to draft a road map of potential dangers that could be associated with various emerging technologies: "There is no denying that advances in science and technology have brought us prosperity and improved our lives tremendously... but there is a flip side: some of the advances that may lie ahead of us can actually make us worse off.

On geoengineering, Häggström discusses a proposed form of geoengineering that involves continuously pumping sulphur dioxide into the atmosphere to counteract global warming, and warns this could create a catastrophic risk of a massive temperature spike if a future generation were unable to continue pumping.

[8] On nanotechnology, Häggström discusses concerns about self-replicating nanobots, as well as the potential for emerging manufacturing technologies to undo existing gun control measures and to radically upscale the quantities of existing weaponry, and to create destabilizing new classes of weapons.
