Kris Sigurdson is a Canadian physicist and cosmologist. He is an associate professor in the University of British Columbia's department of physics and astronomy in Vancouver, British Columbia.[1] He was previously a NASA Hubble Fellow[2] and Member of the Institute for Advanced Study.[3] He received a Ph.D. in physics from the California Institute of Technology.[4]

Sigurdson is known for his work on the effects of dark matter interactions on cosmological perturbations,[5][6] new models of dark matter particle physics,[7][8] and the potential for observing signatures of the multiverse with cosmology.[9][10] His other work includes contributions in the physics of the early universe, cosmological perturbation theory, and cosmic 21-cm fluctuations.[11]

In 2010, he co-authored a paper proposing the theory of hylogenesis, a theory of the origin of matter that links the formation of dark matter to baryogenesis.[12] The theory predicts that in the long term protons or neutrons can be destroyed by interactions with dark matter.[13]
