Kris Sigurdson
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.〔(Kris Sigurdson ). UBC Physics & Astronomy People Directory. Retrieved on 2012-03-03.〕 He was previously a NASA Hubble Fellow〔(Listing of all Hubble Fellows ). Space Telescope Science Institute. Retrieved on 2012-03-03.〕 and Member of the Institute for Advanced Study.〔(Previous People ). IAS School of Natural Sciences. Retrieved on 2012-03-03.〕 He received a Ph. D. in physics from the California Institute of Technology.〔(2005 Commencement ). California Institute of Technology. Retrieved on 2012-03-03.〕
Sigurdson is known for his work on the effects of dark matter interactions on cosmological perturbations,〔(What Mass Are the Smallest Protohalos? ). Physical Review Letters.

''The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos''. Page 166.〕 His other work includes contributions in the physics of the early universe, cosmological perturbation theory, and cosmic 21-cm fluctuations.〔(Publications ).

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.〔(Hylogenesis: A Unified Origin for Baryonic Visible Matter and Antibaryonic Dark Matter ). Cornell University Library. Retrieved on 2012-03-03.〕 The theory predicts that in the long term protons or neutrons can be destroyed by interactions with dark matter.〔(Baryon destruction by asymmetric dark matter ). Physical Review D. Retrieved on 2012-03-03.〕
