CP3-Origins currently has the pleasure of hosting Sam Wong, a postdoc at Columbia University.

Sam is currently interested in various topics of Cosmology. In particular he is interested in consistency relations which relates higher point correlation functions to lower point correlation functions. Theoretically, it is interesting to see how of such relation come from the underlying symmetry (diffeomorphism) of the gravitational theory while there are lots of subtleties. Phenomenologically, such relation encodes important information about the early universe dynamics such as degrees of freedom involved during inflation or break down of slow roll.
He has also worked on landscapes in string theory, sphalerons and holography in cosmology.
