Jim Halverson is an assistant professor of physics at Northeastern University in Boston, Massachusetts.
His research is at the interface of string theory, particle physics and cosmology, and mathematics. He is particularly interested in the string landscape and its implications for particle physics and cosmology beyond their standard models. These implications often follow from the structure of extra-dimensional geometries, of which there are many possibilities. Halverson’s research therefore requires importing techniques from mathematics and computer science.
