Alex S. Hill
Alex joins SSI from Haverford College. He studies diffuse interstellar gas and magnetic fields using radio and optical observations and numerical simulations. For his PhD thesis at UW-Madison, he used the Wisconsin H-Alpha Mapper to show that widespread, low-density ionized gas is a natural consequence of feedback from star formation. In postdocs at CSIRO Astronomy & Space Science near Sydney and Haverford College near Philadelphia, he has investigated the interaction between the Galactic disk and halo. At SSI, he will focus on the role of interstellar dust. He will also have an appointment at the Dominion Radio Astrophysical Observatory in Penticton, BC Canada, working on polarized radio emission from the Galaxy with the Canadian Hydrogen Intensity Mapping Experiment (CHIME).
