Courses & Teaching
Dr. Alex S. Hill is an astronomer who joined the faculty at UBC Okanagan in 2019. After completing his PhD in Astronomy at the University of Wisconsin-Madison in 2011, he held research positions at the Commonwealth Scientific and Industrial Research Organisation’s Australia Telescope National Facility in Sydney, Haverford College near Philadelphia, and at the Dominion Radio Astrophysical Observatory near Penticton, BC. His research focuses on gas and magnetic fields between the stars in the Milky Way galaxy.

Research Interests & Projects
Most of my research is carried out (either virtually or in person) at the Dominion Radio Astrophysical Observatory near Penticton.
- Galactic science as part of the CHIME cosmology team
- Understanding magnetic fields in the Milky Way
- Characterization of the CHIME telescope’s beams
- Radio observations of magnetic fields and ionized gas
- The Global Magnetoionic Medium Survey (GMIMS)
- A survey using the Dish Verification Array (DVA) telescope at DRAO. I am actively looking for 1-2 students to work on characterizing and commissioning the DVA telescope to carry out this survey.
- Upgrading the DRAO Synthesis Telescope with broadband capability to achieve arcminute characterization of the magnetized, ionized gas in the Galactic plane
- The multi-phase interstellar medium
- Numerical simulations of supernova-driven turbulence
- Ionization of interstellar gas
- The role of magnetic fields in the multi-phase interstellar medium
