Welcome! I am a Rutherford Discovery Fellow at the University of Otago, New Zealand. Along with students and collaborators, I study a variety of topics in astrophysical fluid dynamics and plasma physics. We focus on understanding how basic dynamical processes – e.g., instabilities and  turbulence – affect astrophysical systems and processes like the solar wind, stars, galaxy clusters, accretion disks, the interstellar medium, and magnetogenesis. Our research involves a mix of analytic "pen and paper" theory, numerical simulations, and code development.

Please visit my research page or publications for more information, or take a look at my CV. I currently have openings for graduate students — if you are interested in joining the group for a project, shoot me an email at                                                         jonathan.squire [at] otago [dot] ac [dot] nz

Or, just take a look at some fun climbing photos

A standing shear-Alfvén wave, simulated using the hybrid-kinetic PIC code Pegasus. As the wave oscillates, it is "interrupted" and excites the firehose instability.

About me

I grew up in Dunedin, New Zealand, doing an undergraduate degree in physics with music on the side at the Univerity of Otago. I then went to Princeton University for graduate school, funded by a Fulbright Science and Technology fellowship, and studied at the Princeton Plasma Physics Laboratory, graduating in 2015. After 2.5 years at Caltech astrophysics as a postdoctoral fellow, I decided I wanted to come back to New Zealand, making the return to Otago in 2018.
