Welcome! I am an Associate Professor at the University of Otago, New Zealand, and a part of the  Otago space physics group. We study a variety of topics in astrophysical plasma physics and fluid dynamics. We focus on understanding how basic dynamical processes – e.g., instabilities and  turbulence – affect astrophysical systems like the solar corona and wind, stars, galaxy clusters, accretion disks, planet formation, the interstellar medium, and cosmic rays. Our research involves a mix of analytic “pen and paper” theory, numerical simulations, and code development.

Or, just take a look at some fun climbing photos

Imbalanced turbulence in the solar wind, simulated using the hybrid-kinetic PIC code Pegasus. The turbulence creates a”helicity barrier”, which causes it to drive small-scale parallel fluctuations that heat the ions.

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 as a Sherman Fairchild postdoctoral fellow at the Caltech astronomy department, I decided to come back to New Zealand, making the return to Otago in 2018.

PhD Projects

If you are interested in a PhD project, please send me an email. We have several different projects available, mostly focused on the heating of the solar corona and solar wind turbulence. Otago has a generous PhD scholarship program, which is open to both domestic and international students.
