Welcome! I am a Rutherford Discovery Fellow at the University of Otago, New Zealand, and a part of Otago space physics. Our group studies 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, 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

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