Research

As a member of the Solar Physics and Space Plasma Research Centre at the University of Sheffield, I currently research in solar magnetohydrodynamic waves under the supervision of Prof. Róbert von Fáy-Siebenbürgen. I have previously completed research in meterology and photovoltaics.

Solar Magnetohydrodynamic waves

Waves are a ubiquitous feature of the magnetically dominated solar atmosphere. This is continually demonstrated with ever-improving spatial and temporal resolution observations of ground- and space-based solar telescopes.

Magnetohydrodynmics (MHD) is the mathematical study of the motion of electrically conducting fluids and provides an appropriate mathematical framework to study many solar structures because the Sun is made up of plasma, which, due to atom dissociation, is electrically conducting.

My interest in solar MHD waves stems from:

  1. their potential for large scale energy transport from the cool solar surface to the extremely hot atmosphere, and
  2. their use in magneto-seismology: estimating parameters such as the magnetic field strength which are difficult or impossible to measure accurately using traditional methods.

Meteorology

Aussie heat low

The effect of the Coriolis force is to give a moving object a force perpendicular to its velocity. This rotational effect introduces some interesting phenomena such as Rossby waves which are large-scale atmospheric waves that oscillate around the globe which can break, causing violent cyclones. Rossby wave breaking has been linked to extreme weather events in Australia.

During a visit to Monash University, I worked with the School of Earth and Atmospheric Science to assess and compare the simulation of a large area of low pressure in central Australia caused by intense heating. We showed how crucial the lower boundary conditions are to the accurate simulation of this heat low; in particular, how parameters such as the soil moisture content and surface albedo are to the precipitation cycle that is interwoven into the formation of the heat low. This research allows scientists to improve global climate models for inproved climate predictions in the future. See publications section.

Photovoltaics

I am interested in renewable energy alternatives and have previously completed research into optimising the geometry of photovoltaic panels, using analytical and numerical methods, to determine whether alternative curved geometries would increase the incident radiation gathered by a planar geometry.

Outreach


Conferences, workshops, and seminars

I often get lost at conferences and seminars when presenters jump straight into their research without context or motivation, so I always include a introduction to the context of my research within the broader field. As a visual learner, I make use of videos and images to most effectively portray an idea.

Highlights:

  • Nervously presenting some results from my Masters research project at the National Astronomy Meeting in 2016.
  • Illustrating at the European Solar Physics Meeting in 2017 how my theoretical work on asymmetric MHD waves can be used to approximate the strength of the magnetic field in structures in the solar atmosphere - something that is traditionally very difficult to do.

Below is a list of the conferences, workshops, and significant seminars I have attended and/or contributed to.
