Hi, welcome to my website! I am a PhD Candidate in the Earth Sciences department at the University of Oregon. My research is primarily focused in space physics and planetary science. I seek to understand the magnetospheric dynamics of planets with complex magnetic fields such as those of our Solar System's Ice Giants (Uranus and Neptune) and Earth during geomagnetic reversals. My secondary research is focused on applying deep neural networks to identify minerals on planetary surfaces from orbit using infrared spectroscopy data.

Research Interests

Earth's magnetic field protects the planet from high-energy particles from the Sun. Little is known about what happens to Earth’s magnetic field during a geomagnetic pole reversal, yet pole reversals occur regularly on geological timescales. Previous studies suggested that during pole reversals, Earth's magnetic field becomes more complex, taking on the appearance of magnetic quadrupoles, and the overall magnetic field strength decreases. The presence of strong quadrupole fields are also evident in other planets in our Solar system. I seek to understand the magnetospheric dynamics of planets with complex magnetic fields such as those of our Solar System's Ice Giants (Uranus and Neptune) and Earth during geomagnetic reversals.

Significant scientific interest exists for unveiling the surface composition of Mars. Typically this composition is found using infrared spectroscopy from orbit. Current manual methods for performing infrared spectroscopy are very tedious and time consuming, and automated methods rely on detection of limited factors and are incomplete. My secondary research is focused on applying deep neural networks to identify minerals on planetary surfaces from orbit using infrared spectroscopy data.
