Numerical Study of Coronal Mass Ejections, Shocks, and Turbulence: from Chromosphere to 1 AU.
(2014)
My dissertation focuses on one of the major source of destructive space weather: coronal mass ejections (CMEs). By helping develop and utilizing a new data-driven global MHD model: The Alfven Wave Solar Model (AWSoM) in ...
Evolution of Flux Transfer Events at the Magnetopause: MMS Observations and Global Hybrid-Vlasov Simulations
(2019)
Magnetic reconnection is the underlying physical process responsible for the release of energy stored in magnetic fields that powers plasma heating and acceleration. Flux transfer events (FTEs) are transient signatures of ...
Characterizing Heliospheric and Interstellar Interactions Using Pickup Ion Measurements
(2022)
The Heliosphere, orbiting the galactic center of the Milky Way, is a plasma bubble carved out of the Local Interstellar Medium (LISM) by the Sun's dynamic and magnetic influence. Its relative motion creates a steady inflow ...
The Significance of Proton Beams in the Multiscale Solar Wind
(2019)
The solar wind is a multiscale, near-collisionless plasma. Three significant timescales are decades, days, and seconds. These timescales are associated with the solar cycle, Coulomb collisions, and instabilities, ...
Understanding the Impacts of Mesosphere and Lower Thermosphere on Thermospheric Dynamics and Composition
(2021)
The Earth’s Ionosphere and Thermosphere (IT) is a highly dynamic system persistently driven by variable forcings both from above (Solar EUV and the magnetosphere) and the lower atmosphere. The forcing from below accounts ...
Separable Inverse Problems, Blind Deconvolution, and Stray Light Correction for Extreme Ultraviolet Solar Images.
(2013)
The determination of the inputs to a system given noisy output data is known as an inverse problem. When the system is a linear transformation involving unknown side parameters, the problem is called separable. A quintessential ...
A Data-Driven Understanding of Plasma Transport in Saturn's Magnetic Environment
(2020)
In 2004 the Cassini-Huygens mission arrived at Saturn. As the first ever Saturn
orbiter, Cassini collected data reaching from the largest moon, Titan, at 20 Saturn
radii (Rs), to the atmosphere during its death plunge in ...
