プロフィール概要

Research experience includes advanced technology development in the fields of plasma physics, magnetic reconnection, and magnetic shielding of radiation. I have also done extensive work in the field of solar atmospheric physics. I earned my PhD in 2013. My skills lie in the computational modeling of complex three-dimensional magnetic field configurations, magnetic field evolution, and the optimization of charged particle tracking simulations through such fields. I also specialize in two- and three-dimensional visualizations of the resulting fields and particle tracks. These established coding techniques are highly adaptable and can be applied to a variety of geometries for a variety of problems.

Torsional magnetic reconnection derived from resistive magnetohydrodynamics equations @article{10.1063/5.0272452, author = {Chesny, D. L. and Hatfield, K. W. and Cassibry, J. and Moffett, M. B.}, title = {Torsional magnetic reconnection derived from resistive magnetohydrodynamics equations}, journal = {Physics of Plasmas}, volume = {32}, number = {7}, pages = {072110}, year = {2025}, month = {07}, abstract = {The onset of magnetic reconnection results from the diffusion of the magnetic field through a resistive plasma due to the imbalance between plasma pressure and magnetic pressure (plasma β parameter). In following a generalized procedure to solve for a two-dimensional (2D) Sweet–Parker diffusion region, we have extended this analysis to the three-dimensional (3D) case of torsional magnetic reconnection (TMR). One key advancement of the 3D case over the 2D case includes imposing a geometrically localized plasma resistivity profile to explore how magnetic field diffusion arises at t=0 without deriving an analytical electric field or reconnection rate. Analytical solutions to the resistive magnetohydrodynamics (MHD) equations are given for both the torsional fan reconnection and torsional spine reconnection cases. Numerical solutions identify localized regions of magnetic field dissipation, enhanced pressure gradients, and helical motions, which together suggest the transition from a low-to-high plasma β and magnetic reconnection. Comparisons of these diffusion region locations to relative helicity dissipation are demonstrated, thus highlighting the importance of tracking helicity during TMR. These analytical procedures can be used to study the onset and evolution of any 3D reconnection mode without having to undertake complex time-dependent resistive MHD modeling architectures.}, issn = {1070-664X}, doi = {10.1063/5.0272452}, url = {https://doi.org/10.1063/5.0272452}, eprint = {https://pubs.aip.org/aip/pop/article-pdf/doi/10.1063/5.0272452/20596666/072110\_1\_5.0272452.pdf}, } .
