Hi there, welcome to my space! I am a PhD student studying Computational Astrophysics at the University of Wyoming. I have a broad interest in the intersection between astronomy and computational science. As a current Wyoming resident, I consider myself a digital cowboy riding on the supercomputers.

Growing up near the gorgeous mountains Qinling 秦岭 , I am an outdoor adventurist. My current location, Laramie, is surrounded by beautiful mountains, and I enjoy hiking, snowshoeing, and skiing among them. I occasionally post some pictures under the photos section.

My research interests include two general directions: Computational & data-driven astrophysics and High-Performance Computing. I am interested in studying compact objects, such as black holes and neutron stars through simulations. I also explore the physics of quasars and galaxy evolution using data mining and machine learning techniques. I am particularly interested in applying HPC to improve and innovate research directions.

Triaxial neutron stars can be sources of continuous gravitational radiation detectable by ground-based interferometers. The amplitude of the emitted gravitational wave can be greatly affected by the state of the hydrodynamical fluid flow inside the neutron star. In this work, we examine the most triaxial models along two sequences of constant rest mass, confirming their dynamical stability. We also study the response of a triaxial figure of quasiequilibrium under a variety of perturbations that lead to different fluid flows. Starting from the general relativistic compressible analog of the Newtonian Jacobi ellipsoid, we perform simulations of Dedekind-type flows. We find that in some cases the triaxial neutron star resembles a Riemann-S-type ellipsoid with minor rotation and gravitational wave emission as it evolves towards axisymmetry. The present results highlight the importance of understanding the fluid flow in the interior of a neutron star in terms of its gravitational wave content.
