“Nature is the realization of the simplest conceivable mathematical ideas.”
— Albert Einstein

I hold a Ph.D. in Physics with a specialization in experimental research on fundamental quantum gases. This challenging and dynamic field provides me with the comprehensive knowledge and experimental skills required to delve into the mysteries of nature. My research centers on the fundamental principles of superfluidity and superconductivity across various temperatures.

Quantum physics has been a lifelong passion, one to which I have dedicated years of study, mastering its core principles and exploring the intricate physical world it describes. Through rigorous research, I have developed expertise in conducting advanced quantum experiments, including building and operating sophisticated devices—circuitry, lasers, and optical spectrometers—alongside performing hyperfine spectroscopy to trap, cool, manipulate, and probe atomic quantum states.

In addition to my physics background, I am an experienced software engineer with a strong grounding in engineering principles. This dual expertise empowers me to design and implement complex software systems. My computer science interests, particularly in computer vision and machine learning, have led me to develop a range of research tools for the scientific community. These skills are instrumental for running simulations and building essential software that advances my research and contributes to the broader field.

May 28, 2019	Presentation at 50th Annual Meeting of the APS Division of Atomic, Molecular and Optical Physics APS Meeting Presentation: The Structure of Polarized Vortices in the Unitary Fermi Gas Abstract: Fermionic superfluids do not generally support polarization, and the nature of the ground state of a slightly polarized unitary Fermi gas remains an open question. However, vortices naturally support polarization since the pairing gap vanishes in the core of superfluid vortices. The structure of a polarized vortex is not well understood, and may have some interesting properties. To study the microscopic structure of a vortex, we use a density functional theory called the asymmetric superfluid local density approximation (ASLDA) to simulate how vortexes interact, evolve and how energy transfers between paired and unpaired particles. In this talk, I will discuss the structure and properties of polarized vortices using the ASLDA, and how these related to polarized phases through the Thomas-Fermi (TF) approximation.
