About

Thuong Hoang Currently (2023), I am a postdoc at BICEP/Keck group at University of Minnesota. I obtained Ph.D in Physics of the Universe from AstroParticle and Cosmology (APC) laboratory, University of Paris, in 2018. After completing PhD, I did postdoctoral research at Cornell University, Kavli IPMU-University of Tokyo.

Research (for public)

Standard Cosmological Model

Generally my research contributes to the standard cosmological model (see Figure) of the Universe. My research interests span both observational cosmology on Cosmic Microwave Background (CMB) Radiation measurement and roles of magnetic fields in star formation.

Most of my work has been working on the systematic effects of CMB polarization measurements, focusing on simulation and instrumentation of superconducting Transition Edge Sensor (TES), half-wave plate system for CMB experiments.

On the other hand, I am also investigating data analysis of magnetic fields in molecular clouds to study the evolution and formation of stars.

I have been contributing to several CMB projects QUBIC, Simons Observatory, CMB-S4, and LiteBIRD satellite.

I have published scientific journals and conference proceeding papers. > Read more about my Research.
