PhD Student // Cosmology

  • Hi there,
    I am a graduate student at the Johns Hopkins University. My research focuses on theoretical and computational cosmology. I am currently working with Profs. Marc Kamionkowski and Tobias Marriage.
    My CV can be viewed here.

inflation / cosmic microwave background / 21cm

I am interested in the physics of and beyond today's standard cosmological model.

Currently I am a member of the Cosmology Large Angular Scale Surveyor (CLASS).
Its primary goal is to detect and characterize the primordial B-mode polarization of the Cosmic Microwave Background,
which is a unique signature left by the primordial gravitational waves as posited in the theory of Inflation.

Previously I have been working on theoretical aspects of large-angle anomalies
-- phenomena revealed by measurements of the microwave background that are statistically unlikely to occur in the standard model.

  • My life (or the lack of it) outside Physics

    I was born and raised in Shanghai, China, and then came to the United States for undergraduate study in 2012. Philosophy has been my passion ever since I read Sophie's World in middle school, and so I attended the University of Pittsburgh. How I decided to be a physicist... can be a story for another day.

    In essence, it is the same passion for the knowledge of nature that led me to the study of physics and philosophy -- we observe nature as a complexity, and through human ingenuity we disentangle the natural phenomena, and thus disenchant the world. In studying these two disciplines, I sense the power of mind: the ability to reach to the very beginning of the Universe, and to search for the answers to the oldest and deepest questions in the history of humanity.

    This is the journey which I would like to take on.

    P.S. If you are curious, I invite you to my-occasionally-updated blog, where I have posted some of my essays.
