I am primarily interested in using a combination of simulations, statistics and observations to answer questions about our Universe. Recently, I have used strong gravitational lensing and Bayesian inference techniques to constrain ultra-light dark matter theories. I have also worked on 21cm cosmology, from a theoretical and experimental perspective. For instance, I have investigated the effect of spin temperature on the relationship between matter and ionized hydrogen during the Epoch of Reionization with MCMC methods.

I study the physics in stellar atmospheres. The physics is intriguing because the conditions, which cannot be recreated in our labs, are changing extremely rapidly between the dense stellar interior and the near vacuum of space. However, we have the great advantage of being able to observe directly the brightness and spectrum of the stellar atmosphere. A recent revolutionary observational development is the technique of optical/infrared interferometry that resolves the surfaces of the nearer stars. My approach concentrates on the bright stars that can be observed in the greatest detail, and to interpret those observations using computer models
Ting’s research focuses on near-field cosmology. In particular, she studies the stars in the Milky Way Galaxy and nearby galaxies to understand how they form and to understand the nature of dark matter. She specializes in analyzing large data sets from modern surveys and also performs traditional astronomical observations with optical and near-infrared telescopes. Ting also builds astronomical instruments and contributes to infrastructure work for large-area sky surveys such as the Dark Energy Survey (DES), Dark Energy Spectroscopic Instrument (DESI), and others. She is the founder and leader of the Southern Stellar Stream Spectroscopic Survey (S5), a survey to map streams of stars in the sky visible from the Southern Hemisphere to determine the mass profile of the Milky Way. She is also one of the convenors of the DES Milky Way Working Group, as well as one of the Dark Matter Working Group co-chairs of the Maunakea Spectroscopic Explorer, a 11.25-meter telescope facility dedicated to the next generation spectroscopic surveys.
I was born and raised in Shanghai, China. I received my bachelor degree in astronomy at the University of Science and Technology of China (USTC). My research interests cover a wide range but focus on galaxies. In my spare time, you can see me playing badminton/swimming/jogging. I enjoy traveling in different countries and visiting museums.

I hail from the sunny region of Southern California, where the abundance of dark sky preserves sparked my fascination with the cosmos. My current research is centered on the first observations of massive stars that have had their hydrogen envelopes removed by their binary companions. These stripped stars hold great significance in nearly every realm of astrophysics, spanning from potential sources of gravitational waves to their role in cosmic reionization.
