I am the Leon Lederman Fellow at the Fermilab Center for Particle Astrophysics.

Before joining Fermilab, I was a graduate student in the Department of Physics and Astronomy at Texas A&M University, working with Dr. Jennifer Marshall and Dr. Darren DePoy in the Munnerlyn Astronomical Instrumentation Lab. I received the Eramus Mundus Scholarship for a Joint European Master in Space Science and Technology (SpaceMaster), during which I stayed in Germany, Sweden, France and Japan for 6 months each. I completed my undergraduate at Fudan University in Shanghai, China, with a major in Physics and a minor in Diplomacy.

I'm an observational astronomer as well as an instrument builder. My scientific interests include near-field cosmology, Galactic archaeology and metal-poor stars. My current main work is to study the Milky Way halo substructures, including the stellar streams and dwarf galaxies. I am working on spectroscopic follow-ups on individual stars to study the kinematics and metallicities of those substructures, using telescopes at McDonald/HET and LCO/Magellan, etc.

My instrumentation work involved designing and building the auxiliary calibration systems, namely aTmCam and DECal, for the Dark Energy Survey (DES), to improve the precision of the photometric calibration to better than 1%. Working on this infrustrature work in DES has also brought me the DES Builder status, which entitles me to be listed as an author on every DES collaboration-related paper, and personal data right, which allows me to keep working on the DES data after I graduate from Texas A&M University. I have also worked on a few other instrumentation projects, such as the Giant Magellan Telescope and the HETDEX project, etc.

(Ting Li is really the most common name in China, so it's really a pain to find my own papers. I therefore decided to go with T. S. Li from 2015. )
