This week’s tweeter is Qingqing Mao, a graduate student at Vanderbilt University.

Qingqing has a wide range of research interests spanning from the structure of our Milky Way to the very large-scale structure of our universe. He has used both SEGUE and BOSS data for his research. Currently his main project is looking at how to identify cosmic voids – which are large underdense regions with very few galaxies – in BOSS data and use them to study cosmology.

Qingqing also participates in SDSS EPO, especially including social network activities and multilingual efforts. He leads our efforts to keep the SDSS Chinese facebook page and SDSS Chinese Weibo updated.

Qingqing has also developed an astronomy iPhone ap, which allows users to explore data of the Cosmic Microwave Background: CMB Maps.

He regularly tweets as @maoqingqing and his personal website can be found at http://mqq.io/.
