I’m interested in astronomical ‘Big Data’: developing and applying methods and algorithms that let us use large data sets to answer research questions. Major astronomical surveys of today are routinely collecting hundreds of terabytes of images, creating databases with billions of objects and several billion measurements. Large surveys astronomers are becoming part data scientists. In my research, I go where the data takes me — I’ve worked on topics ranging from asteroids in the Solar System, Galactic structure, to the scale structure of the universe. My current focus is using survey data to understand the structure and evolution of the Milky Way. I also lead the Data Management team for the Large Synoptic Survey Telescope, a project to build the largest sky survey ever undertaken.
