Dr Sergey Koposov


My research is focused on working with large surveys, big data, building statistical models, analysing Milky Way halo, stellar streams and dwarf galaxies.

I am currently a professor in Carnegie Mellon University, and affiliated lecturer in Cambridge aiming to spend ~ one summer month each year in the IoA.
