As a person born in Russia I find the current war started by Russia against the people of Ukraine abhorrent. I fully support Ukraine in the defence of their country.

Russia, stop the war and leave Ukraine!

To students

I am accepting new PhD students. I am also happy to chat to any PhD or undergraduate students interested in galactic archaelogy, statistics or machine learning. Every year I usually propose several MPhys and Senior Honour projects.

To postdocs

If you are looking to apply for one of the fellowships (Rutherford, Royal Society or others) and are interested in doing it in Edinburgh and work in the general area of Galactic archaeology, please check this page for a list of opportunities, and feel free to contact me to help with the application process and sponsor your application. Keep in mind that many of the applications have an internal (within Edinburgh) selection process, so please contact me in advance. On top of fellowships listed earlier, other options are: Chancellor fellowship, Elizabeth Gardner fellowship.

Research interests:

  • Dwarf galaxies
  • Stellar streams (See S5 project)
  • Milky Way structure
  • Gaia
  • Stellar dynamics
  • Stellar chemistry
  • Binary stars
  • Hyper-velocity stars
  • Large surveys
  • Databases
  • Data mining
  • Statistics

I created and support the large SQL database of all astronomical surveys called WSDB (whole sky database). If you are interested in using it, and/or have big data/data mining ideas, please contact me.
