Biography

I am an astrophysics PhD candidate at the University of Surrey under the supervision of Denis Erkal and Justin Read. My main research interest lies in stellar streams and whether they are sensitive to time-dependent, deforming dark matter halos. The Milky Way is currently deformed by the infalling Large Magellanic Cloud. Which streams are affected and can trace this?
