Research Student

Room Number: G. O. Jones Building, Room 502


During my 1st year as a PhD student I taught 1st year undergraduate Classical mechanics and Special Relativity problem classes and marked weekly courseworks, as well as invigilated exams.


Research Interests:

I am a final year PhD student at Queen Mary working with Dr. Timothy Clifton. My interests are in theoretical cosmology and applications of general relativity to cosmology. My research uses exact solutions of the Einstein field equations to analytically construct inhomogeneous cosmological models in order to compare them to FLRW universes. This is to investigate the role of small scale inhomogeneities on large scale structure and late time behaviour. So far I have generalised existing work by considering a cosmological constant and its implications as well as the role of structure formation and interaction energies.

Public Engagement

I am passionate about science communication, whether it is through more formal teaching (outreach) or informally talking to members of the public about my research (public engagement).

Previously I worked part-time as the STFC Astronomer at the Royal Observatory in Greenwich, alongside my doctoral studies. I delivered masterclasses to secondary school students on a variety of topics, such as stellar evolution and observational astronomy, and also briefly spoke about my own research. I also delivered careers workshops, predominantly for Key Stage 3 students where we discussed who/what a physicist is/does. An exciting part of this role was also to deliver Planetarium shows in the Peter Harrison Planetarium.
