General Relativity Research Group (GRRG)

600 Einstein equation blue2

The General Relativity Research Group (GRRG) involves in theoretical research focused on Exact solutions to Einstein’s and Einstein-Maxwell’s field equations involving applications in astrophysical objects. Prof. S. Thirukkanesh, Professor in Mathematics in the Department of Mathematics, is the leader of GRRG, and Prof. F. C. Ragel, Professor of Physics working in the group from Department of Physics. The GRRG collaborates with some overseas theoretical researchers in the field from South Africa and India. Since the GRRG established in 2012 at EUSL, the following high-impact research publications have emanated in reputed international journals indexed by Web of Sciences:

The group is interested in enrolling potential students for PhD/MPhil programmes, who should posses BSc.Hons Degrees with Class (preferably Upper Second or above) in Mathematics or Physics (with a good mathematical background). At present a NRC Studentship for MPhil (2018, 2019) is available for a candidate with B.Sc.Hons. in Mathematics.
