Jeffries_Rob

I was appointed to a lectureship at Keele in 1995 and promoted to Reader in 2001. Prior to this I was a post-doctoral research assistant in X-ray astronomy at the University of Birmingham and this is also where I obtained my PhD in 1991.

I am a Science, Technology, Engineering and Mathematics (STEM) Ambassador with a remit to promote the public understanding of science and widening participation in higher education. These include school visits, tours of Keele observatory and adult and continuing education courses. See my website for details.

Jeffries Stars like the Sun or of even lower mass are born in clusters and associations. I search for young Suns, low-mass stars and brown dwarfs in star forming regions and clusters in order to find how common they are in a variety of environments and follow the temporal evolution of their discs, rotation rates, magnetic activity and chemical abundances.

The goals are to understand the way in which birth environment influences the development of low-mass stars (and their planetary systems) and to investigate the astrophysics, such as mixing, convection and magnetic fields, that are incorporated into pre main sequence evolutionary models.
