Geraint is the head of the Gravitational Astrophysics Group at USyd.

 When not asleep at the telescope, his research includes cosmology, general relativity, gravitational lensing, galactic cannibalism and basically anything else that interests him.

 Nick is a postdoctoral research.

  He currently works with Pan-Andromeda Archaeological Survey (PAndAS) data, and continues to be interested in gravitational microlensing of quasars

James Allen is a postdoctoral researcher.

He works on large-scale galaxy surveys, combining information from large numbers of galaxies in order to better understand the processes that drive their formation and evolution. He is particularly interested in the relationship between active galactic nuclei and star formation.  A significant part of this work consists of developing new statistical tools that allow us  to make sense of the vast quantities of data generated by modern surveys

Anthony is a PhD student at Macquarie University working with Geraint   on data from the Pan-Andromeda Archaeological Survey (PAndAS).

His PhD research is concerned with developing a robust, Bayesian algorithm capable of locating the tip of the red giant branch with consistent accuracy of better than 0.05 magnitudes. This is now up and running and in the process of being applied to the various substructures in the M31 halo in an effort to accurately obtain their distances.

Holly is a PhD student.

She is studying the formation of the large scale structure  of the universe. Currently, she is looking at how dark matter structure influences the spins of galaxies and using N-body simulations to do cosmology. She is also interested in theories of gravity and dark energy. Holly is a Sagittarius and out of all the fundamental forces, her favourite is gravity.

  Tom is PhD Student working on the growth of Supermassive black holes and their role in galaxy evolution.

His research involves the use of N-body simulations to quantify the effectiveness of processes like dynamical friction, three body scattering and gravitational recoil at various stages in the history of the universe. At present there is a multitude of formation theories for these massive bodies which appear to lie at the  heart of all galaxies, however little distinction can be made due to a lack of observable evidence.

     Prajwal is a PhD student currently looking at the behaviour of the stellar halo of our own the Milky Way Galaxy.

 He is trying to constrain  the formation history of the galaxy by the study of the kinematics of the stellar halo. Whether the stellar halo is rotating or counter-rotating is the one of the interesting ideas he is currently checking

Foivos is PhD student who trying to understand a bit more,  what's this thing called dark matter. His research focuses on  the analysis of kinematics of Dwarf spheroidal galaxies and globular clusters,  through dynamical theories and Bayesian statistics methods.

 He is also passionately and incurably in love with advanced mathematics  and his natural environment: liquid space, and feels gratitude for he found plenty of both in Sydney.

    Magda is a PhD student, working on the evolution of the Magellanic Clouds.

     In particular, she is trying to re-build the genetic inheritance of the Clouds, in order to describe how the past of these galaxies has influenced their interaction with the Galaxy.

Francesca is a PhD student investigating how gravitational lensing can be used to estimate the amount of dark matter in the universe.

    Her main interest is theoretical cosmology, ranging from the differential geometry of various spacetimes to properties of dark energy.  She spent her Honours year getting  her hands dirty with numerical simulations, using Markov Chain Monte Carlo methods to estimate the fractional matter and dark energy content of the universe and investigating non-Λ CDM dark energy models.

       Her present research focuses on gravitational microlensing for cosmological purposes.

 Brendan is a PhD student, working on  galactic evolution using Bayesian voodoo on the Pan-Andromeda Archaeological Survey (PAndAS) data  of M31 and M33.

His interests cover all things General Relativity, having just spent his  honours year studying the effects of Alcubierre Warp Drive on light and matter.

Hareth is working on a project aims at develop methods to determine the amount of dark matter substructure in haloes of galaxies by looking at the lensing signature it produces.

 He is trying to construct and develop both analytical models and numerical simulations in order to achieve the purpose of his study. His research interests focus on the dark matter issues and lensing phenomenon of different classes (i.e. strong, weak and microlensing).
