About my research: I'm a M.Sc. Astrophysics student, working within the Compact Binary Group in the Institute. I'm currently doing my thesis on "Testing the third body explanation for eclipse timing variations in PCEBs" with the aim of explaining the origin of the variations observed in this system. The specific goal of my thesis is to obtain the orbital parameters of possible planetary orbits around the binary star system RR Cae, via statistical methods (specifically MCMC), and determining the stability of the orbit of this possible planet.

About my research: My research is focused on circumstellar disks, and using observations to constrain the methods of planet formation within them, either around young stars or evolved binaries, and I use some of the newest instruments and techniques available to achieve this.

About my research: My thesis project focus on the gravitational lens effect at different scales in the Universe. At small scale, I study microlensing light curves to detect exoplanets. At large scale, I search for microlensing effect in lensed quasar systems to study the inner structure of the quasar and also the lensing galaxy. At a larger scale I perform dynamical analysis of lensing galaxy groups.
