How stars move in dense stellar systems is a much more complex problem that seems, and it is deeply intertwined to a number of complex astrophysical and relativistic phenomena
Gravitational Waves sources for ground-based detectors
Ripples in space and time from stellar-mass compact objects and black holes.
Gravitational wave sources for space-borne observatories
Observing gravitational waves from supermassive black holes will allow to test General Relativity in the strong regime
Supermassive Black Holes and Tidal Disruptions of Stars
A star venturing too close to a supermassive black hole may end up being torn apart.
The unknown nature of the dark matter of the Universe and the understanding of gravity are among the more tantalizing problems in modern physics.
With photons we can see, with gravitational waves, we can hear.
The formation and evolution of protoplanetary systems, the breeding grounds of planet formation, is a fascinating complex dynamical problem that involves many orders of magnitudes.
High Performance Computing
The evolution of N-body systems, like galactic nuclei or globular clusters, is a source of different astrophysical phenomena which can be simulated using computational algorithms.
my topics of research
My background is in theoretical physics. I did my PhD research on stellar and gas dynamics. For about 12 years I worked at the Albert Einstein Institute in Golm, Potsdam, close to Berlin, where I was the group leader of Astrophysics. At the AEI I worked on gravitational waves physics. I broadened my experience, working on planetary formation theory with numerical simulations. I have recently expanded my interests to sources of X-ray emission, such as the tidal disruption of a star, accretion power mechanisms and the electromagnetic emission associated to these phenomena. I am interested in GPU computing, in particular in developing new algorithms in stellar dynamics written in CUDA. Find more about me here.
This is the strongest point of my expertise.

astrophysics is becoming one of my main interests
astrophysics - I have developed from scratch a novel hybrid algorithm to study their formation, and a new GPU Nbody code
