Welcome to my homepage. I am a Post Doctoral Fellow in High Resolution Science at CSIRO
Astronomy and Space Science,
based in Marsfield, Sydney.
My basic research interests, in broad terms, cover Masers, Asymptotic Giand Branch (AGB) and post-AGB stars (Mira Variables in particular), radio and sub-millimetre wavelength astronomy and Very Long Baseline Interferometry (VLBI). More specifically, I am interested in understanding the properties of circumstellar envelopes in AGB stars and study their dynamics, kinematics and magnetic fields. The mechanisms of mass-loss and pulsation are of particular importance in order to reveal the properties of circumstellar envelopes.
A very fascinating stage in the evolutionary path of AGB stars, is their transition to Planetary Nebulae (PN). In the short period that this transition covers (~1000 years), stars expell water in highly collimated jets at very high velocities. This very rare objects (13 found so far in our galaxy) are known as "Water Fountains". Their motion and properties can be studied through high-resolution VLBI observations of the water masers. My research is currently focused on the above areas.
In this website you can find details about me, my current and past research projects, a list of publications, photos and videos, my contact details and some useful links.
