The image above was created using all the titles of my publications (as of 04.Mar.2015) using wordle.net.
I study the interaction of exoplanets with their host star's wind, and how this interaction can affect planetary habitability. For that, I develop 3D simulations of winds of low-mass stars stars, which permeate entire exoplanetary systems.

I am an assistant professor in Astrophysics at Trinity College Dublin. Prior to that, I held independent research fellowships from the Royal Astronomical Society (at University of St Andrews, UK) and from the Swiss National Science Foundation (at Geneva Observatory).

Research Interests

Stellar Winds

Solar-like stars (main sequence and pre-main sequence) & low-mass stars: magnetised coronal winds, rotating outflows, structure of the coronal magnetic field, angular momentum loss, magnetic interaction between planets and the host star, accretion disks.

Exoplanetary Magnetic Fields

Formation of bow shocks due to magnetic interaction between planets and the host star. Radio emission through electron-cyclotron maser instability.

Magnetohydrodynamics Waves

Cool supergiant stars: models of winds driven by Alfven waves, wind heating by dissipation of Alfven waves, charged dust-wave interaction.

Magnetohydrodynamics Numerical Simulations

Three-dimensional simulations, time-dependent effects, adaptive mesh refinement.
