I'm a postdoc at ICFO, the Institute of Photonic Sciences in Barcelona. My research is on strong-field and ultrafast physics, and I study tunnel ionization and high-harmonic generation.
Check out my papers - they're nice!

My PhD thesis is available here. It deals with the tunnel effect, and how you can build trajectory based models even when the particle is under the barrier. This requires the time to be complex and, as I show, the same is true of the position ─ with some nontrivial interpretation issues ;-). I gave an overview talk at a recent workshop and the video is here.
My profile picture shows the polarization ellipses of high-order harmonics emitted by p-shell atoms in 'bicircular' fields, from figure 4 of the rotating-frame paper.
I've also got a couple of Mathematica projects over on GitHub,
RB-SFA, a package to calculate high-harmonic generation (HHG) emissions in the strong-field approximation (SFA), by direct time integration of the Lewenstein model.
QuODD: Quantum Orbits Dynamic Dashboard, a package to visualize the effect of complex time contours on the complex trajectory for the quantum orbits formalism of strong-field physics.
