My research consists in doing theoretical, numerical and observational investigations
on massive stars, from their evolution away from the Main Sequence (through
to the supergiant, Luminous Blue Variable and Wolf-Rayet phases), to
the collapse of their core, identified as a Type II/Ib/c supernovae explosion.

Since the end of my Ph.D., I have moved on and away from the steady-state analyses of Wolf-Rayet
stars to focus on the structure and dynamics of radiatively-driven winds of
hot stars, from a general standpoint.
On the one side, I have been working with Stan Owocki on the small scale structure
of hot star winds, which touches closely the mechanism of line-driving which
is at the origin of the resulting overall properties, i.e. the terminal velocity
and mass loss rate.
Click here for
a detailed account on that work, which started out in the fall of the year 2000.
I have also worked independently on the large scale properties of line-driven
winds, first walking in the footsteps of
Stan Owocki and Steve Cranmer,
and later on extending their work, from the physical/numerical side, as well
as exploring new observational constraints (e.g. with interferometry,
in collaboration with Olivier Chesneau, Observatoire de Nice).

I have a lengthy pdf
seminar-like presentation (prepared for the GRETA and Nice visit in May 2004)
that covers all these aspects
from close and far, from observational and theoretical viewpoints, with lots of
cartoon physics and illustrations on the small and large scale properties
of line-driven winds.
Since May 2003, I have also been working in collaboration with
John Hillier
on the quantitative spectroscopic analysis of Type II supernovae.
Our work is based on CMFGEN, a non-LTE atmosphere code that had thus
far been used for investigations on massive stars, as well as
central stars of planetary nebulae.
Things are progressing and we now have a wide range of results
pertinent to the photospheric evolution of Type II supernovae, such
as SN1987a and SN1999em.
In March 2005, I came to Tucson to work with
Adam Burrows on radiation
magneto-hydrodynamics studies of core-collapse supernovae.
