He is known for his research on the hypothesis that impact events are the cause for mass extinctions on Earth which culminated in his book La Vie en catastrophes, or “Evolutionary catastrophes” in English.
Courtillot is a prominent french climate change skeptic who has been associated with Claude Allègre (described as a “a reliable sidekick to Allègre” by RealClimate ), and is a member of the Academic Advisory Council of the Global Warming Policy Foundation (GWPF).
Stance on Climate Change
“It is true that carbon dioxide has increased dramatically in recent decades. And if I am not persuaded that the effect on global temperatures is shown, nothing prevents these effects occur in the future (one of the main risks is ocean acidification).” 
“In recent interviews, journalists often start by insisting on the fact that I am 'close to Claude Allègre'. This is certainly true and has been for 40 years. It does not mean we think alike on all matters, we both are free and independent scientists.” 
“Together with Jean-Louis Le Mouël and some Russian colleagues, we have shown that some specific features of the magnetic field were remarkably well correlated with some variations in the sun’s activity - which in itself was not surprising - but the fact that it also correlated with the mean global temperature of the lower atmosphere came to us as a real surprise. This is how I started to get interested in climatology at the decadal to centennial time scale, an area which is not my specialty, though I had already encountered climatologists at the million year time scale with the Indian volcanism.”
“It is clear that oil, gas and coal resources will eventually be depleted someday and to be reasonably cautious about decreasing consumption is a necessity. It does not need to be related to a legal precautionary principle.” 
Courtillot contributed a presentation to a Climate Report by the French Academy of Sciences. According to Courtillot, “There was no other 'labeled climate-skeptic' presentation, but a number of presentations were critical of significant aspects of the majority view as expressed by the IPCC reports.”
His presentation was “on observations of recent climate change and our published work on evidence for solar forcing.” 
Vincent Courtillot and two other members of the Institute of Earth Physics of Paris (IPGP) were accused of a breach of publishing ethics for acting as editors for dozens of papers by IPGP colleagues from 1992 to 2008 in the journal Earth and Planetary Science Letters while they were members of the editorial board. 
Courtillot was a member of the journal's editorial board from 2003 to 2005, and was the head of the IPGP from 2004 to 2011. 
The controversy also invovled the publication of one of his own papers titled “Are there connections between the Earth's magnetic field and climate?” by V. Courtillot, Y. Gallet, J.-L. Le Mouël, F. Fluteau, A. Genevey (2007) EPSL 253, 328.
The issue was covered by the French magazine Le Monde, although the original article no longer appears to be available. The blog Rabett Run offers an excerpt and translation of the original article which discussed Courtillot's potential conflict of interest. Science also offers an article, however it requires a subscription. 
In terms of the scientific merits of their article, RealClimate offers a critique of Courtillot's paper where he had argued that fluctiations in the Earth's magnetic field (due to the Sun) may drive climate change. 
According to RealClimate, the paper contains “a number of errors of a more troubling nature” including a “misleading impression of the comparison of forcing by solar variability relative to greenhouse gas forcing by failing to take into account the Earth’s spherical geometry and albedo.”
A sample of Courtillot's publications is available at IPGP. His work appears mainly int he area of geophysics and geomagnetics.
According to an interview at the GWPF, “He is also the co-author, with Jean-Louis Le Mouël, of some nine scientific publications in the past five years on climate that have passed the standard filter of scientific publications in international peer-reviewed journals.”
