CIRM in dire need of help

The International Mathematics Conference Centre, CIRM, located in Luminy, Marseille, France, has been deeply disrupted by the COVID-19 pandemic. Up to 60 % of the events planned there have been cancelled so far and all remaining conferences have gone virtual or at best hybrid, open to a remote audience, including in an interactive way. This has required important and unexpected investments. Furthermore, this crisis happened at the worst possible moment as CIRM had just finished doubling its infrastructure capacities. This is why I strongly support the call from the French Mathematical Society (SMF) to make a donation to CIRM before the end of the year, especially from researchers who benefited from its hospitality and unique environment.

Wagram, morne plaine!

Avenue de Wagram is one of the avenues leaving from Arc de Triomphe in Paris, named after a (bloody) Napoléonic battle (1809). This is also where I locked my bike today before joining my son for a quick lunch and where I found my back wheel completely dismantled when I came back!  Not only the wheel had been removed from the frame, but the axle had been taken away, damaging the ball bearing… After much cursing, I looked around for the different pieces and remounted the wheel on the bike. The return home to the local repair shop was slower than usual as the wheel was acting as a constant brake. I am somewhat bemused at this happening in the middle of the day, on a rather busy street and at the motivation for it. Disgruntled third year student furious with the mid-term exam? Unhappy author after a Biometrika rejection?

Not a great week for biking since I also crashed last weekend on my way back from the farmers’ market when my pannier full of vegetables got caught in between the spokes. Nothing broken, apart from a few scratches and my cell phone screen… [Note: the title is stolen from Hugo’s Waterloo! Morne plaine!, a terrible and endless poem about the ultimate battle of Napoléon in 1815. With a tenth of the deaths at Wagram… Unsurprisingly, no Avenue de Waterloo leaves from Arc de Triomphe! ]

my talk in Newcastle

I will be talking (or rather zooming) at the statistics seminar at the University of Newcastle this afternoon on the paper Component-wise approximate Bayesian computation via Gibbs-like steps that just got accepted by Biometrika (yay!). Sadly not been there for real, as I would have definitely enjoyed reuniting with friends and visiting again this multi-layered city after discovering it for the RSS meeting of 2013, which I attended along with Jim Hobert and where I re-discussed the re-Read DIC paper. Before traveling south to Warwick to start my new appointment there. (I started with a picture of Seoul taken from the slopes of Gwanaksan about a year ago as a reminder of how much had happened or failed to happen over the past year…Writing 2019 as the year was unintentional but reflected as well on the distortion of time induced by the lockdowns!)


away from CIRM

Due to the new lockdown measures enforced in France and in particular in Marseilles, the CIRM workshop on QMC and randomness has turned virtual, and I will thus give my talk on Coordinate sampler : A non-reversible Gibbs-like sampler from Paris. Rather than from the Luminy campus after an early morning run to the top of Mont Puget as we used to do on the previous workshop there. With versions of PDMP running on QMC (which makes sense when considering the deterministic component of the sampler).
