a day in Chicago

Another busy day as I visited the University of Chicago Booth School of Business. This was my first time visit to this impressive building (and my first visit to Chicago for 25 years…) I actually had to leave Ames at 4:30 (am!) to catch a plane in Des Moines at 6:50 and be at the Chicago Booth before my first appointment at 10… Everything worked out fine, despite the potential for disruption due to the storm Sandy (just spotted a few big waves along the waterfront on my way to the University), and I had a definitely productive sequence of discussions. The talk on ABC was again well-attended and, because this was an econometric seminar (as in Princeton), definitely lively with a flow of questions all along. (There were also a few people from Biology, for whom the focus on our consistency result was presumably less interesting than for econometricians.) As in Ames, I did not manage to reach the part on empirical likelihood. Fodder for another seminar! The day ended by a meal in a superb restaurant with my favourite wine, Saint-Joseph, after which I was ready for a few hours of sleep..! And then a few hours to spend in the Art Institute of Chicago before flying back to Paris. Direct, courtesy of Sandy.

ABC in Le Monde?

In the plane to Chicago, while being stuck on the tarmac at Roissy airport for an hour, I went through my newspapers, only to have the pleasant surprise find in the science leaflet of Le Monde that my co-author Arnaud Estoup, senior researcher at INRA in Montpellier (CBGP), was mentioned in a full page article for his work on the multi-colored Asian lady beetle (Harmonia axyridis, HA), establishing “that the recent burst of worldwide invasions of HA followed a bridgehead scenario, in which an invasive population in eastern North America acted as the source of the colonists that invaded the European, South American and African continents, with some admixture with a biocontrol strain in Europe“. Obviously, Le Monde does not goes as far as mentioning ABC, which was used in our paper to compare scenarios, i.e. to make ABC model choice! (I may also add that the invasion of those Asian bettles in our neighbourhood is a real nuisance and, each Fall, I keep checking for any sign of black beetles inside the house before disaster strikes…)

Despite an inauspicious start (RER B train finishing its trip in Paris and forcing me to board in a hurry a taxi to the airport, abyssal mess at Roissy airport [now, that’s a surprise!], departure delayed by 90 minutes), I got some work done during the nine hour flight, including reading and reviewing a PhD thesis, and I even managed to get my connection from Chicago to Des Moines despite a tight 45 minutes transfer time! At a personal level, this reminded me of the very first time I flew to the US, in August 1987, as it also was through O’Hare and I also had to rush to get my connection to Lafayette, Indiana. Even more anecdotally, this AF0664 flight from Paris to Chicago happened to be the very last one, as the route is discontinued by Air France. The second flight to Des Moines was on a small propeller plane and, despite sitting next to an obnoxious drunk woman who wanted me to know everything about her [dull, so very dull] life, quite pleasant: I finished reading in the Midwest sun the highly entertaining thriller by Cédric Villani, Le Théorème vivant. (Obviously soon to be reviewed on The ‘Og!)

Midwestern trip

Next week, I will visit both Iowa State University, in Ames—a funny item for French speaking readers is that I will first land in Des Moines before reaching (les) Ames!, a logical step if any, even though only the first name relates to the early French exploration of the area: Ames has apparently no [ethymological] connection with souls…—, and the University of Chicago Booth Business School, giving a seminar on ABC model choice and empirical likelihood in both places. (I have never been to Iowa before and the last time I visited Chicago—rather than just commuting through O’Hare—was in May 1988, when I drove a friend to the airport…!) Here are the time and places for the seminars (note that the seminar at Booth is on Tuesday rather than on the customary Thursday to accommodate my tight schedule!):

As a coincidence—not so much as he is currently assistant professor in Ames—, the previous seminar speaker in Ames is my friend Vivek Roy, talking on Monte Carlo Methods for Improper Target Distributions! Here is (again!) the current version of the slides:
