Bayesian postdoc in Confœderatio Helvetica

Posted in Mountains, Statistics, Travel, University life with tags , , , , , , , , , on April 13, 2018 by xi'an

Antonietta Mira (Università della Svizzera italiana, Lugano) sent me this call for a postdoctoral position between Villigen, near Zürich, hence this picture) and Lugano:

Postdoctoral Fellow: Data Science/Bayesian Inference on Neutron Spectroscopy Data

Your tasks

The increasing availability of empirical large-scale neutron time-of-flight spectroscopy data and steady improvements in computational capacity have resulted in challenges as well as opportunities. This interdisciplinary SDSC-funded project “Bayesian parameter inference from stochastic models (BISTOM)” aims at developing statistical methods and software for analyzing 4D neutron spectroscopy data of quantum magnets. The project is co-directed by Prof. Dr A. Mira (Data Science Center at USI), Dr C. Albert (Eawag), and Prof. Dr Ch. Rüegg (PSI and Univ. Geneva).

Your profile

  • PhD in physics, statistics, applied mathematics or computer science
  • Solid background in neutron spectroscopy or computational statistics/Bayesian inference
  • Strong computational skills
  • Strong scientific writing and communication skills in English

Your working place will be PSI, Villigen and USI, Lugano.

We offer

Our institution is based on an interdisciplinary, innovative and dynamic collaboration. If you wish to optimally combine work and family life or other personal interests, we are able to support you with our modern employment conditions and the on-site infrastructure. Your employment contract is initially limited to 2 years, but may be extended up to 4 years in combination with other grants/fellowships e.g. Marie-Curie.

For further information please contact Prof. Dr Christian Rüegg, phone +41 56 310 47 78. Please submit your application online (including CV, list of publications and addresses of referees) for the position as a Postdoctoral Fellow (index no. 3004-00).

over the Bernese Alps [jatp]

Great views of the Bernese and Grisonese Alps on both legs of my trip to and from Venezia. Flying over Les Diablerets, Bormio and many other places I visited over the years..

at the foot of Monte Rosa

After last-year failed attempt at climbing a summit in the Monte Rosa group, we came back for hiking on the “other side” of Monte Rosa, at the Italian foot of Dufourspitze with less ambitious plans of hiking around this fantastic range. Alas the weather got set against us and thunderstorms followed one another, making altitude hikes unreasonable because of the fresh snow and frequent fog, and lower altitude walks definitely unpleasant, turning the trails into creeks.

While we had many nice chats with local people in a mixture of French and Italian, and sampled local cheese and beers, this still felt like a bit of a wasted vacations week, especially when remembering how reasonable the weather had been the week before in Scotland. However, all things considered, the previous week had seen a deadly heat wave cross the south of Europe that very week, so I should not be complaining about rain and snow! And running a whole week checking the altimeter instead of the chronometer is a nice experience.

Ueli Steck dies on Nupse [Ueli Steck tödlich verunglückt]

Ueli Steck was a Swiss climber renowned for breaking speed records on the hardest routes of the Alps. Including the legendary Eigerwand. And having been evacuated under death threats from the Everest base camp two years ago. I have been following on Instagram his preparation for another speed attempt at Everest the past weeks and it is a hug shock to learn he fell to his death on Nupse yesterday. Total respect to this immense Extrembergsteiger, who has now joined the sad cenacle of top climbers who did not make it back…

ABC in Les Diablerets

Posted in Statistics with tags , , , , , , , , , , on February 14, 2017 by xi'an

Since I could not download the slides of my ABC course in Les Diablerets in one go, I broke them by chapters as follows. (Warning: there is very little novelty in those slides, except for the final part on consistency.)

Although I did not do it on purpose (!), starting with indirect inference and other methods inspired from econometrics induced some discussion in the first hour of the course with econometricians in the room. Including Elvezio Ronchetti.

I also regretted piling too much material in the alphabet soup, as it was too widespread for a new audience. And as I could not keep the coherence of the earlier parts by going thru so many papers at once. Especially since I was a bit knackered after a day of skiing….

I managed to get to the final convergence chapter on the last day, even though I had to skip some of the earlier material. Which should be reorganised anyway as the parts between model choice with random forests and inference with random forests are not fully connected!

The short course I gave in Les Diablerets, Switzerland, was highly enjoyable, at least for me!, as it gave me the opportunity to present an  overview of the field, just before our workshop in Banff and to stay in a fantastic skiing area for four days! While I found out that my limited skiing skills are gone even more limited, the constant fresh snow falling during my stay and the very small number of people on the slopes made the outdoor highly enjoyable, the more because the temperatures were quite tolerable. The above picture was taken on the only morning it did not snow, with a nice cloud inversion over the valley separating France and Switzerland.
