I hear that some senior PIs are seriously giving talks about replacing PhD students with armies of robotic arms and agents. Personally I’m not sure PIs aren’t easier to replace… in what world are we living.

and it happened : I just came to realize I didn't fly for work in 2025 (I did fly a bit for personal reasons). It wasn't an objective per se, but just being (a bit) picky, and looking for train alternatives when possible did the trick. and I did go to IT, NL, CH, UK, GE, CZ.

A merry Christmas from the COMEDIA team at LKB !
A graphic visualization representing a Christmas tree formed entirely of keywords on a black background. The terms are colored in red, pine green, gold, and silver. In the center, the names 'Sylvain' and 'Hilton' as well as the year '2025' appear in very large characters. The branches of the tree are made up of technical scientific terms such as 'Complex Media', 'Transmission Matrix', 'Raman', 'Quantum Imaging', 'Speckle', and 'Neural Networks'. The image symbolizes the scientific production and research axes of the laboratory for the past year.

Back home after a great 3-day trip to the NL, for the NNV-AMO meeting, and visiting COPS in Twente and Allard Mosk's group at U. Utrecht. No cheese this time, but I couldn't come back with a collection of great PhD thesis :-). (why do we do A4 format in France? this is soooo much better!)

A strong quality for a good researcher is the ability to sometimes ignore small details, and sometimes delves into them with the greatest care, and more importantly to being able to switch wisely between the two modes.
