Dates and topics of the famous CATS meeting. All that are interested meet in the AICES seminar room at 13:00 (sometimes at 11:00) to have a nice cup of coffee or tea. Moreover, there will be talks and discussions; the topics are given in the table below. Please don't hesitate to insert more topics if you want, or write an email to Sarah.

There is a calendar for the MSO at our internal webpage. Once you add the wiki-catsinternal to your iCal, you will be able to see it. Please refer to our IT team for instructions on iCal.
