News and Events
May 2013 — Seeing double: Another paper from a former RTG undergraduate has been accepted. This one is by Jonathan Rubin, Jonathan Rubin, and Bard Ermentrout, is titled "Analysis of synchronization in a slowly changing environment: how slow coupling becomes weak coupling", and will appear soon in Physical Review Letters.

Our welcome orientation was held today and overall it was a success. The session was attended by about 30 people, including the faculty and postdocs, some of our senior graduate students, all of our incoming graduate students, and some undergraduate students eager to learn about the group . We were especially happy to welcome among us two new postdocs Julia Arciero (coming from University of Arizona) and Stefanos Folias (from Boston University) and four new graduate students: Callie Johnson, Sherry Linn, Pamela Reitsma, and Tracy Stepien.
After breakfast we moved to Room 704 where Jon Rubin began the orientation with an overview of this year's activities and organizational matters. (The notes can be found here.) Then the faculty members of the program, David Swigon, Ivan Yotov, Gilles Clermont, Yoram Vodovotz, Jon Rubin, Brent Doiron, and Bard Ermentrout presented overviews of their research activities, slides of which you can find under the links. We finished with a tasty lunch organized by our helpful staff of Judith Kampert and Melissa Weidman, to whom we hereby thank. For pictures from the event see Photos page.

The first RTG activity will be a welcome/orientation session to be held Saturday, August 23, starting at 9 AM, in Thackeray Hall rooms 704-5. The agenda for this session will be to provide an overview of the group's research activities, of what's in store for the year ahead, and of relevant resources on campus, as well as for all of us to meet in person and get to know each other a little better. All PI's and training faculty are welcome to give an overview of the relevant research projects with which they are involved. There will not be a precise timetable for the session but we'll aim to have lunch, which will be provided, around noon.
