April 24th 2014: First Young Researcher Meeting

In order to discuss suitable ways for a regular Young Researcher Forum the IPP invited PhDs and Postdocs to a first meeting.

A common brainstorming revealed that expectations of such a forum vary strongly. However, a new format was developed which combines different aspects of interdisciplinary exchange, networking, and discussing research. We will keep you updated about further steps and we will soon publish more information.

New research ideas often grow in interdisciplinary environments where every scientific discipline is able to express certain problems from their point of view. Therefore the IPP is currently working on a new format regarding the exchange of ideas between young researchers.
The first meeting of the group will take place on April 24th at 4pm in the "Old ReWi" building, second floor room 111.

At this get-together we would like to discuss concepts for a future “Young Researchers Forum”. One of the goals of the research unit IPP is - among others - to bring together researchers and fresh ideas from different research disciplines. This forum shall be a regular opportunity for interdisciplinary exchange.

We would be happy to see many of you next Thursday.
