Current research on IDS

Hello,

I would like to familarize with the current state of art (and research) on IDS. Unfortunately when I tried to contact with some widely-known scientific groups (columbia university, ibm zurich, etc.) I was informed that they reduced or even stopped working on that problems. Therefore I am wondering - does IDS is still being researched in scientific (academic) community? Is yes, could you give me some hints to the places where it is being researched and what are hot topics nowadays? Thank you very much!

Regards, mark
