Each school at KTH has local PhD student representatives. They are organized in PhD Student Councils and one student is elected Chairperson for the local PhD Student Council.
ABE PhD Student Council
ITM PhD Student Council (this one acquires the old ECE PhD Student Council too)
The student representatives for the PhD programs are called PADs (Program representative PhD student). Each PAD is connected to their respective PhD program. A school can have one or more PhD programs, therefore one or more PADs.
