In addition to the day-to-day supervision, PhD students have a Thesis Advisory Committee (TAC) which consists of the leader of the group in which most of the thesis work is being carried out and two other advisors who guide the student during thesis work.
Irrespective of whether the thesis work is being carried out predominantly at the Max Planck Institute for Evolutionary Anthropology (MPI EVA) or Leipzig University (LU) one of the three thesis advisors is a Professor at UL responsible for awarding the PhD degree, another one of the thesis advisors is a group leader at the MPI EVA.
If a PhD student is registered at another university through which they are going to obtain their degree one of the three thesis advisors is a Professor at that other university. After three to six months PhD students typically prepare a written initial report of their thesis project and discuss it with their supervisors. At the end of each year of the thesis PhD students report on their work by giving a seminar within the context of their respective department's seminar series.
