Archaeology

Archaeology was the scientific discipline of excavating, studying and learning from the past.

When the Second Doctor was on Telos he was referred to as an archaeologist. (DW: The Tomb of the Cybermen) The Fifth Doctor's companion Peri Brown had at least a passing interest in archaeology (DW: Planet of Fire) Another companion, Bernice Summerfield, was by trade an archaeologist before she met the Seventh Doctor, and had a supposed degree qualifying her as a professor in it, though not an official one. (NA: Love and War) Bernice specialised in archaeological studies after they parted. River Song held a doctorate on the subject from the Luna University. The Eleventh Doctor implied that people intent on finding him pursued the discipline of archaeology. (DW: Let's Kill Hitler)
