In House M.D., which medical specialty does Eric Foreman lead after becoming department head?

Eric Foreman leads the department of diagnostic medicine after becoming its head in House M.D. Omar Epps portrays Foreman, who begins the series as one of House’s original fellows.

Foreman is a neurologist by training, but his work with House centers on difficult cases that require broad diagnostic reasoning. His career develops from junior doctor to senior hospital leader, and his increasing authority creates professional tension with House’s unconventional methods.

The department’s role is to investigate illnesses that have resisted ordinary diagnosis. It is not the same as a conventional specialty such as cardiology or oncology. That distinction is important because Foreman’s personal specialty and his administrative department are different things.

Foreman eventually becomes Dean of Medicine at Princeton-Plainsboro. The question concerns the department he leads, not his original training: the canonical answer is diagnostic medicine.
