re: Does anyone know if Demetris Robertson is on campus at Cal

From an international perspective, Cal-Berkeley is essentially one of the world's top 10 institutions.

Shanghai Jiaotong Rankings (China):
Cal - 4
Georgia - 151-200

Times Higher Education Rankings (UK):
Cal - 13
Georgia - 251-300

CWUR (Saudi Arabia):
Cal - 7
Georgia - 204

As a disclaimer, UGA tends to underperform in these rankings for two reasons: 1) Georgia Tech has the "prestige" engineering departments and 2) the lack of a med school.
