Medicine at the edge
of the thin air.

I am a physician and researcher based in Abha, Saudi Arabia — a city that sits above two kilometres of elevation, which makes the highlands themselves a laboratory for how human physiology responds to reduced oxygen.

My work runs along two threads. The first is experimental: blood-volume kinetics and hematological adaptation to moderate altitude, and what they reveal about oxygen transport and acclimatization. The second is reflective: the ethics of clinical practice and the long history of medicine — including the Arabic and Islamic scholarship that first described diseases we still teach today.
