Physiologist

A physiologist studies how living systems function — how organs, cells, and whole bodies work, from nerve signalling to circulation to exercise. Running experiments on tissues, animals, or human subjects, they build the mechanistic understanding that underpins medicine, sport, and biology.

They work in universities, medical schools, and research institutes, and in applied settings like sports science and pharma. The role suits curious, methodical people who like designing experiments to dissect how life actually works.
