A person who studies or is an expert in coprophagia; also used to describe someone who has a compulsive behavioral interest in feces.
From coprophagia + '-ist' (one who practices or studies). A rarely-used term, as most scientific discussion uses less loaded language like 'fecal ingestion researcher.'
True coprophagists are more common in medical and veterinary research than you'd expect—some very respectable scientists have spent careers understanding why animals eat waste and what it tells us about nutrition and disease.
