A scientist or specialist who studies algae, or someone who works with algae in research or industrial applications.
From 'alga' (seaweed/algae) with the suffix '-ist' (one who studies or practices). This occupational term developed in the 20th century as algae research became an established scientific field with dedicated researchers.
Algists are discovering that algae might be the key to solving global problems—some are engineering algae to produce biofuels, others are growing it to capture carbon dioxide from the air, and some are even developing it as a sustainable protein source!
