A scientist who studies how living organisms, cells, and tissues behave, survive, and are preserved at extremely low temperatures.
From 'cryobiology' + '-ist' (one who practices or specializes in). This professional title emerged in the mid-20th century as cryobiology became an established scientific discipline.
Cryobiologists are the people figuring out how to freeze human organs without damaging them for transplants, and whether bacteria can survive in space—they're literally studying life at the edge of freezing.
