Christian Reiss, Ph.D.

Christian Reiss is Research Fishery Biologist and Program Lead with the Ecosystem Science Division. He conducts research on the population dynamics and ecology of Antarctic krill (Euphausia superba) using a variety of field-based approaches. Since 2005, he led annual expeditions to the Antarctic Peninsula. Recently, he led the transition from a ship-based to an autonomous program to conduct this research. His work supports NOAA and the Department of State to manage the krill fishery and Antarctic resources in support of the U.S. AMLR Program Act.
