Kristin Tessmar-Raible

Prof. Dr. Kristin Tessmar-Raible is a faculty member at the Alfred Wegener Institute within the Polar Biological Oceanography department. Her research focuses on chronobiology, marine organism rhythms, and sensory mechanisms in marine environments, particularly using the annelid Platynereis dumerilii as a model organism. She investigates how light (both solar and lunar) influences circadian/circalunidian clocks, hormonal systems, and developmental processes in marine species.

Her work integrates molecular, genetic, and ecological approaches to understand evolutionary adaptations in light interpretation and timing mechanisms. Recent studies emphasize lunar timing systems, photoreceptor diversity, and the interplay between environmental cycles and organismal physiology. She leads projects on circadian rhythms in marine annelids and has developed novel methods for multi-labelling in cellular studies.

Key affiliations include the AWIPEV Arctic Research Base and collaborations with institutions like EMBL and DKRZ. Her research also involves advancing marine genomics and studying the impact of light regimes on neural and stem cell regulation. No specific scientific awards are listed, but her contributions to chronobiology and marine biology are widely recognized in the field.
