Briefly About Ozlem

Bees play a vital role as a crucial part of our ecosystems and are essential for the sustainability of agriculture. Ozlem Gonulkirmaz Cancalar’s focal point during her Ph.D. has been to generate mutant lines in bumble bees to investigate the behavioral influence of canonical circadian genes. Thanks to the prestigious Marie Sklodowska-Curie program, she received advanced training in renowned labs in Würzburg, Germany, and Ceske Budejovice, Czech Republic. In these labs, she honed her skills in immunostaining and developing CRISPR techniques in different insect species, such as Drosophila and Firebug.
With these skills, Ozlem successfully developed a CRISPR/Cas9 system for the non-model organism Bombus terrestris, creating a clock mutant bee for the first time. This groundbreaking project required significant resilience and perseverance, as it was the first instance of gene editing in a bumble bee.
Starting this fall, Ozlem will be joining the University of Würzburg in Germany as a postdoctoral researcher. While she has developed expertise in molecular and behavioral disciplines, her future focus will be primarily on neuronal mechanisms.

The Marie Sklodowska-Curie grant is a highly esteemed honor, providing exceptional opportunities for researchers to advance their careers through international training and collaboration. This grant is known for its competitive nature, recognizing and supporting only the most promising researchers across Europe. Being awarded this grant not only signifies excellence in research but also opens doors to unparalleled academic and professional development, making it a highly prestigious achievement in the scientific community.

First gene editing and circadian rhythm with CRISPR in bumblebees

Bees play an indispensable role in our ecosystems and are vital for the sustainability of agriculture. However, bee populations face numerous threats. Innovative gene-editing techniques like CRISPR offer promising solutions for enhancing bee health and adaptability.
Circadian rhythm regulates many physiological and behavioral processes in various organisms. In bees, it directly influences time management for optimal flower yield, sun-based navigation, social synchronization, and task organization within the colony. The bumble bee, Bombus terrestris, serves as an excellent model for studying the impact of clock genes on behavior due to its small colonies and relative ease of laboratory maintenance compared to honey bees.
In her doctoral research, she was the first to characterize a set of complex behaviors regulated by the circadian rhythm in bumble bees. Additionally, She pioneered the use of the CRISPR/Cas9 gene-editing system in bumble bees to mutate a clock gene.
