Tibebe Dejene Biasazin

Tibebe Dejene Biasazin
I hold a Ph.D. degree earned in 2017 and have since embarked on a dynamic research career. I have undertaken postdoctoral assignments, showcasing my commitment to advancing scientific knowledge. My accomplishments include securing two grants as a principal investigator and one as a co-applicant. Furthermore, I have played an instrumental role in nurturing future talent within academia by serving as a co-supervisor for numerous master's students. Currently, I am actively co-supervising three Ph.D. students, contributing to the advancement of our field.


I am actively involved in research within the field of chemical ecology, with a specific focus on tephritid fruit flies. In this inquiry, I am dedicated to uncovering the distinctions in sensory mechanisms between males and female tephritid fruit flies. My primary objective in this area of my research is to develop a highly efficient attractant tailored to female  tephritid fruit fly pests.

Additionally, my research extends to the intricate interactions between ants, aphids, and their natural predators. I am dedicated to investigating these complex ecological relationships. My work encompasses the disruption of ant-aphid mutualism through the application of volatile compounds, with the overarching goal of enhancing the ecological services of natural predators.
