About
Ebrahim is an associate research scientist in the Department of Molecular, Cellular, and Developmental Biology at Yale University. She holds a PhD in Chemical Ecology from the Max Planck Institute for Chemical Ecology and the University of Jena.
Current research
Ebrahim's research focuses on unraveling the secrets of tsetse flies, notorious vectors of African trypanosomiasis. In a recent study published in Science (Ebrahim et al., 2023), Ebrahim and coworkers identified a volatile sex attractant crucial for tsetse fly mating behavior. This finding enhances our understanding of their ecological interactions and opens possibilities for targeted control strategies against the disease. Additionally, she investigates the molecular and cellular basis of olfactory responses to tsetse fly attractants. In a comprehensive study published in PLOS Genetics (Chahda et al., 2019), Ebrahim and coworkers unraveled the mechanisms underlying tsetse fly olfactory responses to specific attractants. By understanding these molecular and cellular processes, her research has the potential to inform the development of novel strategies for tsetse fly control and disease prevention. In a separate study published in Current Biology (Dweck et al., 2022), she gained insights into the neural mechanisms underlying salt preference in fruit flies, shedding light on gustatory perception pathways and paving the way for studying sensory mechanisms in other organisms. Ebrahim also intrigued by the impact of visual cues on sexual behavior. In a study published in Nature Communications (Ebrahim et al., 2021), she explored how sight influences sexual behavior and gene regulation in Drosophila, revealing an accelerated sexual response and up-regulation of a micro-peptide gene in fruit flies. These insights contribute to our understanding of evolutionary adaptations and survival strategies in different Drosophila species.
Future research vision
Ebrahim's research continues to push the boundaries of scientific knowledge in genetics and neurobiology. Through studies on diverse organisms, she aims to uncover the fundamental principles underlying sensory perception, behavioral responses, and evolutionary adaptations.
