Olga Kubrak

Olga Kubrak serves as an Assistant Professor in the Department of Biology at the University of Copenhagen, specializing in the Cell and Neurobiology research section. Her work bridges molecular neuroscience and metabolic physiology through innovative use of Drosophila models to investigate gut-brain communication pathways.

Her primary research explores how gut-derived hormones—including tachykinin, Allatostatin C, and Somatostatin—orchestrate feeding behavior, nutrient selection, and metabolic adaptation. This work reveals conserved mechanisms where hormonal signals from the gut modulate neural circuits controlling sugar appetite, protein craving, and lifespan determination. Current investigations focus on tissue crosstalk between adipose, muscle, and neural systems during dietary stress, with implications for obesity and diabetes research.

Analysis of her publication trajectory shows increasing mechanistic depth in neuroendocrine regulation, evolving from behavioral phenotyping (2022) to molecular dissection of tissue communication networks (2024-2025). Her research consistently targets evolutionarily conserved pathways relevant to human metabolic disorders, with strong emphasis on Drosophila as a discovery platform for fundamental biological principles.
