Dr. Araks Martirosyan
ABI Remote Supervisor
Dr. Araks Martirosyan is a postdoctoral researcher in the Laboratory of Glia Biology at the VIB-KU Leuven Center for Brain and Disease Research (Belgium). After Finishing her B.Sc. in the Faculty of Physics at Yerevan State University (Armenia) and M.Sc. in Applied Physics at Cergy-Pontoise University (France), she became interested in the application of Statistical Physics to Biology and chose Computational Biology as her future research direction.
Dr. Martirosyan received her Ph.D. from the Sapienza University of Rome (Italy) in 2016. Shortly after she joined the VIB-KU Leuven Laboratory of Glia Biology headed by Prof. Matthew Holt, where she investigates the molecular heterogeneity of astrocytes – a major non-neuronal cell type in the brain, whose therapeutic potential is largely overlooked. Combining cutting-edge single-cell RNA-seq and novel spatial transcriptomics technologies, Dr. Martirosyan was amongst the first to describe unique astrocyte subtypes in the brain. The goal of her current work is to understand how these subtypes respond to injury and/or disease.
Araks Martirosyan supervised ABI student Arabo Apresyan on a project analyzing developmental neuroscience and single-cell transcriptomics.
