About
Research
Overview
My major research interests include the identification of genetic bases of human diseases affecting the structure and function of the nervous system, and elucidation of underlying disrupted biological processes using multi-omic approaches and patient-derived 2D and 3D induced neuronal systems with a special focus on cerebral cortical malformations, schizophrenia, early-onset neurodegenerative syndromes and migraine. I also work on developing high-throughput omics approaches for early detection and profiling of brain tumors.
