Scientific Focus

My group studies the molecular mechanisms involved in the pathophysiology of mental disorders applying cross-species and cross-disorder approaches. We utilize behavioural, molecular, and histological analyses of cell culture and mouse models, viral gene transfer, as well as the genetic and molecular investigation of human biosamples and omics data from human subjects. My group tightly collaborates with psychiatrists, pharmacologists, and psychologists to translate our findings to human patients. With this approach we aim to understand the complex nature of mental disorders and overcome the translational roadblock that hampered the development of new treatments for mental disorders for the last 50 years despite significant advances in the basic neurosciences.



Mouse behaviour, genetic mouse models, maternal immune activation, stress-based animal models, viral gene transfer, human and mouse primary cell cultures, qPCR, Western blotting, immunohistochemistry, morphological analyses, QTL mapping, genetic analyses
