Professor in Molecular Developmental Biology
My research group is localized at the department of Cell and Molecular Biology and at the Stockholm Branch of the Ludwig Institute for Cancer Research, where I am also the director.
The vast complexity of the central nervous system raises challenging questions concerning the specification and differentiation of specific types of neurons. Dopamine neurons are clinically important cells that degenerate in patients with Parkinson’s disease and are also implicated in other neurological and psychiatric conditions.
My group is interested in unraveling the signaling and transcriptional regulation that govern the specification, differentiation and maintenance of these cells. The studies have resulted in the identification of several transcription factors with key roles in these processes. The projects are focused on understanding functions in both early specification events and in maintenance of dopamine neurons in the adult brain. Moreover, we are also interested in regenerative medicine in relation to Parkinson’s disease and other brain disorders.
