Research Description

My research has been directed at biological actions of neuronal growth factors and signaling mechanisms downstream of receptor tyrosine kinases. Recently, we have focused on functions of the RAF/MEK/ERK signaling cascade in brain development. Mutations in core pathway components as well as in upstream modulators are associated with variety of neurodevelopmental syndromes collectively known as “Rasopathies”. Our findings have implications for understanding mechanisms of cognitive dysfunction in “Rasopathy” patients and potentially for developing new treatments.
