Research focus

Biology of brain tumors; mechanisms underlying invasion of gliomas and meningiomas; evaluations of lipopolysaccharide as an antitumoral agent. Assessment of tumor growth upon brain function; MRI imaging of brain tumors. Additionally, Dr. Chicoine is a clinical research investigator pursuing novel treatment strategies for brain tumors through ongoing clinical trials. Furthermore, advanced intraoperative magnetic resonance imaging (iMRI) strategies are being explored for brain tumors, Chiari malformations, and other neurological diseases using the newly installed high-field strength iMRI operating rooms at Barnes-Jewish Hospital.
