Steven Stufflebeam, M.D.

Principle Investigator
Director of Clinical Magnetoencephalography, Martinos Center

I received my B.S.E in BioEngineering from the University of California, Berkeley, and my M.D. from the Health Science and TechnologyDivision of Harvard Medical School and the Massachusetts Institute of Technology.  My residency in Diagnostic Radiology was completed at the University of California, San Francisco (UCSF) in the Scholar’s Program, with Board Certification in Diagnostic Radiology.  This was followed by a fellowship in diagnostic neuroradiology at UCSF.  I completed post-doctoral fellowship at the MGH/NMR Center, sponsored by the ISMRM & Nycomed-Amersham.

The purpose of the laboratory is to understand how the brain functions in both health and disease. I’m particularly interested in using non-invasive imaging technology to understand how the brain represents and processes information. My specific research interests include epilepsy, brain tumors, schizophrenia, and computational models directed at understanding functional neuroimaging data.

Research Staff

I received my Ph.D. in Experimental Psychology at CBRU, University of Helsinki, Finland in 2005. In 2006, I started my clinical training in neurology and sleep medicine at Henry Ford Hospital, Detroit (MI). From 2014 to 2018 (February) I was a co-director of MEG laboratory at  Meadowlands Hospital (NJ) where I  was performing the MEG/EEG brain mapping of epilepsy data for per-surgery evaluation. I joined the Dr. Stufflebeam’s lab in 2018, I am interested to use the multimodal imaging (MEG, (f)MRI and high density EEG) for pre-surgery evaluation of epileptic activity as well as localization of functional data for identifying  the sensory- motor – and language areas in patients with epilepsy, including pediatric population. In research field,  I am interesting to learn how brain develops under normal and abnormal circumstances, and how these outcomes can be demonstrated by MEG / EEG/ ERPs/ (f)MRI methods.


Linda Douw, Ph.D.

Post-doctoral Research Fellow at the Martinos Center

I received my MSc in Clinical Neuropsychology at the Free University in Amsterdam, The Netherlands in 2006. After graduating, I continued the research I started during my Master’s on functional connectivity and neural networks in brain tumor patients, at the VU University Medical Center in Amsterdam, using MEG. I finished my PhD on the interplay between cognition, epilepsy and tumor from a network perspective in 2010. In my current research, I hope to use multimodal imaging combined with connectivity and network analysis to first understand more about cognition in epilepsy patients. My second aim is to apply these analyses in theclinical setting of epilepsy surgery.
