Additional Information


I am a cognitive neuroscientist / neurophysiologist with the goal to
better understand the healthy human brain and to diagnose and treat
neurological and psychiatric disorders. To this aim, I use multimodal
combinations of several noninvasive and safe techniques that reveal
different aspects of brain function and structure
(TMS-MEG-EEG-fMRI-MRI-DSI-behavioral measurements).

I am
particularly interested in neuronal implementation of sensory-perceptual
and cognitive functions and how these go askew in clinical disorders.
Specifically, I am mapping neuronal activation trace lifetimes in health
and in schizophrenia, depression, and ADHD, and studying how their
abnormalities may cause symptoms. I am also investigating new biomarkers
for depression, and examining basic mechanisms and potential TMS
treatments of PTSD and anxiety. Another longstanding, physiologically
more basic, interest of mine lies in how large-scale integration over
multiple human brain systems occurs (multisensory and sensorimotor
integration) and how learning influences it.

To reach the above
goals I also develop novel techniques. Much of my present methodological
work focuses on utilizing electromagnetic modeling to improve TMS
navigation such that its accuracy and therapeutic efficacy could be
improved. I am also involved in developing methods for modeling dynamic
interactions between areas (spatiotemporally accurate Granger causality)
and constructing new types of TMS multichannel arrays.

I am the TMS Core Director at the MGH/MIT/HMS Athinoula A. Martinos Center for Biomedical Imaging.
