Projects

 

7T FMRI PROJECT (2019 - Present)

MGH/HMS, Boston, MA

Acquisition of functional MRI data in the 7T scanner and analysis of the data to find differences between subjects with cerebral amyloid angiopathy and healthy subjects.

 

GLOBAL QUANTIFICATION OF STRUCTURAL CONNECTIVITY VIA A CONDUCTANCE MODEL (2017 - Present)

MGH/HMS, Boston, MA

Development of a global method that quantifies structural brain connectivity derived from diffusion MRI, with the use of a conductance model. Detecting structural brain connectivity differences in disease. Here you can find the paper and code.

 

STATISTICAL MODELS FOR FMRI (2013-2016)

Inria, Grenoble and Paris, France

Statistical Models for the coupling of ASL and BOLD Magnetic Resonance modalities to study brain function and disease. It included: the creation of a parcellation of the brain based on hemodynamic features extracted from BOLD fMRI (paper can be found here); the inclusion of a physiological prior to inform a Bayesian analysis of ASL fMRI data (paper can be found here); the comparison of multiple physiological models and parameters in the analysis of ASL fMRI data (paper can be found here); and the development of stochastic and variational solutions to ASL fMRI data analysis (paper can be found here). Codes are available at pyhrf.github.io

 

GP FOR FMRI ANALYSIS (2016)

CEA Neurospin, Inria-Saclay, France

Development of a non-parametric joint estimation method for functional MRI task activation values and the hemodynamic response function (HRF). The HRF was modeled as a Gaussian Process, making continuous evaluation possible. The paper can be found here.
