Summary

I'm an SM student in Polina Golland’s Medical Vision Group in CSAIL at MIT. Currently, we're investigating representations of functional MRI time series and their associated networks in the brain. Of particular interest is capturing connectivity abnormalities in patients with epilepsy.


Previously, I worked on DTI registration with Xavier Pennec in Projet Asclepios at INRIA Sophia Antipolis. Before that, I completed an MSc in Computer Graphics, Vision and Imaging at University College London, where my thesis covered research on multiple fibre reconstruction methods with Daniel Alexander in the Microstructure Imaging Group.
