I am a former PhD. candidate in Dr. Louis Collins' lab in the Brain Imaging Center at the Montreal Neurological Institute.
I completed a post-doctoral fellowship at the Aarhus PET Center (Denmark) under the mentorship of Dr. Albert Gjedde (September 2007-January 2009). I am currently employed by the Allen Institute for Brain Science in Seattle, Washington, USA.

Research Interests

Atlasing for the basal ganglia and thalamus.
Multi-modal image registration, particularly histology-to-MRI registration, and intra-operative electrophysiological recordings to MR
Pre-operative surgical planning techniques involving atlas-to-patient registration
Volumetry of the basal ganglia and the thalamus as it relates to different pathologies
