Brain Research Group @ Dartmouth

A multidisciplinary collaboration between clinicians, engineers, and basic scientists dedicated to the improvement of neurosurgical guidance technologies

The Brain Research Group @ Dartmouth is comprised of a multi-disciplinary group of researchers from various schools and departments at Thayer School of Engineering, Dartmouth Medical School, and Dartmouth Hitchcock Medical Center.

The main objective of the Brain Research Group is to investigate and develop new technologies that will aid neurosurgeons during surgical procedures.

The two main projects of the Brain Research Group @ Dartmouth are 1) ALA-induced PpIX fluorescence guided resection and 2) brain deformation modeling.
