Research Interests

Mallar Chakravarty is interested in the anatomy of the brain. His group focuses on how anatomy changes through development, aging, and in illness and how the dynamics of brain anatomy are influenced by genetics and environment.

He leads the Computational Brain Anatomy (CoBrA) Laboratory at the Brain Imaging Centre. His group is a dynamic multi-disciplinary laboratory that is interested the anatomy of the brain and specifically:

  • how it matures through adolescence
  • how it stays healthy through the normal ageing process
  • how alterations in brain anatomy are related to neurodegenerative disorders such as Alzheimer’s and Parkinson’s disease and neurodevelopmental disorders such as schizophrenia.

To do so, he uses and develops sophisticated computational neuroanatomy techniques that are able to automatically parse the geometric complexity of brain anatomy.
