Adrian Haith

Co-Director of BLAM LabAdrian Haith

I am an Associate Professor in the Department of Neurology at Johns Hopkins University.

My research seeks to develop and test theories about how the brain makes decisions and controls movement of the body, and how it learns to improve these capabilities through experience.


I received my undergraduate degree from Cambridge University (Sidney Sussex College) in Mathematics and Computer Science. I received an MSc in Machine Learning/Informatics from the University of Edinburgh and subsequent PhD under Dr. Sethu Vijayakumar. I then worked as a postdoctoral fellow with Dr. Reza Shademhr and then in the BLAM Lab under Dr. John Krakauer. I became a Faculty in the Department of Neurology and Co-Director of the BLAM Lab in 2014.
