Alkis Hadjiosif

Alkis Hadjiosif joined BLAM in December 2015 as a postdoctoral fellow.alkis_4

Alkis received his undergraduate degree in 2008 from the National Technical University of Athens (Electrical and Computer Engineering), after which he moved to Harvard University. There, he worked under the supervision of Professor Maurice Smith, obtaining an MSc in 2011 and completing his PhD in 2015.

His research focuses on the mechanisms for the acquisition and retention of motor memories and skills in both healthy individuals and patients with neurological disease, especially stroke. Alkis’s goal is to leverage insights about these mechanisms to benefit assessment and rehabilitation of neurological disease.
