Who Am I?

Shashwath Meda completed his Bachelor of Engineering in Electrical and Electronics from India. Following his Bachelors he went on to complete his Masters in Biomedical Engineering from Wayne State University (Michigan) in 2005. During his graduate career, he was part of the MR Research Facility (Detroit Medical Center) involved in active research on presurgical functional mapping and development of novel MR biomarkers for TBI (Traumatic Brain Injury), under the dual mentorship of Dr. E. Mark Haacke and Dr. Randall. R. Benson.

Early 2006 he joined The Olin Neuropsychiatry Research Center as a Senior Research Assistant (COBBRA Lab) and currently serves as a liaison between PI’s and multiple projects involving complex data/imaging analysis. His major interests include Imaging Genetics, Novel functional/structural imaging and Connectivity analysis in populations with major neuropathology.

Current Projects

  • VBM based SNP correlates of whole brain structural morphology in Healthies, Relatives of SZ and Schizophrenics.
  • Influence of alcohol on driving - Investigating the functional brain circuitry and localization using ICA and SPM.
  • Exploring and comparing working memory models using Dynamic Causal Modeling in healthy and psychiatric populations.

Grants
