Shashwath's CV

 

Who Am I?

Shashwath Meda completed his Bachelor of Engineering in Electrical and Electronics from India. Following his Bachelors he obtained an advanced degree 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 and currently holds the position of a senior clinical data analyst. As part of his job he serves as a liaison between PIs and multiple projects involving complex data/imaging analysis. His major interests include 1) Assessing genotype-phenotype relationships using univariate and multivariate imaging techniques in psychiatric populations 2) Connectivity analysis in cohorts with major neuropathology 3) Exploring brain function and morphology in substance abuse groups.

Currently Active Projects

  • Identifying the role of genes on brain function and morphology in healthy, substance abuse and other psychiatric illnesses.
  • Influence of alcohol on driving - Investigating the functional brain circuitry and localization using ICA and SPM.

Grants

Harford Hospital New investigator grant - Characterizing the Dyslexia Phenotype using Genetics and MR Morphology 
Role: Primary Investigator
