Venkatagiri “Giri” Krishnamurthy, Ph.D., is a Research Scientist with the Department of Veterans Affairs, and a Research Associate in the Department of Neurology at Emory University. Dr. Krishnamurthy received his Bachelor’s and Master’s degree in Electrical Engineering, and completed his doctoral work from the joint program of Bioengineering at UT Arlington and UT Southwestern Medical Center in Dallas.  He then pursued two separate post-doctoral training fellowships. The first was from the Dept. of Radiology and Imaging Sciences at Emory University where he focused on developing advanced methodologies to delineate specific brain networks using resting-state fMRI.  The second was from the Atlanta VA and Emory Neurology where he continued to develop neuroimaging tools for rehabilitation sciences. Dr. Krishnamurthy has been developing task and resting-state fMRI analysis methodologies for the past 10 years. His engineering foundation in signal and image processing along with his training and interest in cognitive neuroscience and cerebrovascular physiology has put him in a unique position to develop sophisticated data analysis tools and methodologies to enhance our understanding of brain functioning in neurotypical and pathological/neuro-degenerative conditions. He currently has a VA RR&D funded Career Development Award that is focused on developing multi-modal neuroimaging methodologies to study longitudinal aphasia recovery. As an integral member of the Atlanta VA Center for Visual and Neurocognitive Rehabilitation (CVNR) Neuroimaging Core, Dr. Krishnamurthy’s expertise in MR protocol design, sequence optimization, and design and implementation of analysis pipelines has led him to serve as a co-investigator on several VA funded rehab studies.

Research Interests:

  • Multi-modal imaging to delineate the neural and vascular dynamics in early stroke recovery
  • Quantifying correlates of spontaneous recovery of language functions in patients with aphasia
  • Combining neuroimaging with brain stimulation (tDCS, vagus nerve stimulation, etc) to delineate brain plasticity and neurocognitive rehabilitation.
  • Investigating the nature of different sources of artifacts (physiological noise and task-correlated motion) in resting-state and task fMRI data, and developing methodologies to mitigate such artifacts
  • Developing neuroimaging tools and approaches to probe into glymphatic functioning.
