OverviewAI-generated summary
Raghu H. Ramakrishnaiah's research focuses on the intersection of maternal health, neonatal brain development, and neuroimaging techniques. His work investigates how factors such as maternal anxiety, depression, and adiposity during pregnancy can influence white matter development and functional connectivity in newborns. Ramakrishnaiah has explored the impact of specific medical conditions, such as congenital heart disease, on white matter injury in neonates and has utilized diffusion tensor imaging (DTI) and amplitude-integrated electroencephalography (aEEG) to assess brain health in critical illness.
His publications also examine predictors of outcomes in conditions like posterior reversible encephalopathy syndrome and explore the relationship between DTI of white matter in newborns and subsequent neurodevelopmental outcomes. Ramakrishnaiah leads a research group and has a publication record of 99 papers, with an h-index of 20 and over 1,000 citations. He collaborates with researchers primarily within the University of Arkansas for Medical Sciences, including Sateesh Jayappa, Charles M. Glasier, Paul H. Phillips, and Venkatram Krishnan.
