Profile Summary

Wonsang You received the M.Sc in signal processing from the Korea Advanced Institute of Science and Technology (KAIST), Daejeon, South Korea, in 2008, working on object detection and motion tracking in image sequences. From 2009 to 2012, he had worked for statistical modeling of resting state functional MRI (rs-fMRI) as a researcher in Leibniz Institute for Neurobiology, Magdeburg, Germany. In 2013, he obtained the Ph.D. degree in electrical engineering and information technology from Otto-von-Guericke University, Magdeburg, Germany. With his dissertation, he suggested a long memory model of rs-fMRI that theoretically describes the physical relationship of fractal behavior with functional connectivity in rs-fMRI.

His research interest is to figure out the early development of functional brain networks through computational neuroimaging data analyses and to develop its clinical applications for pediatric diagnoses. His specialties include resting state brain connectivity, fractal and wavelet analyses, statistical time series analysis, computational neuroscience, pattern recognition, and machine learning.

Since 2013, he has worked as a research associate in the Advanced Pediatric Brain Imaging Laboratory at Children’s National Medical Center in Washington D.C.. His current project is to develop analytic tools and data models for in vivo fMRI data of fetal brain and placenta, including fetal motion correction, fetal circulation-based BOLD signal model and resting state functional connectivity of the fetal brain.
