Profile


Brief Introduction

I 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, I had worked for statistical modeling of resting state functional MRI (rs-fMRI) as a researcher in Leibniz Institute for Neurobiology, Magdeburg, Germany. In 2013, I obtained the Ph.D. degree in electrical engineering and information technology from Otto-von-Guericke University, Magdeburg, Germany. With my dissertation, I suggested a long memory model of rs-fMRI that theoretically describes the physical relationship of fractal behavior with functional connectivity in rs-fMRI.

My 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. My specialties include imaging data analyses of the brain and placenta, brain connectivity, fractal and wavelet analyses, statistical time series analysis, medical imaging data analyses, computational neuroscience, pattern recognition and machine learning.

Since 2013, I have worked as a staff scientist in the Developing Brain Research Laboratory at the Children’s National Medical Center in Washington D.C. My current project is to develop analytic tools and data models for both in vivo fMRI and diffusion-weighted imaging (DWI) of fetal brain and placenta, including fetal motion correction, fetal circulation-based BOLD signal model and resting state functional connectivity of the fetal brain.

Research Interests

  • Diffusion-weighted imaging (DWI) of the placenta
  • Functional MRI data analyses of the fetus
  • Resting state brain connectivity
  • Statistical time series analysis: fractal and wavelet analyses
  • Neurodynamics: fractality, metastability and self-organized criticality
  • Medical imaging data analyses, computational neuroscience

Personal Activities

When I was young, I had been captivated by mathematics and physics- especially astronomical physics after I read a book "A Brief History of Time" written by Prof. Stephen W. Hawking. In 2002, I worked as a team leader of the "Korea Internet Volunteers" project, introducing information technology (IT) to high school students in Sri Lanka.
