Education Johns Hopkins University, Baltimore, MD, USA PhD in Electrical and Computer Engineering, 2009 Johns Hopkins University, Baltimore, MD, USA MSE. in Electrical and Computer Engineering, 2006 Cairo University, Giza, Egypt M.Sc. in Systems and Biomedical Engineering, 2003 Cairo University, Giza, Egypt B.Sc. in Systems and Biomedical Engineering, 2000
Research Interests: My main research interests are in in vivo magnetic resonance imaging (MRI) and spectroscopy (MRS) including: · MRS quantifications techniques · Pre- and post-processing strategies to enhance the signal to noise ratio (SNR) in cardiac proton and phosphorus MRS · Chemical exchange and saturation transfer MRS · Fast imaging of MR relaxation parameters · Cardiac MRI · Cardiac energetics · Diffusion-weighted MRS I am also interested in reconstruction methods in MRI and MRS including: · Gridding · Partial k-space methods · Dynamic imaging · Parallel imaging · Suppression of ringing, motion and off-resonance artifacts
