Dr. Vasiliki N. Ikonomidou

Vasiliki N. Ikonomidou earned the Diploma in Engineering (MSc) degree and the PhD in Electrical Engineering from the Aristotle University of Thessaloniki, Greece, in 1997 and 2002 respectively. Her PhD thesis focused on the development of excitation techniques for magnetic resonance tagging. In May 2003 she joined the intramural program of the National Institute of Neurological Disorders and Stroke (NINDS) of the NIH (Bethesda, MD), as a Visiting Fellow in the Laboratory for Functional and Molecular Imaging, Advanced MRI Section, working under Dr Jeff Duyn in the development of high-contrast anatomical MRI techniques. In May 2006, she joined the Neuroimmunology Branch of NINDS, where she worked on brain imaging, using MRI and PET, in patients with Multiple Sclerosis. Since August 2009, she has been with George Mason University, where she is an Assistant Professor of Electrical and Computer Engineering, and the MRI Physicist of the Krasnow Institute for Advanced Study. Her research interests are in the fields of technical development for MRI, development of multispectral and fusion image processing techniques, and the detection of early stages of white matter neurodegeneration. Dr Ikonomidou has co-authored 19 papers in peer-reviewed journals, and is a member of ISMRM and IEEE.


Dr. Laurence Bray

            Dr. Laurence Bray received her B.S. degree in biological sciences and M.S. degree in bioengineering from Clemson University, SC in 2004 and 2005, respectively. She received her Ph.D. degree in biomedical engineering from the University of Nevada, Reno (UNR) in 2010. She then gained more research and teaching experience as a postdoctoral fellow in the department of computer science and engineering at UNR.

At Clemson, Laurence worked on the development of a novel polymer coated nitinol endovascular stent for restenosis control and drug delivery release. At UNR, she acquired expertise in computational neuroscience by modeling biological neural networks to replicate brain dynamics underlying navigational learning. As a postdoctoral fellow and a research assistant professor, Laurence focused on improving her models and integrating them in a virtual neurorobotic environment to study high-level human behaviors (e.g. navigation). Along with her research, she has taught a computational neuroscience course for both undergraduate and graduate students.

Laurence has recently started a new appointment as a research assistant professor in the department of bioengineering at George Mason University. She continues her research in the field of computational neuroscience working with Dr. Wilsaan Joiner in developing a biologically realistic neural computational model of sensorimotor adaptation. Her main interests are brain modeling, real-time systems, and virtual neurorobotics. She has worked on several projects funded by the Office of Naval Research (ONR), and her research contributions are covered in multiple recent journal and conference publications.
