Rosalind J. Sadleir, PhD

sadleirResearch Assistant Scientist, Department of Biomedical Engineering

Rosalind Sadleir, PhD is a faculty member in the J. Crayton Pruitt Family Department of Biomedical Engineering at the University of Florida and a Visiting Professor at Kyung Hee University, South Korea.  Dr Sadleir’s research is concerned with modeling and measuring the effects of electricity on the body; and methods of imaging neural activity and other physiological changes using electrical imaging methods.  The NIH and the US Army Medical Research and Materiel Command have funded her research into detection of active bleeding in the ventricles of newborns and peritoneal cavities of blunt trauma victims.

She is currently investigating the effects of transcranial DC electrical stimulation (tDCS) on language.  Dr Sadleir is active in professional societies and as a reviewer, and was the Chair of the joint XIVth International Conference on Electrical Bioimpedance and 11th Conference on Biomedical Applications of Electrical Impedance Tomography, held at the University of Florida in 2010.

With the Center for Movement Disorders & Neurorestoration, Dr. Sadleir is studying the mechanisms of the current generated by Deep Brain Stimulators.

Research Interests:

  • Noninvasive methods of bleeding detection
  • Magnetic Resonance Electrical Impedance Tomography for direct detection of neural activity
  • Modeling the effects of ‘subthreshold’ electrical currents delivered to the scalp (tDCS).
  • Mechanisms and distributions of currents used for Deep Brain Stimulation
