Megan Poorman (Assoc)

Megan Poorman, Ph.D. is a biomedical engineer and NRC postdoctoral fellow in the NIST Magnetic Imaging Group.  Her work with NIST began in 2018 through the University of Colorado Boulder Department of Physics PREP program. She completed her Ph.D. in Biomedical Engineering at Vanderbilt University in the Institute for Imaging Science and Institute for Surgery and Engineering. Her dissertation research developed Magnetic Resonance temperature mapping methods and Magnetic Resonance-guided Focused Ultrasound systems for the guidance of minimally-invasive therapies in artifact-prone regions such as fatty tissues and near metal. Her research with the Magnetic Imaging Group involves validation of quantitative imaging methods and development of novel imaging techniques.

Outside of lab she can be found going up mountains, whether it be via snow, hiking, running, or rock climbing shoe. 

Current Research Projects:

  • Magnetic Resonance Fingerprinting
  • Cellular-scale validation of quantitative MRI 
  • Development of low-field MRI for clinical applications
