This research will focus on developing advanced magnetic resonance imaging (MRI) and biomagnetic sensing techniques. Research topics include 1) characterizing novel nanomagnetic contrast agents on both the macroscopic scale using NIST NMR/MRI systems and on the nanoscale using scanned probe imaging systems, 2) combining low-field MRI with neural sensing using low field atomic magnetometers, and 3) developing benchtop microMRI systems with novel point-of-use hyperpolarization.  The contrast agent work will involve cleanroom fabrication of functional nano-agents based on spintronics concepts and characterizing them in the NIST variable field microMRI. The low field imaging/sensing work involves setting up atomic magnetometer neural sensing systems with associated AI analysis and then working to integrate with a low field MRI system for spinal imaging.  The hyperpolarized microMRI work will focus on developing benchtop imaging systems for biopsies and organoid growth.  The primary focus will be on optimizing the integrated hyperpolarizer, gradient system, FPGA based imaging console, and bioreactor functionality.
