Brice Tiret, PhD

Post-doctoral Scholar
Physical Therapy and Rehabilitation Science

I am a post-doctoral scholar in the Physical Therapy and Rehabilitation Science Department at UCSF since January 2017.

My current research involves methodological development of biomarkers of neuro-inflammation using Magnetic Resonance Spectroscopy (MRS). I specialize in in vivo proton and phosphorus single voxel MRS, as well as hyperpolarized 13C Magnetic Resonance Spectroscopic Imaging (HP 13C MRSI) methods.

I received my PhD from the Université Paris-Saclay in France. As a PhD student, I was looking at methodological development for X nuclei NMR spectroscopy with in vivo neurological applications in rodents. Looking at different models of Huntington’s disease, I was interested at pH variations as a biomarker, as well as metabolomics changes measured using dynamic 31P and 13C MRS.
