Benoit Driesschaert, Ph.D.


   Dr. Driesschaert holds a Ph.D. from the Université catholique de Louvain (UCL) Belgium. His Ph.D. focused on the development of EPR spin labels (with Pr. Bernard Gallez and Pr. Jacqueline Marchand-Brynaert). In 2014, he moved to the Ohio State University, USA, to expand his knowledge in EPR spectroscopy (with Pr. Jay Zweier and Pr. Valery Khramtsov). Recently, Dr. Driesschaert  has been awarded a NIH K99/R00 pathway to independence grant from the NIBIB (2017/2022) to launch his own research programs. He is now leader of the synthetic development of the EPR/NMR probes of the IMMR center and Research Assistant Professor at the Department of Pharmaceutical Sciences.

The sphere of interest:

   Benoit has an extensive experience in the development of stable triarylmethyl (trityl, TAM) radicals used to measure important parameters of the tumor microenvironment such as oxygen, pH, inorganic phosphate or enzyme activity by magnetic resonance imaging and spectroscopy. He is using organic chemistry, organic electrosynthesis, flow chemistry and photocatalysis. He is also interested in the development of new technique of in vivo spin trapping.
