Dmitriy A. Yablonskiy, PhD, is a professor of radiology and a principal investigator in the Biomedical MR Center for Mallinckrodt Institute of Radiology at Washington University School of Medicine in St. Louis. Yablonskiy’s work focuses on revealing new biophysical mechanisms underlying MRI signal and using these mechanisms for developing new MRI-based techniques to study biological tissue structure and functioning. Since entering the MRI field, Yablonskiy has authored and co-authored more than 100 peer-review papers in the areas of MRI and physiology that are highly cited. Some of the Yablonskiy Lab’s major achievements include the development of gradient echo plural contrast imaging (GEPCI) and its advance version the genetically-informed quantitative gradient recalled echo (qGRE), in vivo lung morphometry with hyperpolarized 3He MRI, and quantitative BOLD (qBOLD). Yablonskiy has also developed quantitative methods of diffusion MRI, MRI spectroscopy, lipid quantitation in fatty livers, and biophysical theory of brain temperature regulation. These new methods provide safe and non-invasive in vivo biomarkers for monitoring progression of different diseases, thus opening doors to substantially improve diagnostics and perform fast and accurate longitudinal studies for clinical monitoring and research trials. Recent work is focused on applying MRI-based GEPCI and qGRE techniques to link brain genetic and cellular microstructure with brain functioning in healthy people and patients with brain diseases, including Alzheimer’s disease, multiple sclerosis and amyotrophic lateral sclerosis.
