Description of Research Expertise

I am a translational researcher with M.D. and a Ph.D. degrees, the last in Biochemistry. I am highly proficient in the noninvasive biomedical applications of nuclear magnetic resonance (NMR). With NMR, I have assessed metabolic and functional variables in isolated cells and perfused organs in vivo, as well as in tissues in situ of whole organisms including humans. The ultimate goal of my research is to test if these NMR-visible variables offer reliable information to improve treatment assignment and follow-up of human diseases, specially cancer.

In regard to cancer, we know that tumors have abnormal levels of phosphomonoesters (PME). Given this, my research team optimized the noninvasive assessment of PME in tumors in situ using phosphorus NMR spectroscopic imaging. A translational contribution of this research is the substantiation of the correlation of the pretreatment PME tumor value with the outcome to first-line therapy in patients with lymphomas. To continue this research, I am proposing to test if this correlation is useful to predict the likelihood of each lymphoma patient to respond to first-line therapy. If this correlation is proven, then the pretreatment PME tumor value can be used in the clinic to risk-assign treatment in lymphoma patients.

My current research has the following six objectives. (1) Improve the quality and quantity of observable variables by in vivo NMR using current technical advances. (2) Improve NMR data analysis using advanced mathematical algorithms. (3) Elucidate the mechanism(s) by which PME tumor values correlate with response to therapy. (4) Optimize the power of PME to predict treatment outcome. (5) Extend the potential predictive value of PME to other cancers. (6) Extend this research to other diseases besides cancer.
