Renuka Sriram, PhD

Associate Researcher


My research interests are primarily focused on the application of Magnetic Resonance technology to characterize the underlying metabolic dysregulation in pathologies and use them to develop clinically relevant markers for diagnostic and therapeutic purposes. Specifically, I’ve been engrossed with the application of hyperpolarized dissolution dynamic nuclear polarization MRI technique to urologic cancers; renal cell carcinoma and prostate cancer. Recently I've been exploring the differential metabolism of bacteria to develop specific imaging biomarkers infectious disease.
