Sirisha Tadimalla Ph.D


I am a Biomedical Engineer and Medical Physicist by training. I completed my PhD in Medical Physics and Biomedical Engineering at Queensland University of Technology in Brisbane, Australia in 2018. My PhD research focused on the study of the collagen fibre network in articular cartilage using MRI techniques, mainly T2 mapping and DTI, and small-angle X-ray experiments (SAXS). I also have a Masters degree by research in Biomedical Engineering from the University of Iowa, USA. I worked as a Graduate Research Assistant in the Orthopedic Biomechanics Lab and my research project focused on the multi-modal assessment of articular cartilage to observe the progression of osteoarthritis using T1rho, T2 and dGEMRIC methods.

I am currently working on the TRISTAN project ( towards developing DCEMRI protocols to quantify hepatocyte transporter function for prediction and assessment of drug toxicity in the liver.

Research interests

My interests lie in clinical application of quantitative MRI methods such as relaxation mapping (T1, T2, T1rho), diffusion-weighted and diffusion tensor imaging (DTI) for quantification of tissue microstructure and function, and dynamic contrast-enhanced imaging (DCE-MRI) for quantification of tissue function.
