Research Interests:
The development and application of advanced in vivo MR imaging techniques to study disease in general. Magnetic resonance imaging (MRI) and spectroscopy (MRS) can be used to monitor the development of chronic fatal conditions, such as hepatocellular carcinoma (liver cancer) spongiform encephalopies, or Alzheimer's disease. MRI and MRS are non-invasive techniques and can be used to identify biomarkers for disease. This information could potentially be used to test novel drug treatments. Research at the National Research Council Institute for Biodiagnostics (NRC-IBD) focuses on the development and commercialization of innovative medical devices and technologies for the non-invasive diagnosis of diseases in humans and animals. NRC-IBD research is based on various imaging and spectroscopic modalities, prototyping, biomedical informatics, and medical software. NRC-IBD offers collaborative opportunities in the medical device, biotechnology and pharmaceutical industries
