    Bio I am interested in developing quantitative imaging methods to characterize the tumor microenvironment, and to subsequently relate these imaging parameters to biomarkers that can be used for cancer diagnosis and treatment monitoring. Although multi-modal approaches are of great interest, to date, I have primarily focused on quantitative ultrasound methods with algorithm developments in volumetric power Doppler quantification, ultrasound spectroscopy and contrast-enhanced ultrasound. I am also deeply interested in therapeutic applications of ultrasound where forces (arising from microbubble contrast stimulation) activate mechanotransduction pathways. My current research is focused on developing volumetric contrast-enhanced quantitative ultrasound methods to characterize tumour vasculature and to assess treatment response in patents with colorectal cancer metastases in the liver. I am also leading a project to use ultrasound spectroscopy to diagnose early HCC.
