I have a number of unrelated research interests but will outline the main 3.  My mine research focus involves the use of quantitative imaging techniques to assess vascularity in tumors undergoing therapy.  I have focused on contrast ultrasound and dynamic contrast CT as the 2 modalities with which to do this.   Although my previous work in this area has mostly involved rodent models, I am redirecting toward using clinical large animal models of spontaneous neoplasia as a translational mechanism to mainstream these techniques into people.

I also have a strong interest in functional imaging using fluoroscopy.  The 2 areas where I have built a reputation for myself are videofluoroscopic esophagography and fluoroscopic assessment of airway collapse.  Many of my more recent publications have been in these areas and I anticipate continuing in these directions in the future.
