Research Focus

Traditional imaging techniques predominently evaluate for anatomic distortions. My main area of research involves using novel imaging techniques to evaluate function. In the case of oncologic imaging, I am interested in using novel contrast ultrasound and computed tomography techniques to evaluate tumor blood flow (vascular function). I am also interested in the use of fluoroscopy (real time radiography) to assess esophageal and airway function in companion animals.
