Research Interests

Novel radiation detectors

This research is focused on the design, fabrication and evaluation of radiation detection and dosimetry systems.  Areas of interest include organic electronic devices and scintillation detectors (organic and inorganic).

4-Pi radiotherapy

Developer Mode on the Varian TrueBeam linear accelerator platform is being used to explore trajectory-based radiotherapy in which the couch, gantry and collimator of the system can be dynamically moved to affect highly compact, conformal dose distributions.

Radionuclide Therapy

We are studying the effects of the composition and size of radiolabeled microspheres used for transarterial radioembolization on the radiation dosimetry of these procedures.  We are developing a framework for fast, accurate, patient-specific dose calculations.
