Research Interests

Helical Tomotherapy

Commissioning and validation of this novel treatment and imaging device which combines techniques from spiral CT scanners with linear accelerators thus enabling new radiotherapy processes.

Inverse-planned Intensity Modulated Radiotherapy

Investigation of different inverse planning algorithms as far as convergence, quality and deliverability of solutions.

Outcome Analysis

quantification of tumor control and outcome complications as a function of dose delivered over a course of treatment. This requires the establishment of a dose-volume-time and outcome-complication-quality_of_life database.

Modeling

Dose calculations, biological models, outcome analysis, error propagation.
