Research Summary

My main area of research interest is calculational dosimetry with an emphasis on superposition/convolution and Monte Carlo methods. I have developed tools using Monte Carlo methods used as input for a superposition/convolution calculation algorithm. This algorithm is a generalization to brachytherapy dosimetry and has applications in investigating the influence of heterogeneity correction inclusion on brachytherapy dosimetry.

I am also interested in megavoltage x-ray image quality assessment and improvement using amorphous silicon flat panel technology. The goal of this research is the improvement of megavoltage image quality such that it could be used for daily image guided radiation therapy via portal images and/or megavoltage cone beam CT.

I am generally interested in image guided radiation therapy including intensity modulation and high dose rate brachytherapy. Specifically, I am involved in a project to investigate the improvement over two-dimensional planar imaging in high dose rate brachytherapy treatments when three-dimensional x-ray CT or MR imaging is used for treatment planning.
