My research focuses on evidence based radiation oncology and the development of novel strategies for optimizing radiation therapy outcome through personalized prescriptions of the 4D dose distribution using molecular risk profiling and functional imaging, so-called theragnostic radiation oncology. Theragnostic radiation oncology is the theme for a NIH PO1 program project grant under development that I am coordinating. The aim is to provide the clinico-biological basis for rational prescription of non-uniform dose distributions in individual patients. The UW provides an exceptional environment for pursuing this research line, with strong functional and molecular imaging groups - expected to be further enhanced when the Interdisciplinary Research Center (IRC) comes on line.
Molecular risk profiling is directly linked with outcomes research, mainly based on data from clinical trials and we have pioneered the use of hierarchical clustering and competing risks analysis in this context. Most of our work so far, has been based on immunohistochemical markers or DNA gene expression arrays, but we are actively pursuing collaborations and seeking funding for expanding these approaches into proteomics and metabolomics together with the Biotech Center at UW.
My third major research area is bioeffect modeling and outcomes research. Bioeffect modeling includes the modeling of dose-response relationships, linear-quadratic time-dose-frationation models and NTCP/TCP models. I am also involved in the design, conduct, analysis and interpretation of several randomized controlled trials and have a long-standing research interest in long-term side-effects, health-related quality of life and functional outcomes. Active research lines also include surrogate endpoint in clinical trials and normal tissue radiobiology. Much of this research is pursued with a large network of national and international collaborators.
