Research

Bioinformatics and outcome modeling: design and develop large-scale datamining machine/deep learning methods and software tools to identify robust biomarkers of radiotherapy treatment outcomes from clinical and preclinical data using complex systems analysis and machine learning approaches (radiogenomics). Multimodality image-guided targeting and adaptive radiotherapy: design and develop hardware tools and software algorithms for multimodality image analysis and understanding, feature extraction for outcome prediction (radiomics), real-time treatment optimization and targeting. Clinical decision support: develop and design methods and tools for reinforcement machine learning and optimization of decision making for radiotherapy. Medical physics radiation measurement: design and develop new technologies for radiation using optical and acoustics techniques to interrogate radiation response in real time for online targeting and adaptation. Radiobiology: design and develop predictive models of tumor and normal tissue response to radiotherapy (radiogenomics). Investigate the application of these methods to develop therapeutic interventions for protection of normal tissue toxicities.
