Research Projects
The primary focus of my lab is developing new image analytics, radiomics, and machine learning schemes for imaging data. The key innovation lies in handcrafting and designing unique tools that can capture biologically relevant and clinically intuitive measurements from routinely acquired imaging (MRI, CT, PET). Further, by conducting cross-scale associations between imaging, pathology, and -omics through multimodal fusion, these tools can “unlock” the information captured by different data modalities.
Applications of our tools are being examined in:
- Computer-aided diagnosis & disease characterization
- Decision support for treatment (e.g. choice of therapy) and targeting therapeutic procedures
- Quantitative evaluation of response to treatment in vivo
This multi-disciplinary, multi-pronged approach is being applied to colorectal, renal, and prostate cancers, as well as digestive diseases.
