The central theme of research in our group is the development of novel chemical imaging technology and structures that can be employed to detect, diagnose and understand tissue structure and cancer pathology. These biological sensors may be optical (spectroscopic imaging), material (probes) or computational and physical models. Another major theme is the development of novel instrumentation approaches to fast, high fidelity infrared spectroscopic imaging and development of novel algorithms for information extraction from large imaging data sets.
