Oxygen Guided Hypofractionated Radiotherapy for Gliomas
The overall goal is to demonstrate that the efficacy of the hypofractionated radiotherapy can be significantly enhanced by irradiating at times of optimal tumor oxygenation and that the use of hyperoxic therapies in conjunction with hypofractionated radiotherapy can be optimized by use of the information on oxygen levels in the tumors.

Effect of a PARP inhibitor on tumor oxygenation and growth
Poly (ADP-ribose) polymerase (PARP) is a nuclear enzyme that signals DNA damage to repair proteins by synthesizing ADP-ribose polymers on the nuclear proteins. Consequently, inhibition of DNA repair by PARP inhibitors might enhance tumor cell death during chemotherapy and radiotherapy. The goal is to investigate the effect of a PARP inhibitor on the tissue oxygenation and growth of the gliomas when treated alone or in combination with chemotherapy.

Oximetry-guided optimization of chemoradiation for gliomas
The overall goal is to enhance therapeutic outcome of glioma by efficaciously combining DNA damaging agents (gemcitabine and/or radiation) with SCH900776, an inhibitor of cell cycle checkpoint kinase 1 (Chk1). This will be achieved in part through an increase in the tumor pO2 (partial pressure of oxygen), which will further increase the efficacy of chemoradiation. The changes in the tumor pO2 are likely to provide an early indication of tumor response to therapy.

Development of EPR and NIR Oximetry for Diabetic Foot
The major goal of this project is to develop and apply two emerging techniques - Electron Paramagnetic Resonance (EPR) and Near Infrared spectroscopy (NIR) for oximetry to characterize and follow tissue oxygenation in the diabetic foot and provide data that can improve the management of the serious and widespread complication of peripheral vascular disease.

Monitoring Oxygen Repeatedly for Hypoxic Tumor Therapy
The overall goal of this project is to demonstrate, under realistic conditions, that in vivo EPR oximetry can provide repetitive data on tumor oxygenation during the course of therapy and that this can be used to enhance therapeutic outcome.
