Nabavizadeh Group Research Internets

The Nabavizadeh group studies cross-complimentary approaches to cancer treatment, identifying methods to improve quality of life, reduce toxicity, and increase progression free survival. Our cross-collaborative group partners with other researchers within the department, the Spellman Lab at OHSU, and researchers at other institutions. Current projects range from translational projects involving human subjects, prospective clinical trials, population studies, and meta-analyses.
