Scientific Interest(s):

Dr. Percy Lee’s research interests are primarily translational. He has expertise in innovative approaches of delivering radiation therapy; these include intensity-modulated radiation therapy (IMRT), as well as stereotactic body radiation therapy (SBRT) and stereotactic radiosurgery (SRS) where highly focused radiation is concentrated on localized tumors. These approaches minimize radiation to surrounding normal tissue, thereby reducing side effects and improving tumor control. Lee is focused on developing novel functional image-guided radiation therapy approaches and discovering new molecularly targeted anti-angiogenic drugs for cancer therapy. In addition, he is investigating combining molecular targeted therapy with SBRT in a rational and innovative approach with the goal of improving treatment outcomes.
