Scientific Interest(s):

Dr. James Tomlinson’s research is focused on developing novel engineered antibody fragments as targeting agents against pancreas cancer. He hopes to first translate these antibodies as imaging agents and then secondarily develop these same agents into radioimmunotherapeutics. Additionally, he is involved in collaborations regarding nanoparticle targeting and in vivo click chemistry reactions to enhance targeted therapies.
