Robert J. Griffin

Robert J. Griffin serves as Professor in the Department of Radiation Oncology at the College of Medicine, University of Arkansas for Medical Sciences (UAMS), focusing on translational research to enhance cancer treatment efficacy through physiological modulation.

Education:

• Ph.D. in Biophysical Sciences (1998, University of Minnesota)
• B.A. in Biology/Music (1991, St. Olaf College)

Research Focus: His laboratory investigates molecular mechanisms of radiation-thermal sensitization, tumor blood flow modulation, and oxygenation dynamics to develop predictive biomarkers. Key initiatives include:

• Thermal therapy biology for radiosensitization
• Angiogenesis/oxygenation modulation via carbogen and hyperthermia
• Molecular targeting of radiation-induced vascular changes
• Translational studies advancing clinical radiation standards

Current work integrates nanotechnology and molecular imaging to exploit tumor hypoxia.

Publication Trends: Spanning 1996-2015, Griffin's work evolved from foundational tumor physiology (pO2 modulation, hyperthermia) to advanced molecular targeting (galectin-1, nanoparticle-TNFα conjugates). His research consistently bridges basic mechanisms—like vessel normalization with angiogenesis inhibitors—to clinical applications, emphasizing hypoxia imaging and synergistic radiation combinations.

Research Infrastructure: Leads an active laboratory at UAMS investigating radiation-thermal interactions, with ongoing projects in tumor vasculature targeting and molecular imaging of hypoxia.
