  • Director, Center for Molecular Caperone/Radiobiology & Cancer Virology
  • Professor, Radiation Oncology

706-721-8759

Dr. Mivechi's primary focus of research in her laboratory, over the past two decades, has been to investigate the regulation and function of mammalian heat shock transcription factors (HSFs) (HSF1, HSF2, HSF4) in the cellular stress response. A second, more recent focus has been to study the cellular processes via which organelle-specific molecular chaperones (cytosolic, mitochondrial and endoplasmic reticulum-resident heat shock proteins) mediate the host response to environmental stressors and the role of these processes in human diseases including cancer.
