1Center for Environmental and Nuclear Research, SRM Institute of Science & Technology, Kattankulathur, India.
Abstract:
Peggy Olive from the British Columbia Cancer Research Center in Canada is credited with the development of a method to measure DNA damage in individual cells based on the technique of microelectrophoresis that she named the 'comet assay'; a well-accepted method to measure DNA damage, hypoxia and apoptosis. A multifaceted person and an ardent campaigner of environmental issues, Peggy has contributed significantly to several areas of radiobiology related to the treatment of cancer, her expertise being tumor hypoxia and gamma H2AX foci as a biomarker in radiotherapy.
