Contribution to science community:  

Dr. Hovav Zafrir - Summary of work experience 
  • More than 30 years of diversified governmental research and development experience in analytical and instrumentation as it applies to nuclear material analysis, mineral exploration, earth sciences, environmental monitoring and hazardous materials remediation.
  •  More than 13 years of development experience in remote sensing systems using nuclear, magnetic and electromagnetic techniques, as it applies to geophysics, nuclear emergency response and hazard assessment with special emphasis on real time monitoring of nuclear facility accident
  • Ten years of extensive experience in earthquake monitoring using multidisciplinary sensor technology. This is including radon analysis and magnetism and also using data from complementary technologies, such as geodetic GPS and seismology.
