Bio
Dr. Joseph is a Caribbean volcanologist involved in the study of emissions (gas and waters) associated with active volcanic systems. She has been associated with the Seismic Research Centre (SRC) for the past 17 years, first as a graduate student and then as a member of staff. Dr. Joseph also provides scientific and administrative support in monitoring efforts at the Montserrat Volcano Observatory (MVO) including Duty Scientist, Ground Deformation Monitoring, Dome Volume Monitoring, and Gas Monitoring. At the SRC she is responsible for the geothermal monitoring program, which involves the collection and analysis of volcanic gases and geothermal waters in the islands of the Lesser Antilles, and its application to monitoring changes in volcanic activity. Her other research interests include study of the hazards and impact of persistently degassing volcanoes and the use of low-cost technology for the monitoring of volcanic emissions; and the behavior of the magmatic component in volcanic gases.
