Peejay is a PhD Candidate with the Hazards Research Group (HRG) at the School of Geosciences. She holds a Bachelor of Science in Geology from the University of the Philippines and a Master of Science in Geology from the University of Canterbury in Christchurch, New Zealand.

Her research topic entitled “ Geological and Social Dimensions of Volcanic Hazards and Risk Assessment/ Management: Taal Volcano, Philippines as a Case Study” intends to blend physical/geological and social dimensions of hazard and risk assessment and management of volcano-related phenomena, with Taal Volcano, Philippines as a case study.

Part of the research entails ashfall modelling using various ashfall models including Python Fall3D (PF3D) and TEPHRA2 to determine potentially threatened communities from ashfall impact, field validation of results, collection/development of exposure database needed for risk assessment, gathering participant observations and perspectives including semi-structured interviews, questionnaire surveys, and a participatory workshop intended for capacity-building through education and preparedness and other initiatives leading towards DRM policy formulation for hazards related to Taal Volcano.

Her research is supported by AusAID.
Peejay has a vast experience dealing with volcano and earthquake crisis in the Philippines. She is currently a Supervising Science Research Specialist/Geologist of the Philippine Institute of Volcanology and Seismology (PHIVOLCS) in the Philippines.

She has conducted various volcanic and earthquake hazard mapping, assessment and management, and several quick response team investigations of several earthquake- and volcano-related emergency activities including the 1991 eruption and subsequent lahar occurrences at Pinatubo Volcano, Philippines and several eruptions of Mayon Volcano in the Philippines.
