Ph.D. Atmospheric Science, Macquarie University
M.S. Environmental Science, University of the Philippines, Diliman
B.S. Applied Physics, University of the Philippines, Diliman

Dr. Narisma has a BS in Applied Physics degree and an MS in Environmental Science from the University of the Philippines, Diliman. She finished her PhD in Atmospheric Science at the Macquarie University in Australia  where her research work focused on the impact of land cover change on the Australian climate. After her  PhD, she then joined the Center for Sustainability and the Global Environment (SAGE) at the University of  Wisconsin, Madison as a Research Associate. At SAGE, Dr. Narisma studied abrupt changes in climate, which have significant human and societal impacts, and identified regions of the world where sudden, unexpected, and prolonged droughts occurred during the 20th century.
Dr. Narisma is currently the head of the Climate and Disaster program of the Ateneo Institutue of Sustiainability and is actively involved in a CHED-Phernet funded research program on “Multi-Disciplinary Risk Research Program Towards Holistic Approach on Disaster Risk Analysis for Sustainable Development” in the Ateneo. She is also the Associate Director for Research and the Head of the Regional Climate Systems Program of the Manila Observatory.

Research Interest: 

Dr. Narisma is broadly interested in environmental physics, with special focus on climate systems. Her areas of research include climate change and variability analyses using regional climate modeling and observation data. She also has done extensive research on land-atmosphere interactions and how changes in the biosphere through land use and land cover changes, including urbanization, may affect local and regional climate. Primarily, her research interest is on holistic climate system research that can provide crucial insights on the potential impacts of climate change (whether due to land use or global warming or both) on society, especially in the Philippines, with the goal of providing science-based support to disaster risk mitigation, climate change adaptation, and sustainable development planning.
