Dr. Gemma Teresa Narisma is currently the Executive Director of the Manila Observatory and Associate Professor at the Physics Department of the Ateneo de Manila University. She is also a Coordinating Lead Author for the Intergovernmental Panel on Climate Change Assessment Report 6 (IPCC-AR6).  

Dr. Narisma earned her BS in Applied Physics and MSc in Environmental Science degrees from the University of the Philippines Diliman. She received her PhD in Atmospheric Science from the Macquarie University in Sydney, Australia. She later joined the Center for Sustainability and the Global Environment (SAGE) at the University of Wisconsin, Madison as a Research Associate. For her exemplary contributions to science, she received the following awards: NAST Outstanding Young Scientist in Atmospheric Science in 2012, The Outstanding Women in the Nation’s Service (TOWNS) award in 2013, and the National Research Council of the Philippines (NRCP) Achievement Award in Earth and Space Sciences in March 2018.

Her areas of research include climate change and variability analyses using regional climate modeling and observation data. She also has done extensive work on land-atmosphere interactions and how changes in the biosphere through land use and land cover changes, including urbanization, 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.
