After finishing her studies at UP, Perez became a fellow at NASA’s Goddard Space Flight Center Hydrospheric and Biospheric Sciences Laboratory. It was there that she realized how much data could be gleaned from satellite images. This would later drive her study on the use of satellite data for drought forecasting and the identification of ideal planting sites and seasons. Her work earned her international recognition as the first Filipina to win the 2018 ASEAN-US Science Prize for Women. Perez has already moved on to the second phase of her research, while findings from the previous phase have been turned over for use to the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) and the Bureau of Soils and Water Management. Once vetted by these agencies, Perez’s research could be used to help farmers all over the country.
