- Funded by DOST and in collaboration with the Prof. Yuan of the National Sun Yat Sen University in Taiwan, chemical characteristics of PM2.5 aerosols in southern Taiwan and northern Philippines is being investigated.
- Funded by the OML Center, WeatherUP is a crowd-source weather app for the Philippines, available on ios and android.
- I am doing air quality modeling studies using WRF-chemistry. One of the goals is to look at the amount of air pollution we have in Metro Manila.
- I currently run a weather website called Weather-Manila.com using the wrf model, with 5-day weather forecast for different cities in the Philippines.
