Hello, and Welcome to my Web Application!

I am a scientist who focus on the multifaceted study of air quality and atmospheric phenomena, including the analysis of wildfire smoke on ozone, air pollutant monitoring, and the utilization of satellite and remote sensing data to assess atmospheric parameters. I am also deeply engaged in studying the wildfire smoke impacts on air quality, the physicochemical properties of atmospheric aerosols, the dynamics of new particle formation, and the development of predictive models using machine learning.

I hope everything is useful, thank you.
