The Aerosol Particle Technology Lab (APT Lab) at IIT Goa works predominantly in the research area of aerosol particle characterization and quantification of particulate matter emissions. The group works on several experimental and computational topics in aerosol science and technology. In addition to aerosol science-related topics, the group also works on topics related to indoor air quality, air pollutants, aggregation of particles in aerosol and colloidal systems, ML applications in aerosol science and Particulate technology.

Updates:

• July 2025: Our collaborative work on the characterization of fine and ultrafine particulate matter from various welding sources in industrial settings has been accepted for publication in Atmospheric Pollution research. The work was carried out in collaboration with Prof. Sachin Kore's group at IIT Goa. Congratulations Rubal.
