I am a lecturer at Laboratory of Geophysics, Universitas Gadjah Mada, Indonesia. I am interested in volcano stuffs. Mostly I use remote sensing technique, such as satellite, drones, camera, lidar, which combines with geophysics dataset to understand volcanic behaviors and assessing the hazards. If you are interested to collaborate with me, just send an email to: herlan_darmawan@mail.ugm.ac.id
