Laboratory Facilities


        



Modeling and Inversion Lab adalah laboratorium interdisiplin ilmu dibawah sub-divisi Induksi Elektromagnetik pada kelompok keahlian (KK) Fisika Bumi dan Sistem Kompleks, Program Studi Fisika. Banyak mahasiswa pascasarjana (S2 atau S3) yang masuk lab ini melalui Program Studi Fisika (FI). Beberapa ada yang melalui Program Studi Teknik Panas Bumi (PB), Program Studi Sains Kebumian (SB), dan Program Studi Teknik Geofisika (TG).

Anggota Lab yang masih aktif baik sedang TA, Tesis, Disertasi ataupun Riset bisa dilihat di halaman Peoples, sedangkan alumni bisa dilihat disini. Bisa dilihat juga hasi penelitian anggota lab ini berupa Studi Mandiri/Kermantau, dan TA, Tesis dan Disertasi.

Jika tertarik bergabung dengan kami, silahkan mengontak langsung Wahyu Srigutomo, Ph.D. (wahyu@fi.itb.ac.id) atau lihat pendaftaran mahasiswa pascasarjana di SPs ITB.
