Brian Bramanto, Ph.D. is an Assistant Professor of Physical Geodesy at Institut Teknologi Bandung (ITB), Indonesia. His research focuses on physical geodesy, gravimetry, geoid modeling, and the application of geodetic and satellite-based observations to study hydrological and environmental processes, including groundwater loss and land subsidence. He has actively contributed to the development of Indonesia’s official geoid model, INAGEOID2020 v.2.0, in collaboration with the Geospatial Information Agency (BIG). Dr. Bramanto has extensive experience in GNSS surveying, relative and absolute gravity measurements, and the integration of geodetic techniques for environmental monitoring. His recent work includes using GRACE/GRACE-FO satellite gravimetry to investigate hydrological dynamics in Indonesia.
