Assistant Professor, Faculty of Engineering
Bagus is an Assistant Professor of Chemical and Environmental Engineering at the University of Nottingham with a joint affiliation with Virginia Tech, United States. Prior to joining Nottingham university, he was a postdoctoral research associate at Earth Science and Engineering, Imperial College London; and at Institut de Mathématiques de Toulouse, France. He received an MSc and a PhD in Applied Mechanics from National Taiwan University. He received his first degree in Mechanical Engineering from Institut Teknologi Bandung, Indonesia.
He is a member of the GeoEnergy Research Centre, and the Environmental Fluid Mechanics and Geoprocesses Research Group. Bagus is the steering committee coordinator of the UK-Indonesia Consortium for Interdisciplinary Sciences (UKICIS) - a consortium of research intensive universities where Nottingham is a founding member of.
Bagus is the recipient of Vice-Chancellor's Medal 2021 in recognition of his outstanding contribution to the university.
Bagus' research is characterized by its interdisciplinarity. He develops mathematical and numerical models, and combines imaging techniques using X-ray CT and Magnetic Resonance Imaging to solve flow and reactive transport problems in complex geometries across a wide range of flow regimes. His methods have been applied for solving problems in the fields of hydro-geology, bio-architecture, peatlands management, groundwater transport, and carbon capture and storage.
Bagus is the convenor of Year 1 Fluid Mechanics CHEE1034 module, and Year 4 Advanced Computational Method CHEE4004.

Bagus' research combines a range of state-of-the-art modelling and experimental techniques to understand flow and transport in natural porous media. His research aims at overcoming the scientific challenges due to complex geometry and bio-geo-chemical processes; and a large disparity in scales in many subsurface flow and transport problems. He incorporates X-ray micro-CT, and Nuclear Magnetic Resonance imaging technologies to probe into flow and transport at a micro-, and milimetres scale. These provide the basis for validation and direct inputs for the numerical models. Bagus has developed mathematical and numerical models for flow at a rarefied (where the characteristic length of the problem is comparable to the gas mean-free path), and a continuum regime. He developed bespoke multiscale methods for flow and transport in genuinely heterogeneous media where sub-scale information is communicated to the larger scales by means of multiscale basis functions. He also developed a multiscale method based on continuous-time random walk for problems involving mineral dissolution (reactive transport).
