Biography
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. The UKICIS features in the UK Indonesia Partnership Roadmap 2022-2024 as a vehicle for research and innovation collaboration between the two countries.
Bagus is the recipient of Vice-Chancellor's Medal 2021 in recognition of his outstanding contribution to the university.
Expertise Summary
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.
Teaching Summary
Bagus is the convenor of Year 1 Fluid Mechanics CHEE1034 module, and Year 4 Advanced Computational Method CHEE4004.

Current Research
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).
