Assistant Professor - Chemical &environmental Engineering, 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 Fluids and Thermal Engineering Research Group.
Bagus' research is characterised by its diversity as reflected in his publication output which includes publications on rarefied quantum gas dynamics, multiscale method developments, direct pore-scale simulations and reactive transport modelling.
Bagus is the convenor of Fluid Mechanics module: H81FLM

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).
