I'm 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, I have two stints as a postdoc at Earth Science and Engineering, Imperial College London; and at Institut de Mathématiques de Toulouse, France. I received an MSc and a PhD in Applied Mechanics from National Taiwan University, and a first degree in Mechanical Engineering from Institut Teknologi Bandung, Indonesia.

My research combines a range of state-of-the-art modelling and experimental techniques to understand flow and transport in natural porous media. It 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. I incorporate 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. To help interpret these data onto the larger scales, I 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. For problems involving mineral dissolution by fluids, I developed a multiscale method based on continuous-time random walk where transport is governed not by a set of governing equations, but by transit-time distributions. During my PhD study, I developed mathematical and numerical models for gas flow at a mesoscopic regime — where the characteristic length of the problem is comparable to the gas mean-free path.
