Our main research focus on the study of clathrate hydrates, from the SCIENCE (fundamental) to the ENGINEERING (applied), so that we can further our understanding of their properties and develop solutions for their application. The research in my group covers a number of different areas for hydrates in flow assurance (fluid characterization, risk assessment, multiphase flow, extreme conditions, bedding/deposition, dispersion/agglomeration) and science (nucleation/growth, phase equilibria, metastability, inhibition, structure/composition, structural transition). Our research is based on experimental, theoretical, and computational approaches, so that a comprehensive understanding can developed for hydrates.
