I completed PhD and two years’ post-doctoral research at UCL in the areas of stress analysis, fatigue assessment, fracture mechanics modelling, non-destructive testing and underwater inspection reliability analysis for tubular welded joints in offshore jacket platforms.

Since then, I have worked in the UK marine and offshore industry for twenty years. At Kvaerner Oil and Gas Ltd, I performed the finite element analyses for North Sea offshore jacket platforms and risers. As a chartered naval architecture Engineer, I had 18 years' classification society hull and statutory plan approval experiences on the design of various types of ships and offshore installations.  At American Bureau of Shipping, as a Senior engineer I carried out the design review for compliance with applicable classification society Rules and statutory legislation for all types of vessels and floating units including ultra large container ships, gas carriers, oil & chemical tankers, FPSO conversions/new builds, offshore support vessels and FLNG etc. At Lloyd’s Register, as a lead specialist I performed the analysis and design review of various marine and offshore structures and was responsible for classification appraisal of the pump tower and containment system for many LNG carriers and FLNG units built in HHI, DSME and SHI, which cover cargo tank structural strength, fatigue, sloshing, vibration, risk based inspection and survival condition assessments.

From 2018 to 2021, I performed the research in areas of structural integrity of natural gas and carbon dioxide CO₂ transport pipelines at the University of Strathclyde for three years. During this period, I have successfully taught “Design and Construction of FPSOs”, “Advanced Marine Structures”, "Ship Structural Dynamics" and part of "Marine Engineering Fundamentals” modules to undergraduate and MSc students.

Since joining the Newcastle university in September 2021, I have been working on two Clean Maritime Demonstration research projects in the areas of smart and zero carbon shipping.
