|Durability, long-term behavior and performance of composite riser materials.|
The objective of this research is to study the long-term behaviour of composite risers made of new composite materials, subjects to harsh environmental factors including diffusion, cyclic loading, and other external loading. Based on Time-temperature superposition, the long term degradation of the materials can be predicted using short term tests.

|Integration, Prototyping and Proof of concept Testing of composite Risers|
The aim of this project is to integrate, prototyping and proof of concept testing of both rigid and flexible composite risers. The testing is design to verify the capability of the prototype model to sustain the design pressure, and to establish the actual collapse pressure.

|Design and development of a compact swept source optical coherence tomography (SSOCT) imaging system with enhanced imaging capability for bio imaging applications.|
The project aim to develop a novel fiber optic interferometer and galvo mirror based beam delivery system. The system is capable of real-time data acquisition using high speed digitizer and control signal generation for laser beam steering setup for imaging. The SSOCT system uses an efficient wavenumber calibration scheme. The developed system can be applied to 1) In situ and quantitative imaging of bacterial biofilm using OCT/OCM, 2) Nanoparticle based contrast enhancement and photothermal applications, and 3) Anterior chamber imaging for Glaucoma detection.
