Biography

Originally from Sri Lanka, Sahan most recently migrated to New Zealand in 2011. After finishing high school in Wellington, he has completed a B.Eng (Honours) in Mechatronics conjoint with a B.Sc. in Physics. Sahan joined the Biomimetics Lab in July 2018 and completed his Masters' Thesis (Inkjet printing as a Fabrication Tool for DEA Electrodes and Microfluidics) with a First Class grade. Since then, he has begun his doctoral studies with the same research group.

 

Research | Current

The project lies in the frame of ABI’s multiscale modeling of traumatic brain injury, led by Vickie Shim. Mild traumatic brain injury (mTBI) (particularly sports-related concussion) is a significant issue for New Zealanders and worldwide. Yet there are still no definitive assessments of its existence or severity, as well as the impact of concussion on brain integrity and function let alone treatment option. In this context, we are working on mechanical in-plane stretching of 2D brain cell cultures and/or tissue explants.

This requires a platform that can apply mechanical strain at a high strain rate to a cell population. Soft actuators (namely dielectric elastomer actuators) have been successfully applied to the fabrication of deformable culture chambers able to apply a mechanical insult to cells. The main aim of the research is to develop a high-throughput cell-stretching platform in the form of a standard multi-well plate (at least 6, but ideally 12 or 24 wells).
