Biography

Samanthika completed her PhD at the University of Western Australia in 1999. From 1999-2003, she worked as a Postdoctoral Fellow at the Centre for Geotechnical Research at the University of Sydney. In 2003, she joined the University of Wollongong as a Lecturer and was promoted to Senior Lecturer in 2005. She joined the School of Engineering at UWS in 2009 as a Senior Lecturer. In 2007, she received the Thomas A. Middlebrooks Award from the American Society of Civil Engineers for research carried out in the design of pile foundations in seismically active regions. In 2008, she received the University of Wollongong Vice Chancellor's Award for outstanding contribution for Teaching and Learning.
