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. Currently she is a Professor at the University of Western Sydney. 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. In 2013, She received the Australian Geomechanics Award for research carried out on geosynthetic reinforced deep cement mixed column supported embankments. In 2015, She is the recipient of the Outstanding Reviewer Award from Elsevier for the journal Computers and Geotechnics (ISSN: 0266-352X) for 2013-2014 in recognition of the high quality of her professional contribution based on the quality of the submitted review reports. In 2019 June she was elected as a Fellow of the Institution of Engineers, Australia. In 2021 June, She was elected as a Fellow of the American Society of Civil Engineers and She is the first and only female elected from Australia for this prestigious Fellowship.
