Dr Cholachat Rujikiatkamjorn is a research associate in School of Civil, Mining and Environmental Engineering. His areas of interest are in geotechnical and rail way engineeirng. He has applied his research findings in the area of sub-surface drainage for soft soil improvement under railway and road embankments. He is currently working as a researcher under the guidance of Prof. Indraratna in two key projects, ARC-DP (Particle Breakage) and CRC-Rail (formation-Ballast interaction). Recently, he received a Trailblazer Award-2006 for the innovation and commercial potential of my research on stabilization of highly compressible soils.
