Dr. Raghu’s research has been applids in nature. Recently his research has been focused on modelling of settlement of landﬁlls. He has also worked on chromium contamination, disposal of water treatment plant residuals and reuse of contaminated soils. A technique for designing and constructing structures in and on cavernous carbonate formations was developed by him. He also won several awards such as the Robert Van Houten award for Teaching Excellence (University-wide), Engineer of the year by ASCE NJ Section and recently Service to the Profession award by Central Jersey Section ASCE.
