He received his Doctor of Science in Civil Engineering at the Massachusetts Institute of Technology in 1989. His teaching, research, and consultancy expertise is in soil behavior with a focus on field and laboratory measurements for geotechnical engineering site characterization programs. He has been a Principal/Co-Principal Investigator on numerous projects that included research on drilling and sampling of soils, in situ testing, laboratory measurement of soil behavior, and selection of soil design parameters. He was PI of the recently completed $2.4 million US National Science Foundation project on "Developing International Protocols for Offshore Sediments and their Role in Geohazards: Characterization, Assessment, and Mitigation." He has published refereed research findings in the major geotechnical engineering journals and has presented several invited Keynote and State-of-the-Art papers at national and international conferences. He has received several UMass Amherst outstanding teaching and research awards. Other awards include the ASCE NY MET Section GZA Lecture Award (2013); Sowers State-of-the-Art Lecture Award, Georgia Tech (2006); Gledden Visiting Senior Fellowship, UWA (2005); and the Research Council of Norway Guest Researcher Fellowship (1997).
