It was an honor to be able to co-present the State of the the Art Lecture on “MICP Soil Improvement and Its Application to Liquefaction Hazard Mitigation” at ICSMGE 2022 Sydney with Jason T. DeJong. The presentation represented the collective efforts of a large team of co-authors including Alexandra C.M. San Pablo, Charles M.R. Graddy, Douglas C. Nelson, Minyong Lee, Katerina Ziotopoulou, Maya El Kortbawi, Brina Montoya, and Tae-Hyuk Kwon. The paper “State of the Art: MICP Soil Improvement and Its Application to Liquefaction Hazard Mitigation” can be found here.
12/15/22 – A huge congratulations to Dr. Minyong Lee who submitted his Ph.D. dissertation entitled, “Biocementation for Liquefaction Mitigation: Examining Response, Development, and Deployment”, this past quarter! Minyong completed an unbelievable amount of outstanding research and will be sorely missed by all in our group! We are so excited to hear about what is next!
