Although Alberta is not generally considered as an earthquake-active zone, it is vital to educate the engineering communities with fundamentals of mitigation, preparedness, and recovery of earthquake hazards. Before joining University of Alberta, Dr Deng has been investigating an innovative rocking shallow foundation design methodology and soil stability using both physical modeling tools and numerical methods. Dr Deng is persistently interested in the research and education of geotechnical earthquake engineering covering the fields of,
Dr. Deng's selected research projects are:
Dr. Deng is currently working on a few initiatives in geotechnical centrifuge modeling and worm-assisted tailings settling.
