DFI Traveling Lecturer
The DFI Traveling Lecturer is a prominent industry expert selected annually to travel and present a series of lectures to university students, professional groups and industry associations. The program promotes the field of geotechnical engineering and deep foundation construction by encouraging students to explore a career in the deep foundations industry, providing information on topics of interest to members of the industry, and raising awareness of how DFI and its activities support the industry. The lecture series runs from September 1 - August 31.
