T. Leslie Youd
is an American geotechnical engineer
and earthquake engineer
, and is one of the pre-eminent expert researchers on earthquake liquefaction
and ground failure. He has gained an international reputation in this field.
T. Leslie Youd received his BES
in civil engineering
from Brigham Young University
in 1964. He then attended Iowa State University
where he received his PhD
in civil engineering in 1967. He performed post doctoral
study in soil mechanics
and engineering seismology
from 1975 to 1976 at Imperial College of Science and Technology
Youd's research has been primarily concerned with the phenomenon of soil liquefaction
, and the associated lateral spreading
which can occur. Youd has published over 140 research papers Youd's best-known papers are on the prediction of the magnitude of lateral spreading
