Dr. Joaquin Ruiz, who is a dean and member of the geosciences faculty at the University
of Arizona and immediate past president of the Geological Society of America, will
present "The Evolution of Earth" on Friday, Oct. 14, at 3 p.m. in room 102 of VanderWerf
Hall as the 2011 Gentile Interdisciplinary Lecture at Hope College.

America, following a previous year's service as vice president.
As a scientist with equal abilities in chemistry and in geology, he addresses many
first-order problems in the earth sciences, such as the development of new isotope
systems for studying ore deposits and the tectonic processes involved in the growth
and evolution of Mexico. His research team addresses problems ranging from the origins
of life to present-day climate change.
Ruiz received his B.S. in geology and B.S. in chemistry at the University of Miami
in 1977. He received his M.S. and Ph.D. in geology from the University of Michigan
in 1980 and 1983 respectively.

for Excellence in Science and Technology Program. He has served as associate editor
of the "American Journal of Science," "Geology," "Revista" and "Geofisica International"
of the Institute of Geology, UNAM.
The Gentile Interdisciplinary Lectureship at Hope was established in 2005 by faculty
colleagues, former students and friends of Dr. James Gentile. Gentile joined the Hope
faculty in 1976 and served as dean for the natural sciences from 1988 to 2005, when
he became president of Research Corporation, a private foundation in Tucson, Ariz.,
that supports basic research in the physical sciences.
VanderWerf Hall is located along 10th Street between Central and College avenues.
