Hamid Nazeri, PhD

Rock Mechanics Division Manager

Doctor of Philosophy, Mining & Earth System Engineering, Colorado School of Mines, 2001
Master of Mining Engineering, University of Tehran, 1986
Bachelor of Mining Engineering, University of Tehran, 1983

Hamid directs projects to provide reliable/accurate rock mechanics test results and reports for clients. He determines requirements, customizes tests as needed, and delivers clear and accurate data on rock physical properties. He also manages testing quality assurance/control in compliance with applicable ASTM, ISRM guidelines and standards.

Geotechnical Background

Hamid’s initial experience in rock engineering began in 1993 as a research assistant at the Earth Mechanics Institute of Colorado School of Mines. Then in 1997, he joined Advanced Terra Testing. During his tenure at Advanced Terra Testing, he has had the opportunity to work in an independent geotechnical testing laboratory, which has allowed him to expand and grow his experience working with multiple clients and to develop/expand rock mechanics lab capabilities. Overall, he has 35 years of industrial experience, teaching at different universities (Colorado School of Mines, Metropolitan State University of Denver, Tehran University), research in rock mechanics, geotechnical, mechanics of materials, mining engineering, computer simulation and application of Discrete Element Method (DEM) numerical modeling.

Beyond the Lab

Hamid enjoys reading historical, scientific books. He loves to walk on different Colorado trails and watching documentary movies.
