Jim Mathis

Based in Washington state, Dr. Mathis operates an international practice focusing solely on premium rock mechanics engineering and rock mass characterization work, primarily for the mining industry.

Originally from Nevada, he obtained a degree in mining engineering from University of Nevada - Reno in 1981. He was employed after graduation with Call and Nicholas, conducting statistical rock mechanic source code development and statistical rock mechanics design. He returned to school in January 1984 and graduated with a doctorate degree in rock mechanics from the University of Lulea (Sweden) in 1988. Employment thereafter was primarily with Steffen Robertson and Kirsten as their senior North American rock mechanics engineer. He resigned this position in August of 1995 and began Zostrich Geotechnical (formally Ursa Engineering).

On these, and other projects, he has instructed client personnel and advised clients on correct data collection methodology. Design is conducted using both statistical packages which he has coded coupled with the best available from other sources.

Dr. Mathis has authored several Edumine web-based courses on Rock Mechanics.
