John Rogie, PG, EIT, CPT Inc.’s president and principal rig operator, is a California registered Professional Geologist. Prior to forming CPT Inc., John worked as a project geologist and staff engineer on geotechnical investigations for projects located in liquefaction hazard zones, and is familiar with Special Publication 117 and using CPT data to model liquefaction and settlement potential. John was also a member of the Volcano Hazards Team of the Menlo Park Water Resources division of the US Geological Survey from 1999 to 2002. John’s research at the USGS focused on monitoring vadose zone gas flow in areas of volcanic unrest and hydrothermal systems. John has published in Earth & Planetary Science Letters and the Journal of Geophysical Research on the topics of soil gas monitoring and time-series analysis of meteorological influence on crustal permeability assessment.
